[Fuzzer][Test] Use %python substitution for trace-malloc-unbalanced.test
This test was found to fail for some of our downstream builds, on
computers where python was not on the default $PATH. Therefore
add a %python substitution to use sys.executable, based on similar
solutions for python calls in tests elsewhere in LLVM.

[ACTIVITY] report week ending 20 Aug
by Peter Maydell
Progress:
* UM-2 [QEMU upstream maintainership]
+ We needed an rc4 (as usual)
+ Tried to work through some of my code review patchlog, notably
some big alignment-related series from RTH
+ Sent patchseries for some small things:
+ implement last few bits of HSTR trap-to-hypervisor functionality
+ actually take an exception if PSTATE.IL gets set
+ don't assert if user asks for both an EL3 guest CPU and KVM
* QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)]
+ worked through rth's code review comments for fp insn patches
these are now ready to send out once QEMU makes its 6.1 release
and the previous slice of reviewed patches can get into the tree

commit a838a4f69f500fc8e39fb4c9a1476f162ccf8423
Author: David Green <david.green(a)arm.com>
Date: Mon Feb 15 13:17:21 2021 +0000
[ARM] Extend search for increment in load/store optimizer
Currently the findIncDecAfter will only look at the next instruction for
post-inc candidates in the load/store optimizer. This extends that to a
search through the current BB, until an instruction that modifies or
uses the increment reg is found. This allows more post-inc load/stores
and ldm/stm's to be created, especially in cases where a schedule might
move instructions further apart.
We make sure not to look any further for an SP, as that might invalidate
stack slots that are still in use.

[ARM] Extend search for increment in load/store optimizer
Currently the findIncDecAfter will only look at the next instruction for
post-inc candidates in the load/store optimizer. This extends that to a
search through the current BB, until an instruction that modifies or
uses the increment reg is found. This allows more post-inc load/stores
and ldm/stm's to be created, especially in cases where a schedule might
move instructions further apart.
We make sure not to look any further for an SP, as that might invalidate
stack slots that are still in use.

commit cedfa38fc46d7531c44ea230b767d8286767f350
Author: Jin Lin <jinl(a)uber.com>
Date: Fri Apr 23 22:37:08 2021 -0700
Preserve the lexical order for global variables during llvm-link merge
The order of global variables is generated in the order of recursively materializing variables if the global variable has the attribute of hasLocalLinkage or hasLinkOnceLinkage during the module merging. In practice, it is often the exact reverse of source order. This new order may cause performance regression.
The change is to preserve the original lexical order for global variables.

Preserve the lexical order for global variables during llvm-link merge
The order of global variables is generated in the order of recursively materializing variables if the global variable has the attribute of hasLocalLinkage or hasLinkOnceLinkage during the module merging. In practice, it is often the exact reverse of source order. This new order may cause performance regression.
The change is to preserve the original lexical order for global variables.

commit 34eb0adaa9cd76f5bb0549f5a32d6ef452fe977e

[flang] Add -fsyntax-only to f18; retain -fparse-only synonym
Now that semantics is working, the standard -fsyntax-only option of
GNU and Clang should be used as the name of the option that causes
f18 to just run the front-end. Support both options in f18, silently
accepting the old option as a synonym for the new one (as
preferred by the code owner), and replace all instances of the
old -fparse-only option with -fsyntax-only throughout the source base.

[SampleFDO][NFC] Refactor SampleProfile.cpp
Refactor SampleProfile.cpp to use the core code in CodeGen.
The main changes are:
(1) Move SampleProfileLoaderBaseImpl class to a header file.
(2) Split SampleCoverageTracker to a head file and a cpp file.
(3) Move the common codes (common options and callsiteIsHot())
to the common cpp file.

