net: igmp: fix data-race in igmp_ifc_timer_expire()
Fix the data-race reported by syzbot [1]
Issue here is that igmp_ifc_timer_expire() can update in_dev->mr_ifc_count
while another change just occured from another context.
in_dev->mr_ifc_count is only 8bit wide, so the race had little
consequences.

net: igmp: fix data-race in igmp_ifc_timer_expire()
Fix the data-race reported by syzbot [1]
Issue here is that igmp_ifc_timer_expire() can update in_dev->mr_ifc_count
while another change just occured from another context.
in_dev->mr_ifc_count is only 8bit wide, so the race had little
consequences.

GDB aarch64 malfunctions w/Linaro / ARM gcc 10.3 compiler
by Dietmar May
I'm compiling and running a bare metal AArch64 bootloader using 3
different compilers: the Linaro / ARM GCC 10.3.1 compiler, the Linaro /
ARM GCC 10.2.1 compiler, and an in-house built GCC 10.2.0 compiler.
GDB will single step using the either of the GCC 10.2 compilers; but
runs without halting when step is requested - or perhaps steps multiple
instructions - when built using the Linaro / ARM-supplied GCC 10.3.1.
Eclipse CDT (v4.20 aka 2021-06) is able to correlate debugging
information from binaries built with either of the gcc 10.2 toolchains,
and to single step correctly through the program. Breakpoints work as
expected. Registers display fine.
Eclipse CDT is not able to correlate current PC location to source code
using the binary built with Linaro / ARM 10.3, instead bringing up a
disassembly window. Breakpoints placed at assembly instructions in the
editor do not work.
I've tried three different GDB versions - ARM's supplied 10.2 and 10.3
GDB, and the in-house built GDB. Results are the same.
The same makefile is used to create the binaries, with just a few macro
definitions to switch. The only compiler flag of interest is
-march=armv8.2-a (and of course -g -O0). -mtune=cortex-a53 doesn't help.
The board is connected via JTAG using OpenOCD 0.11.0+ and an Olimex
ARM-USB-OCD-H adapter.
I'm building in a cygwin shell on Windows 10 version 21H1 using the
compilers:
gcc-arm-10.3-2021.07-mingw-w64-i686-aarch64-none-elf.tar.xz
gcc-arm-10.2-2020.11-mingw-w64-i686-aarch64-none-elf.tar.xz
downloaded from:
https://developer.arm.com/tools-and-software/open-source-software/developer…
Differences in compiler configuration (gcc -v) are:
Failing - Linaro / ARM GCC 10.3(.1):
--enable-checking=release
--target=aarch64-none-elf
--with-libiconv-prefix=/data/jenkins/workspace/GNU-toolchain/arm-10-4/build-mingw-aarch64-none-elf/host-tools
Working - in house GCC 10.2.1:
--build=x86_64-w64-mingw32
--disable-libffi
--disable-libgomp
--disable-libmudflap
--disable-libssp
--disable-libstdcxx-pch
--disable-lto
--disable-win32-registry
--enable-multilib
--target=aarch64-elf
--with-gcc
--with-gnu-as
--with-gnu-ld
--with-host-libstdcxx='-static-libgcc -Wl,-Bstatic,-lstdc++,-Bdynamic -lm'
--with-multilib-list=lp64,ilp32
--with-stabs
--with-sysroot=/build/aarch64-elf_10.2.0/cross-gcc/aarch64-elf
--with-zstd=/build/aarch64-elf_10.2.0/host
Has anyone been able to perform hardware debugging of binaries built
with the latest 10.3 builds using GDB (and maybe even Eclipse CDT)?
Any suggestions as to other steps to try?
Thanks.

net: igmp: fix data-race in igmp_ifc_timer_expire()
Fix the data-race reported by syzbot [1]
Issue here is that igmp_ifc_timer_expire() can update in_dev->mr_ifc_count
while another change just occured from another context.
in_dev->mr_ifc_count is only 8bit wide, so the race had little
consequences.

commit 341db343768bc44f3512facc464021730d64071c
Author: Linus Walleij <linus.walleij(a)linaro.org>
Date: Sun May 23 00:50:39 2021 +0200
power: supply: ab8500: Move to componentized binding
[ Upstream commit 1c1f13a006ed0d71bb5664c8b7e3e77a28da3beb ]
The driver has problems with the different components of
the charging code racing with each other to probe().
This results in all four subdrivers populating battery
information to ascertain that it is populated for their
own needs for example.
Fix this by using component probing and thus expressing
to the kernel that these are dependent components.
The probes can happen in any order and will only acquire
resources such as state container, regulators and
interrupts and initialize the data structures, but no
execution happens until the .bind() callback is called.
The charging driver is the main component and binds
first, then bind in order the three subcomponents:
ab8500-fg, ab8500-btemp and ab8500-chargalg.
Do some housekeeping while we are moving the code around.
Like use devm_* for IRQs so as to cut down on some
boilerplate.

[ Upstream commit 1c1f13a006ed0d71bb5664c8b7e3e77a28da3beb ]
The driver has problems with the different components of
the charging code racing with each other to probe().
This results in all four subdrivers populating battery
information to ascertain that it is populated for their
own needs for example.
Fix this by using component probing and thus expressing
to the kernel that these are dependent components.
The probes can happen in any order and will only acquire
resources such as state container, regulators and
interrupts and initialize the data structures, but no
execution happens until the .bind() callback is called.
The charging driver is the main component and binds
first, then bind in order the three subcomponents:
ab8500-fg, ab8500-btemp and ab8500-chargalg.
Do some housekeeping while we are moving the code around.
Like use devm_* for IRQs so as to cut down on some
boilerplate.

tree-optimization/101801 - remove vect_worthwhile_without_simd_p
This removes the cost part of vect_worthwhile_without_simd_p, retaining
only the correctness bits. The reason is that the cost heuristic
do not properly account for SLP plus the check whether "without simd"
applies misfires for AVX512 mask vectors at the moment, leading to
missed vectorizations there.
Any costing decision should take place in the cost modeling, no
single stmt is to disable all vectorization on its own.

tree-optimization/101801 - remove vect_worthwhile_without_simd_p
This removes the cost part of vect_worthwhile_without_simd_p, retaining
only the correctness bits. The reason is that the cost heuristic
do not properly account for SLP plus the check whether "without simd"
applies misfires for AVX512 mask vectors at the moment, leading to
missed vectorizations there.
Any costing decision should take place in the cost modeling, no
single stmt is to disable all vectorization on its own.

c-family: Fix ICE in get_atomic_generic_size [PR96545]
As the testcase shows, we would ICE if the type of the first argument of
various atomic builtins was pointer to (non-void) incomplete type, we would
assume that TYPE_SIZE_UNIT must be non-NULL. This patch diagnoses it
instead. And also changes the TREE_CODE != INTEGER_CST check to
!tree_fits_uhwi_p, as we use tree_to_uhwi after this and at least in theory
the int could be too large and not fit.

