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

* 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.

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

[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?

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!

> 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.

commit 6f4266a78a4e090b452a0335c1414f3240684743
Author: Alexey Dobriyan <adobriyan(a)gmail.com>
Date: Fri Jul 16 13:44:03 2021 +1000
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.

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.

commit 1fb610429308a7c29c5065f5cc35dcc3fd69c8b1
Author: Roman Lebedev <lebedev.ri(a)gmail.com>
Date: Mon Oct 12 22:19:17 2020 +0300
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)

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)

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%)

[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

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.

[CI-NOTIFY]: TCWG Bisect tcwg_bmk_tx1/gnu-release-aarch64-spec2k6-O2 - Build # 15 - Successful!

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.

commit 832f50be6c9c010e46180d14126bbb81f35e808c
Author: Florian Weimer <fweimer(a)redhat.com>
Date: Tue Jul 6 13:22:01 2021 +0200
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.

Author: David Green <david.green(a)arm.com>

[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.

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).

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

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.