Fix FindZ3.cmake to support static libraries and Windows
Use absolute path to link z3 to allow builds both on windows and linux
since the library name is platform dependent for Z3 (libz3 on Windows
and z3 on Linux) and MSVC does not recognized -L and -l options.
Fix CMAKE_CROSSCOMPILING that does not work correctly since it uses
Z3_BUILD_VERSION instead of Z3_BUILD_NUMBER
Fix building with the static version of z3 library (supersedes D80227).
- Build the Z3 version detection code as C++, since the static
library brings in libstdc++ symbols
- Detect threading support and link against threading, in the
(likely) case Z3 was built with threads
Exposed compilation error from building a program that is used to detect
z3 version in the warning message, to simplify troubleshooting.

and __kmpc_get_hardware_num_blocks. If the thread_limit and the num_teams are constant,
these calls can be folded to the constant value.
In commit D106033 we have the optimization phase. This commit adds the attributes to
the outlined function for the grid size. the two attributes are `omp_target_num_teams` and
`omp_target_thread_limit`. These values are added as long as they are constant.
Two functions are created `getNumThreadsExprForTargetDirective` and
`getNumTeamsExprForTargetDirective`. The original functions `emitNumTeamsForTargetDirective`
and `emitNumThreadsForTargetDirective` identify the expresion and emit the code.
However, for the Device version of the outlined function, we cannot emit anything.
Therefore, this is a first attempt to separate emision of code from deduction of the
values.

* trans-decl.c (convert_CFI_desc): Only copy out the descriptor
if necessary.
* trans-expr.c (gfc_conv_gfc_desc_to_cfi_desc): Updated attribute
handling which reflect a previous intermediate version of the
standard. Only copy out the descriptor if necessary.

PR fortran/93308
PR fortran/93963
PR fortran/94327
PR fortran/94331
PR fortran/97046
gcc/fortran/ChangeLog:
* trans-decl.c (convert_CFI_desc): Only copy out the descriptor
if necessary.
* trans-expr.c (gfc_conv_gfc_desc_to_cfi_desc): Updated attribute
handling which reflect a previous intermediate version of the
standard. Only copy out the descriptor if necessary.
libgfortran/ChangeLog:
* runtime/ISO_Fortran_binding.c (cfi_desc_to_gfc_desc): Add code
to verify the descriptor. Correct bounds calculation.
(gfc_desc_to_cfi_desc): Add code to verify the descriptor.
gcc/testsuite/ChangeLog:
* gfortran.dg/ISO_Fortran_binding_1.f90: Add pointer attribute,
this test is still erroneous but now it compiles.
* gfortran.dg/bind_c_array_params_2.f90: Update regex to match
code changes.
* gfortran.dg/PR93308.f90: New test.
* gfortran.dg/PR93963.f90: New test.
* gfortran.dg/PR94327.c: New test.
* gfortran.dg/PR94327.f90: New test.
* gfortran.dg/PR94331.c: New test.
* gfortran.dg/PR94331.f90: New test.

[ACTIVITY] report week ending 6 Aug
by Peter Maydell
Progress:
* UM-2 [QEMU upstream maintainership]
+ Usual release work (rc2 now out) and code review
+ Continuing with systick timer refactoring. This has turned out a bit
more complicated than I expected: had to do a preliminary refactor
to move some stuff out of the NVIC device into the armv7m container;
also needed to add support in the Clock APIs for frequency multiply
and divide for the benefit of the stm32 SoCs which drive the systick
reference clock at 1/8 the speed of the main CPU clock

commit 2e96b5f14e4025691b57d2301d71aa6092ed44bc
Author: Aldy Hernandez <aldyh(a)redhat.com>
Date: Tue Jun 15 12:32:51 2021 +0200
Backwards jump threader rewrite with ranger.
This is a rewrite of the backwards threader with a ranger based solver.
The code is divided into two parts: the path solver in
gimple-range-path.*, and the path discovery bits in
tree-ssa-threadbackward.c.
The legacy code is still available with --param=threader-mode=legacy,
but will be removed shortly after.
gcc/ChangeLog:
* Makefile.in (tree-ssa-loop-im.o-warn): New.
* flag-types.h (enum threader_mode): New.
* params.opt: Add entry for --param=threader-mode.
* tree-ssa-threadbackward.c (THREADER_ITERATIVE_MODE): New.

+Our new threader is threading things a bit too early, and causing the
+testcase in gcc.dg/shrink-wrap-loop.c to fail.
+
+ The gist is this BB inside a loop:
+
+ <bb 6> :
+ # p_2 = PHI <p2_6(D)(2), p_12(5)>
+ if (p_2 != 0B)
+ goto <bb 3>; [INV]
+ else
+ goto <bb 7>; [INV]
+
+Our threader can move this check outside of the loop (good). This is
+done before branch probabilities are calculated and causes the probs
+to be calculated as:
+
+<bb 2> [local count: 216361238]:
+ if (p2_6(D) != 0B)
+ goto <bb 7>; [54.59%]
+ else
+ goto <bb 6>; [45.41%]
+
+Logically this seems correct to me. A simple check outside of a loop
+should slightly but not overwhelmingly favor a non-zero value.
+
+Interestingly however, the old threader couldn't get this, but the IL
+ended up identical, albeit with different probabilities. What happens
+is that, because the old code could not thread this, the p2 != 0 check
+would remain inside the loop and probs would be calculated thusly:
+
+ <bb 6> [local count: 1073741824]:
+ # p_2 = PHI <p2_6(D)(2), p_12(5)>
+ if (p_2 != 0B)
+ goto <bb 3>; [94.50%]
+ else
+ goto <bb 7>; [5.50%]
+
+Then when the loop header copying pass ("ch") shuffled things around,
+the IL would end up identical to my early threader code, but with the
+probabilities would remain as 94.5/5.5.
+
+The above discrepancy causes the RTL ifcvt pass to generate different
+code, and by the time we get to the shrink wrapping pass, things look
+sufficiently different such that the legacy code can actually shrink
+wrap, whereas our new code does not.
+
+IMO, if the loop-ch pass moves conditionals outside of a loop, the
+probabilities should be adjusted, but that does mean the shrink wrap
+won't happen for this contrived testcase.

[AArch64] Fix build for non-default languages
The SVE PCS support broke go, D and Ada because those languages don't
call TARGET_INIT_BUILTINS. We therefore ended up trying to get the
TYPE_MAIN_VARIANT of a null __SVBool_t.
We shouldn't really need to apply TYPE_MAIN_VARIANT there anyway,
since the ABI-defined types are (and need to be) their own main
variants. This patch asserts for that instead.

commit 341db343768bc44f3512facc464021730d64071c
Author: Linus Walleij <linus.walleij(a)linaro.org>
Date: Sun May 23 00:50:39 2021 +0200
power: supply: ab8500: Move to componentized binding
[ Upstream commit 1c1f13a006ed0d71bb5664c8b7e3e77a28da3beb ]
The driver has problems with the different components of
the charging code racing with each other to probe().
This results in all four subdrivers populating battery
information to ascertain that it is populated for their
own needs for example.
Fix this by using component probing and thus expressing
to the kernel that these are dependent components.
The probes can happen in any order and will only acquire
resources such as state container, regulators and
interrupts and initialize the data structures, but no
execution happens until the .bind() callback is called.
The charging driver is the main component and binds
first, then bind in order the three subcomponents:
ab8500-fg, ab8500-btemp and ab8500-chargalg.
Do some housekeeping while we are moving the code around.
Like use devm_* for IRQs so as to cut down on some
boilerplate.

commit 341db343768bc44f3512facc464021730d64071c
Author: Linus Walleij <linus.walleij(a)linaro.org>
Date: Sun May 23 00:50:39 2021 +0200
power: supply: ab8500: Move to componentized binding
[ Upstream commit 1c1f13a006ed0d71bb5664c8b7e3e77a28da3beb ]
The driver has problems with the different components of
the charging code racing with each other to probe().
This results in all four subdrivers populating battery
information to ascertain that it is populated for their
own needs for example.
Fix this by using component probing and thus expressing
to the kernel that these are dependent components.
The probes can happen in any order and will only acquire
resources such as state container, regulators and
interrupts and initialize the data structures, but no
execution happens until the .bind() callback is called.
The charging driver is the main component and binds
first, then bind in order the three subcomponents:
ab8500-fg, ab8500-btemp and ab8500-chargalg.
Do some housekeeping while we are moving the code around.
Like use devm_* for IRQs so as to cut down on some
boilerplate.

commit 261d5a4a459bd49942e53bc83334ccc7154a09d5
Author: Jonathan Wakely <jwakely(a)redhat.com>
Date: Thu Jul 22 14:48:27 2021 +0100
libstdc++: Reduce header dependencies on <array> and <utility>
This refactoring reduces the memory usage and compilation time to parse
a number of headers that depend on std::pair, std::tuple or std::array.
Previously the headers for these class templates were all intertwined,
due to the common dependency on std::tuple_size, std::tuple_element and
their std::get overloads. This decouples the headers by moving some
parts of <utility> into a new <bits/utility.h> header. This means that
<array> and <tuple> no longer need to include the whole of <utility>,
and <tuple> no longer needs to include <array>.
This decoupling benefits headers such as <thread> and <scoped_allocator>
which only need std::tuple, and so no longer have to parse std::array.
Some other headers such as <any>, <optional> and <variant> no longer
need to include <utility> just for the std::in_place tag types, so
do not have to parse the std::pair definitions.
Removing direct uses of <utility> also means that the std::rel_ops
namespace is not transitively declared by other headers.
Signed-off-by: Jonathan Wakely <jwakely(a)redhat.com>
libstdc++-v3/ChangeLog:
* include/Makefile.am: Add bits/utility.h header.
* include/Makefile.in: Regenerate.

to new header.
* include/std/type_traits (__is_tuple_like_impl<tuple<T...>>):
Move to <tuple>.
(_Index_tuple, _Build_index_tuple, integer_sequence): Likewise.
(in_place_t, in_place_index_t, in_place_type_t): Likewise.
* include/bits/ranges_util.h: Include new header instead of
<utility>.
* include/bits/stl_pair.h (tuple_size, tuple_element): Move
partial specializations for std::pair here.
(get): Move overloads for std::pair here.
* include/std/any: Include new header instead of <utility>.
* include/std/array: Likewise.
* include/std/memory_resource: Likewise.
* include/std/optional: Likewise.
* include/std/variant: Likewise.

* include/std/version (__cpp_lib_tuples_by_type): Change type
to long.
* testsuite/20_util/optional/84601.cc: Include <utility>.
* testsuite/20_util/specialized_algorithms/uninitialized_fill/constrained.cc:
Likewise.
* testsuite/23_containers/array/tuple_interface/get_neg.cc:
Adjust dg-error line numbers.
* testsuite/std/ranges/access/cbegin.cc: Include <utility>.

libstdc++: Reduce header dependencies on <array> and <utility>
This refactoring reduces the memory usage and compilation time to parse
a number of headers that depend on std::pair, std::tuple or std::array.
Previously the headers for these class templates were all intertwined,
due to the common dependency on std::tuple_size, std::tuple_element and
their std::get overloads. This decouples the headers by moving some
parts of <utility> into a new <bits/utility.h> header. This means that
<array> and <tuple> no longer need to include the whole of <utility>,
and <tuple> no longer needs to include <array>.
This decoupling benefits headers such as <thread> and <scoped_allocator>
which only need std::tuple, and so no longer have to parse std::array.
Some other headers such as <any>, <optional> and <variant> no longer
need to include <utility> just for the std::in_place tag types, so
do not have to parse the std::pair definitions.
Removing direct uses of <utility> also means that the std::rel_ops
namespace is not transitively declared by other headers.
Signed-off-by: Jonathan Wakely <jwakely(a)redhat.com>
libstdc++-v3/ChangeLog:
* include/Makefile.am: Add bits/utility.h header.
* include/Makefile.in: Regenerate.
* include/bits/utility.h: New file.
* include/std/utility (tuple_size, tuple_element): Move
to new header.
* include/std/type_traits (__is_tuple_like_impl<tuple<T...>>):
Move to <tuple>.
(_Index_tuple, _Build_index_tuple, integer_sequence): Likewise.
(in_place_t, in_place_index_t, in_place_type_t): Likewise.
* include/bits/ranges_util.h: Include new header instead of
<utility>.
* include/bits/stl_pair.h (tuple_size, tuple_element): Move
partial specializations for std::pair here.
(get): Move overloads for std::pair here.
* include/std/any: Include new header instead of <utility>.
* include/std/array: Likewise.
* include/std/memory_resource: Likewise.
* include/std/optional: Likewise.
* include/std/variant: Likewise.
* include/std/tuple: Likewise.
(__is_tuple_like_impl<tuple<T...>>): Move here.
(get) Declare overloads for std::array.
* include/std/version (__cpp_lib_tuples_by_type): Change type
to long.
* testsuite/20_util/optional/84601.cc: Include <utility>.
* testsuite/20_util/specialized_algorithms/uninitialized_fill/constrained.cc:
Likewise.
* testsuite/23_containers/array/tuple_interface/get_neg.cc:
Adjust dg-error line numbers.
* testsuite/std/ranges/access/cbegin.cc: Include <utility>.
* testsuite/std/ranges/access/cend.cc: Likewise.
* testsuite/std/ranges/access/end.cc: Likewise.

Author: Linus Walleij <linus.walleij(a)linaro.org>
Date: Sun May 23 00:50:39 2021 +0200
power: supply: ab8500: Move to componentized binding
[ Upstream commit 1c1f13a006ed0d71bb5664c8b7e3e77a28da3beb ]
The driver has problems with the different components of
the charging code racing with each other to probe().
This results in all four subdrivers populating battery
information to ascertain that it is populated for their
own needs for example.
Fix this by using component probing and thus expressing
to the kernel that these are dependent components.
The probes can happen in any order and will only acquire
resources such as state container, regulators and
interrupts and initialize the data structures, but no
execution happens until the .bind() callback is called.
The charging driver is the main component and binds
first, then bind in order the three subcomponents:
ab8500-fg, ab8500-btemp and ab8500-chargalg.
Do some housekeeping while we are moving the code around.
Like use devm_* for IRQs so as to cut down on some
boilerplate.

commit 341db343768bc44f3512facc464021730d64071c
Author: Linus Walleij <linus.walleij(a)linaro.org>
Date: Sun May 23 00:50:39 2021 +0200
power: supply: ab8500: Move to componentized binding
[ Upstream commit 1c1f13a006ed0d71bb5664c8b7e3e77a28da3beb ]
The driver has problems with the different components of
the charging code racing with each other to probe().
This results in all four subdrivers populating battery
information to ascertain that it is populated for their
own needs for example.
Fix this by using component probing and thus expressing
to the kernel that these are dependent components.
The probes can happen in any order and will only acquire
resources such as state container, regulators and
interrupts and initialize the data structures, but no
execution happens until the .bind() callback is called.
The charging driver is the main component and binds
first, then bind in order the three subcomponents:
ab8500-fg, ab8500-btemp and ab8500-chargalg.
Do some housekeeping while we are moving the code around.
Like use devm_* for IRQs so as to cut down on some
boilerplate.

nfc: fdp: constify several pointers
Several functions do not modify pointed data so arguments and local
variables can be const for correctness and safety. This allows also
making file-scope nci_core_get_config_otp_ram_version array const.

nfc: fdp: constify several pointers
Several functions do not modify pointed data so arguments and local
variables can be const for correctness and safety. This allows also
making file-scope nci_core_get_config_otp_ram_version array const.

power: supply: ab8500: Move to componentized binding
[ Upstream commit 1c1f13a006ed0d71bb5664c8b7e3e77a28da3beb ]
The driver has problems with the different components of
the charging code racing with each other to probe().
This results in all four subdrivers populating battery
information to ascertain that it is populated for their
own needs for example.
Fix this by using component probing and thus expressing
to the kernel that these are dependent components.
The probes can happen in any order and will only acquire
resources such as state container, regulators and
interrupts and initialize the data structures, but no
execution happens until the .bind() callback is called.
The charging driver is the main component and binds
first, then bind in order the three subcomponents:
ab8500-fg, ab8500-btemp and ab8500-chargalg.
Do some housekeeping while we are moving the code around.
Like use devm_* for IRQs so as to cut down on some
boilerplate.

[lld][WebAssembly] Refactor input chunk class hierarchy. NFC
The main motivation for this refactor is to remove the subclass
relationship between the InputSegment and MergeInputSegment and
SyntenticMergedInputSegment so that we can use the merging classes for
debug sections which are not data segments.
In the process of refactoring I also remove all the virtual functions
from the class hierarchy and try to reuse techniques used in the ELF
linker (see `lld/ELF/InputSections.h`).

* config/rs6000/darwin.md: Replace the expanders for
load_macho_picbase and reload_macho_picbase with use of '@'
in their respective define_insns.

commit 13586172d0b70c9d7ca464fc5a2a46a8532b06d7
Author: Martin Jambor <mjambor(a)suse.cz>

ipa: Adjust references to identify read-only globals
this patch has been motivated by SPEC 2017's 544.nab_r in which there is
a static variable which is never written to and so zero throughout the
run-time of the benchmark. However, it is passed by reference to a
function in which it is read and (after some multiplications) passed
into __builtin_exp which in turn unnecessarily consumes almost 10% of
the total benchmark run-time. The situation is illustrated by the added
testcase remref-3.c.
The patch adds a flag to ipa-prop descriptor of each parameter to mark
such parameters. IPA-CP and inling then take the effort to remove
IPA_REF_ADDR references in the caller and only add IPA_REF_LOAD
reference to the clone/overall inlined function. This is sufficient
for subsequent symbol table analysis code to identify the read-only
variable as such and optimize the code.
There are two changes from the RFC version posted to the list earlier.
First, three missing calls to get_base_address were added (there was
another one in an assert). Second, references are not stripped off
the callers if the cloned function cannot change the signature. The
second change reveals a real shortcoming stemming from the fact we
cannot adjust function prototypes with fnspecs. But that is a more
general problem.
gcc/ChangeLog:

* cgraph.h (ipa_replace_map): New field force_load_ref.

(adjust_refs_in_act_callers): New function.
(adjust_references_in_caller): Likewise.
(create_specialized_node): When appropriate, call

dereference, harden testing of call statements.

references a variable.

[ACTIVITY] report week ending 30 July
by Peter Maydell
Progress:
* UM-2 [QEMU upstream maintainership]
+ collected up/reviewed arm patches ready for rc1
+ sent patch fixing a silly crash if the user tried to pass both a
guest kernel and a firmware blob to the raspi3 machine
+ patchset fixing a lot of places in our docs where we used `foo`
in rST markup but we meant ``foo``
+ some docs patches converting old .txt files to .rst so we
actually ship the docs to users
+ patchset doing a bit of cleanup on arch-init.c
+ patches implementing M-profile trap-on-division-by-zero
+ started to look at refactoring the M-profile systick timer to
no longer rely on an ugly global variable to specify the frequency
* QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)]
+ sent out MVE patchset for review which has full coverage of the
instruction set and includes "enable MVE on Cortex-M55"
+ remaining TODO items: fault on unaligned accesses; report MVE
registers via gdbstub; optimize codegen for the no-predication case

commit fedcf3c476aff7533741a1c61071200f0a38cf83
Author: Richard Biener <rguenther(a)suse.de>
Date: Thu Jul 8 09:52:49 2021 +0200
tree-optimization/101373 - avoid PRE across externally throwing call
PRE already tries to avoid hoisting possibly trapping expressions
across calls that might not return normally but fails to consider
const calls that throw externally. The following fixes that and
also plugs the hole of trapping references not pruned in case
they are not catched by the actuall call clobbering it.
At -Os we hit the same issue in RTL PRE and postreload-gcse has
even more incomplete checks so the patch adjusts both of those
as well.
2021-07-08 Richard Biener <rguenther(a)suse.de>
PR tree-optimization/101373
* tree-ssa-pre.c (prune_clobbered_mems): Also prune trapping
references when the BB may not return.
(compute_avail): Pass in the function we're working on and
replace cfun references with it. Externally throwing
const calls also possibly terminate the function.
(pass_pre::execute): Pass down the function we're working on.
* gcse.c (compute_hash_table_work): Externally throwing
const/pure calls also need record_last_mem_set_info.
* postreload-gcse.c (record_opr_changes): Looping or externally
throwing const/pure calls also need record_last_mem_set_info.
* g++.dg/torture/pr101373.C: New testcase, XFAILed.
* gnat.dg/opt95.adb: Likewise.

commit fedcf3c476aff7533741a1c61071200f0a38cf83

tree-optimization/101373 - avoid PRE across externally throwing call
PRE already tries to avoid hoisting possibly trapping expressions
across calls that might not return normally but fails to consider
const calls that throw externally. The following fixes that and
also plugs the hole of trapping references not pruned in case
they are not catched by the actuall call clobbering it.
At -Os we hit the same issue in RTL PRE and postreload-gcse has
even more incomplete checks so the patch adjusts both of those
as well.

PR tree-optimization/101373
* tree-ssa-pre.c (prune_clobbered_mems): Also prune trapping
references when the BB may not return.
(compute_avail): Pass in the function we're working on and
replace cfun references with it. Externally throwing
const calls also possibly terminate the function.
(pass_pre::execute): Pass down the function we're working on.
* gcse.c (compute_hash_table_work): Externally throwing
const/pure calls also need record_last_mem_set_info.
* postreload-gcse.c (record_opr_changes): Looping or externally
throwing const/pure calls also need record_last_mem_set_info.
* g++.dg/torture/pr101373.C: New testcase, XFAILed.
* gnat.dg/opt95.adb: Likewise.

Author: Patrick Palka <ppalka(a)redhat.com>
Date: Thu Jun 3 09:39:13 2021 -0400
c++: cv-qualified dependent name of alias tmpl [PR100592]
Here, the dependent template name in the return type of f() resolves to
an alias of int& after substitution, and we end up complaining about
qualifying this reference type with 'const' from cp_build_qualified_type
rather than just silently dropping the qualification as per [dcl.ref]/1.
The problem is ultimately that make_typename_type ignores the
tf_keep_type_decl flag when the dependent name is a template-id. This
in turn causes the TYPE_DECL check within tsubst <case TYPENAME_TYPE>
to fail, and so we end up not passing tf_ignore_bad_quals to
cp_build_qualified_type. This patch fixes this by making
make_typename_type respect the tf_keep_type_decl flag in this situation.
PR c++/100592
gcc/cp/ChangeLog:
* decl.c (make_typename_type): After calling
lookup_template_class, adjust the result to its TYPE_NAME and
then consider the tf_keep_type_decl flag.

commit d999d9b7e53b9a9cd2004a19e84c637e5e5013f5
Author: Patrick Palka <ppalka(a)redhat.com>

c++: cv-qualified dependent name of alias tmpl [PR100592]
Here, the dependent template name in the return type of f() resolves to
an alias of int& after substitution, and we end up complaining about
qualifying this reference type with 'const' from cp_build_qualified_type
rather than just silently dropping the qualification as per [dcl.ref]/1.
The problem is ultimately that make_typename_type ignores the
tf_keep_type_decl flag when the dependent name is a template-id. This
in turn causes the TYPE_DECL check within tsubst <case TYPENAME_TYPE>
to fail, and so we end up not passing tf_ignore_bad_quals to
cp_build_qualified_type. This patch fixes this by making
make_typename_type respect the tf_keep_type_decl flag in this situation.
PR c++/100592
gcc/cp/ChangeLog:
* decl.c (make_typename_type): After calling
lookup_template_class, adjust the result to its TYPE_NAME and
then consider the tf_keep_type_decl flag.
gcc/testsuite/ChangeLog:
* g++.dg/cpp0x/alias-decl-71.C: New test.

clang-aarch64-quick times out on full build
by Galina Kistanova
Dear Linaro Toolchain Working Group,
https://lab.llvm.org/buildbot/#/builders/clang-aarch64-quick builder hits a
timeout when it builds a clean build. It builds incrementally just fine.
Here is an example - https://lab.llvm.org/buildbot#builders/188/builds/1518
The time out is 20 minutes without any TTY, which looks more than enough.
Could you investigate on what test it gets stuck and what would be a proper
fix, please?
Thanks
Galina

[ACTIVITY] report week ending 23 July
by Peter Maydell
Progress:
* UM-2 [QEMU upstream maintainership]
+ Noticed we didn't enforce the M-profile "low 2 bits of SP are always 0"
rule, and wrote a patch to fix that
+ Found and fixed a handful of other corner-case M-profile bugs
+ Some minor docs improvements
* QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)]
+ Implemented the last 4 instruction patterns (VCVT, VRINT), bringing
us to Progress: 210/210 (100%)
+ Found and fixed a few bugs in already-implemented instructions
+ Started looking at how to make the MVE loads/stores correctly
raise alignment faults for unaligned addresses (this runs into
problems because QEMU doesn't currently have a good API for doing
the load/store the way we want to do it and also handling alignment
faults)
+ Remaining TODO list for this task:
- alignment fault behaviour, if not too difficult
- report MVE registers via the gdbstub (pending on the XML format being
fixed by gdb upstream)
- send out patches for code review

d: RHS value lost when a target_expr modifies LHS in a cond_expr
To prevent the RHS of an assignment modifying the LHS before the
assignment proper, a target_expr is forced so that function calls that
return with slot optimization modify the temporary instead. This did
not work for conditional expressions however, to give one example. So
now the RHS is always forced to a temporary.

Reland "[SCEV] Model ptrtoint(SCEVUnknown) cast not as unknown, but as zext/trunc/self of SCEVUnknown"
This relands commit 1c021c64caef83cccb719c9bf0a2554faa6563af which was
reverted in commit 17cec6a11a12f815052d56a17ef738cf246a2d9a because
an assertion was being triggered, since `BuildConstantFromSCEV()`
wasn't updated to handle the case where the constant we want to truncate
is actually a pointer. I was unsuccessful in coming up with a test case
where we'd end there with constant zext/sext of a pointer,
so i didn't handle those cases there until there is a test case.
Original commit message:
While we indeed can't treat them as no-ops, i believe we can/should
do better than just modelling them as `unknown`. `inttoptr` story
is complicated, but for `ptrtoint`, it seems straight-forward
to model it just as a zext-or-trunc of unknown.
This may be important now that we track towards
making inttoptr/ptrtoint casts not no-op,
and towards preventing folding them into loads/etc

Reland "[SCEV] Model ptrtoint(SCEVUnknown) cast not as unknown, but as zext/trunc/self of SCEVUnknown"
This relands commit 1c021c64caef83cccb719c9bf0a2554faa6563af which was
reverted in commit 17cec6a11a12f815052d56a17ef738cf246a2d9a because
an assertion was being triggered, since `BuildConstantFromSCEV()`
wasn't updated to handle the case where the constant we want to truncate
is actually a pointer. I was unsuccessful in coming up with a test case
where we'd end there with constant zext/sext of a pointer,
so i didn't handle those cases there until there is a test case.
Original commit message:
While we indeed can't treat them as no-ops, i believe we can/should
do better than just modelling them as `unknown`. `inttoptr` story
is complicated, but for `ptrtoint`, it seems straight-forward
to model it just as a zext-or-trunc of unknown.
This may be important now that we track towards
making inttoptr/ptrtoint casts not no-op,
and towards preventing folding them into loads/etc
(see D88979/D88789/D88788)

[LV] Fix scalar cost for tail predicated loops
When it comes to the scalar cost of any predicated block, the loop
vectorizer by default regards this predication as a sign that it is
looking at an if-conversion and divides the scalar cost of the block by
2, assuming it would only be executed half the time. This however makes
no sense if the predication has been introduced to tail predicate the
loop.

[DSE] Improve partial overlap detection
Currently isOverwrite returns OW_MaybePartial even for accesss known not to overlap. This is not a big problem for legacy implementation (since isPartialOverwrite follows isOverwrite and clarifies the result). Contrary SSA based version does a lot of work to later find out that accesses don't overlap. Besides negative impact on compile time we quickly reach MemorySSAPartialStoreLimit and miss optimization opportunities.
Note: In fact, I think it would be cleaner implementation if isOverwrite returned fully clarified result in the first place whithout need to call isPartialOverwrite. This can be done as a follow up. What do you think?

[DSE] Improve partial overlap detection
Currently isOverwrite returns OW_MaybePartial even for accesss known not to overlap. This is not a big problem for legacy implementation (since isPartialOverwrite follows isOverwrite and clarifies the result). Contrary SSA based version does a lot of work to later find out that accesses don't overlap. Besides negative impact on compile time we quickly reach MemorySSAPartialStoreLimit and miss optimization opportunities.
Note: In fact, I think it would be cleaner implementation if isOverwrite returned fully clarified result in the first place whithout need to call isPartialOverwrite. This can be done as a follow up. What do you think?

re PR fortran/88821 (Inline packing of non-contiguous arguments)
2019-05-19 Thomas Koenig <tkoenig(a)gcc.gnu.org>
PR fortran/88821
* expr.c (gfc_is_simply_contiguous): Return true for
an EXPR_ARRAY.
* trans-array.c (is_pointer): New function.
(gfc_conv_array_parameter): Call gfc_conv_subref_array_arg
when not optimizing and not optimizing for size if the formal
arg is passed by reference.
* trans-expr.c (gfc_conv_subref_array_arg): Add arguments
fsym, proc_name and sym. Add run-time warning for temporary
array creation. Wrap argument if passing on an optional
argument to an optional argument.
* trans.h (gfc_conv_subref_array_arg): Add optional arguments
fsym, proc_name and sym to prototype.

Re: [CI-NOTIFY]: TCWG Bisect tcwg_kernel/llvm-release-arm-next-allyesconfig - Build # 13 - Successful!
by Maxim Kuvyrkov
Hi Alexey,
Your patch appears to break build on aarch64 and arm in allmodconfig and allyesconfig configurations.
Would you please investigate? Please let us know if it doesn't easily reproduce for you.
Thanks!

commit 6f4266a78a4e090b452a0335c1414f3240684743
Author: Alexey Dobriyan <adobriyan(a)gmail.com>

kbuild: decouple build from userspace headers
First, userspace headers can be under incompatible license.
Second, kernel doesn't require userspace to operate and should not
require anything from userspace to be built other than compiler.
We would use -ffreestanding too if not builtin function shenanigans.
To decouple:
* ship minimal stdarg.h as <linux/stdarg.h>,
1 type, 4 macros
GPL 2 version of <stdarg.h> can be extracted from
http://archive.debian.org/debian/pool/main/g/gcc-4.2/gcc-4.2_4.2.4.orig.tar…
* delete "-isystem" from command line arguments,
this is what enables header leakage
* fixup/delete include directives where necessary.

Reland "[SCEV] Model ptrtoint(SCEVUnknown) cast not as unknown, but as zext/trunc/self of SCEVUnknown"
This relands commit 1c021c64caef83cccb719c9bf0a2554faa6563af which was
reverted in commit 17cec6a11a12f815052d56a17ef738cf246a2d9a because
an assertion was being triggered, since `BuildConstantFromSCEV()`
wasn't updated to handle the case where the constant we want to truncate
is actually a pointer. I was unsuccessful in coming up with a test case
where we'd end there with constant zext/sext of a pointer,
so i didn't handle those cases there until there is a test case.
Original commit message:
While we indeed can't treat them as no-ops, i believe we can/should
do better than just modelling them as `unknown`. `inttoptr` story
is complicated, but for `ptrtoint`, it seems straight-forward
to model it just as a zext-or-trunc of unknown.
This may be important now that we track towards
making inttoptr/ptrtoint casts not no-op,
and towards preventing folding them into loads/etc

New IRC Channel for Linaro Toolchain Working Group
by Matthew Gretton-Dann
All,
During Connect the suggestion was made that each working group should have
its own IRC Channel for discussions and topics relating to the group in
particular (as opposed to #linaro which is 'generic' Linaro conversations).
Therefore I have just set up #linaro-tcwg on Freenode for the Toolchain
Working Group.
This channel is public and open to anyone who wants to talk with the TCWG
group about anything toolchain related.
Thanks,
Matt

[ACTIVITY] report week ending 16 Jul
by Peter Maydell
Progress:
* UM-2 [QEMU upstream maintainership]
+ Code review:
- ITS patchset v6
- RTH's series to allow usermode emulation users to set default vector length
+ Arm pullreq; shepherding stuff in for softfreeze
* QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)]
+ Sent out patchset with the 3rd slice of MVE insns; I now have
all the non-floating-point insns done, I think. New insns:
scatter-gather loads/stores, interleaving loads/stores, VCTP,
realized I already did VMOVL as it is "VSHLL-by-0"
+ Implemented most of the floating point insns: implemented
VADD fp, VSUB fp, VABD fp, VMUL fp, VMAXNM, VMINNM, VCADD fp,
VFMA, VFMS, VCMUL, VCMLA, VMAXNMA, VMINNMA, VADD fp scalar,
VSUB fp scalar, VMUL fp scalar, VFMA fp scalar, VFMAS fp scalar,
VMAXNMV, VMAXNMAV, VMINNMV, VMINNMAV, VCMP and VPT fp vector and scalar,
VCVT fixed-point
+ Just 4 insns to go: three flavours of VCVT, plus VRINT (and then
all the other stuff that wasn't included in this simplistic
measure of progress :-))
+ Progress: 206/210 (98%)

commit c7207339a7dbce5b68f872064e624dcf1639ba46
Author: Wilco Dijkstra <wdijkstr(a)arm.com>

[ARM] Switch to default sched pressure algorithm
Currently the Arm backend selects the alternative sched pressure algorithm.
The issue is that this doesn't take register pressure into account, and so
it causes significant additional spilling on Arm where there are only 14
allocatable registers. Building SPEC2006 showed significant codesize gains
with the default pressure algorithm, so switch back to that. PR77308 shows
~800 fewer instructions.
SPECINT2006 is ~0.6% faster on Cortex-A57 together with the other DImode
patches. Overall SPEC codesize is 1.1% smaller.

[ARM] Switch to default sched pressure algorithm
Currently the Arm backend selects the alternative sched pressure algorithm.
The issue is that this doesn't take register pressure into account, and so
it causes significant additional spilling on Arm where there are only 14
allocatable registers. Building SPEC2006 showed significant codesize gains
with the default pressure algorithm, so switch back to that. PR77308 shows
~800 fewer instructions.
SPECINT2006 is ~0.6% faster on Cortex-A57 together with the other DImode
patches. Overall SPEC codesize is 1.1% smaller.

tree-optimization/101373 - avoid PRE across externally throwing call
PRE already tries to avoid hoisting possibly trapping expressions
across calls that might not return normally but fails to consider
const calls that throw externally. The following fixes that and
also plugs the hole of trapping references not pruned in case
they are not catched by the actuall call clobbering it.
At -Os we hit the same issue in RTL PRE and postreload-gcse has
even more incomplete checks so the patch adjusts both of those
as well.

Remove global call sets: gcse.c
This is another case in which we can conservatively treat partial
kills as full kills. Again this is in principle a bug fix for
TARGET_HARD_REGNO_CALL_PART_CLOBBERED targets, but in practice
it probably doesn't make a difference.

elf: Call free from base namespace on error in dl-libc.c [BZ #27646]
In dlerror_run, free corresponds to the local malloc in the
namespace, but GLRO (dl_catch_error) uses the malloc from the base
namespace. elf/tst-dlmopen-gethostbyname triggers this mismatch,
but it does not crash, presumably because of a fastbin deallocation.
Fixes commit c2059edce20c124d1a99f1a94cc52e83b77a917a ("elf: Use
_dl_catch_error from base namespace in dl-libc.c [BZ #27646]") and
commit b2964eb1d9a6b8ab1250e8a881cf406182da5875 ("dlfcn: Failures
after dlmopen should not terminate process [BZ #24772]").

[SLP] Control maximum vectorization factor from TTI
D82227 has added a proper check to limit PHI vectorization to the
maximum vector register size. That unfortunately resulted in at
least a couple of regressions on SystemZ and x86.
This change reverts PHI handling from D82227 and replaces it with
a more general check in SLPVectorizerPass::tryToVectorizeList().
Moved to tryToVectorizeList() it allows to restart vectorization
if initial chunk fails.
However, this function is more general and handles not only PHI
but everything which SLP handles. If vectorization factor would
be limited to maximum vector register size it would limit much
more vectorization than before leading to further regressions.
Therefore a new TTI callback getMaximumVF() is added with the
default 0 to preserve current behavior and limit nothing. Then
targets can decide what is better for them.
The callback gets ElementSize just like a similar getMinimumVF()
function and the main opcode of the chain. The latter is to avoid
regressions at least on the AMDGPU. We can have loads and stores
up to 128 bit wide, and <2 x 16> bit vector math on some
subtargets, where the rest shall not be vectorized. I.e. we need
to differentiate based on the element size and operation itself.

commit b46cfcef3f7dab8e90729c6616ac1420f2642245
Author: Joseph Myers <joseph(a)codesourcery.com>
Date: Wed Jul 7 13:24:05 2021 +0000
Update kernel version to 5.13 in tst-mman-consts.py
This patch updates the kernel version in the test tst-mman-consts.py
to 5.13. (There are no new MAP_* constants covered by this test in
5.13 that need any other header changes.)
Tested with build-many-glibcs.py.

Update kernel version to 5.13 in tst-mman-consts.py
This patch updates the kernel version in the test tst-mman-consts.py
to 5.13. (There are no new MAP_* constants covered by this test in
5.13 that need any other header changes.)
Tested with build-many-glibcs.py.

commit cd76f43b4995cf01bae9f97a54ca0e79c2355032
Author: David Green <david.green(a)arm.com>
Date: Wed Jun 30 19:19:03 2021 +0100
[ARM] Set the immediate cost of GEP operands to 0
This prevents constant gep operands from being hoisted by the Constant
Hoisting pass, leaving them to CodegenPrepare which can usually do a
better job at splitting large offsets. This can, in general, improve
performance and decrease codesize, especially for v6m where many
constants have a high cost.

elf: Clean up GLIBC_PRIVATE exports of internal libdl symbols
They are no longer needed after everything has been moved into
libc. The _dl_vsym test has to be removed because the symbol
cannot be used outside libc anymore.

elf: Clean up GLIBC_PRIVATE exports of internal libdl symbols
They are no longer needed after everything has been moved into
libc. The _dl_vsym test has to be removed because the symbol
cannot be used outside libc anymore.

nptl: Use internal low-level lock type for !IS_IN (libc)
This avoids an ABI hazard (types changing between different modules
of glibc) without introducing linknamespace issues. In particular,
NSS modules now call __lll_lock_wait_private@@GLIBC_PRIVATE to wait
on internal locks (the unlock path is inlined and performs a direct
system call).

glibc.malloc.check: Fix nit in documentation
The tunable will not work with *any* non-zero tunable value since its
list of allowed values is 0-3. Fix the documentation to reflect that.

Exclude tst-realloc from tests-mcheck
The realloc (NULL, 0) test in tst-realloc fails with gcc 7.x but
passes with newer gcc. This is because a newer gcc transforms the
realloc call to malloc (0), thus masking the bug in mcheck.
Disable the test with mcheck for now. The malloc removal patchset
will fix this and then remove this test from the exclusion list.

linux: Consolidate Linux setsockopt implementation
This patch consolidates the setsockopt implementation on
sysdeps/unix/sysv/linux/getsockopt.c. The changes are:
1. Remove it from auto-generation syscalls.list on all architectures.
2. Add __ASSUME_SETSOCKOPT_SYSCALL as default and undef if for
specific kernel versions on some architectures.
This also fix a potential issue where 32-bit time_t ABI should use the
linux setsockopt which overrides the underlying SO_* constants used for
socket timestamping for _TIME_BITS=64.
Checked on x86_64-linux-gnu and i686-linux-gnu.

linux: Consolidate Linux getsockopt implementation
This patch consolidates the getsockopt Linux syscall implementation on
sysdeps/unix/sysv/linux/getsockopt.c. The changes are:
1. Remove it from auto-generation syscalls.list on all architectures.
2. Add __ASSUME_GETSOCKOPT_SYSCALL as default and undef if for
specific kernel versions on some architectures.
This also fix a potential issue where 32-bit time_t ABI should use the
linux getsockopt which overrides the underlying SO_* constants used for
socket timestamping for _TIME_BITS=64.
Checked on x86_64-linux-gnu and i686-linux-gnu.

This function is similar to the @code{readv} function, with the difference
it adds an extra @var{offset} parameter of type @code{off_t} similar to