+/// Generate branch weight metadata for all branches in \p F.
+///
+/// Branch weights are computed out of instruction samples using a
+/// propagation heuristic. Propagation proceeds in 3 phases:
+///
+/// 1- Assignment of block weights. All the basic blocks in the function
+/// are initial assigned the same weight as their most frequently
+/// executed instruction.
+///
+/// 2- Creation of equivalence classes. Since samples may be missing from
+/// blocks, we can fill in the gaps by setting the weights of all the
+/// blocks in the same equivalence class to the same weight. To compute
+/// the concept of equivalence, we use dominance and loop information.
+/// Two blocks B1 and B2 are in the same equivalence class if B1
+/// dominates B2, B2 post-dominates B1 and both are in the same loop.
+///
+/// 3- Propagation of block weights into edges. This uses a simple
+/// propagation heuristic. The following rules are applied to every
+/// block BB in the CFG:
+///
+/// - If BB has a single predecessor/successor, then the weight
+/// of that edge is the weight of the block.
+///
+/// - If all the edges are known except one, and the weight of the
+/// block is already known, the weight of the unknown edge will
+/// be the weight of the block minus the sum of all the known
+/// edges. If the sum of all the known edges is larger than BB's weight,
+/// we set the unknown edge weight to zero.
+///
+/// - If there is a self-referential edge, and the weight of the block is
+/// known, the weight for that edge is set to the weight of the block
+/// minus the weight of the other incoming edges to that block (if
+/// known).
+///
+/// Since this propagation is not guaranteed to finalize for every CFG, we
+/// only allow it to proceed for a limited number of iterations (controlled
+/// by -sample-profile-max-propagate-iterations).
+///
+/// FIXME: Try to replace this propagation heuristic with a scheme
+/// that is guaranteed to finalize. A work-list approach similar to
+/// the standard value propagation algorithm used by SSA-CCP might
+/// work here.
+///
+/// \param F The function to query.

[InstCombine] avoid breaking up min/max (cmp+sel) idioms
This is a quick fix for a motivating case that looks like this:

As noted, we might be able to restore the min/max patterns

commit dae7adda949993bd96aa50c551dc64ddebba7923
Author: Matt Jacobson <mhjacobson(a)me.com>
Date: Fri Aug 6 10:12:00 2021 +0800
[AVR][clang] Pass '-fno-use-init-array' to cc1 as default
On AVR, '.ctors' is used, not '.init_array'. Make this the default
unless specifically overridden by driver argument.
This matches gcc, and it matches the behavior in (e.g.) the NetBSD
driver (for certain OS variants).

Date: Fri Aug 6 10:12:00 2021 +0800
[AVR][clang] Pass '-fno-use-init-array' to cc1 as default
On AVR, '.ctors' is used, not '.init_array'. Make this the default
unless specifically overridden by driver argument.
This matches gcc, and it matches the behavior in (e.g.) the NetBSD
driver (for certain OS variants).

[LoopVectorize] Simplify scalar cost calculation in getInstructionCost
This patch simplifies the calculation of certain costs in
getInstructionCost when isScalarAfterVectorization() returns a true value.
There are a few places where we multiply a cost by a number N, i.e.
unsigned N = isScalarAfterVectorization(I, VF) ? VF.getKnownMinValue() : 1;
return N * TTI.getArithmeticInstrCost(...
After some investigation it seems that there are only these cases that occur
in practice:
1. VF is a scalar, in which case N = 1.
2. VF is a vector. We can only get here if: a) the instruction is a
GEP/bitcast/PHI with scalar uses, or b) this is an update to an induction
variable that remains scalar.
I have changed the code so that N is assumed to always be 1. For GEPs
the cost is always 0, since this is calculated later on as part of the
load/store cost. PHI nodes are costed separately and were never previously
multiplied by VF. For all other cases I have added an assert that none of
the users needs scalarising, which didn't fire in any unit tests.
Only one test required fixing and I believe the original cost for the scalar
add instruction to have been wrong, since only one copy remains after
vectorisation.
I have also added a new test for the case when a pointer PHI feeds directly
into a store that will be scalarised as we were previously never testing it.

[clang] Remove misleading assertion in FullSourceLoc
D31709 added an assertion was added to `FullSourceLoc::hasManager()` that ensured a valid `SourceLocation` is always paired with a `SourceManager`, and missing `SourceManager` is always paired with an invalid `SourceLocation`.
This appears to be incorrect, since clients never cared about constructing `FullSourceLoc` to uphold that invariant, or always checking `isValid()` before calling `hasManager()`.
The assertion started failing when serializing diagnostics pointing into an explicit module. Explicit modules don't have valid `SourceLocation` for the `import` statement, since they are "imported" from the command-line argument `-fmodule-name=x.pcm`.
This patch removes the assertion, since `FullSourceLoc` was never intended to uphold any kind of invariants between the validity of `SourceLocation` and presence of `SourceManager`.

[ARM] Change getScalarizationOverhead overload used in gather costs. NFC
This changes which of the getScalarizationOverhead overloads is used in
the gather/scatter cost to use the base variant directly, not relying on
the version using heuristics on the number of args with no args
provided. It should still produce the same costs for scalarized
gathers/scatters.

* ``strict`` Enables ``-frounding-math`` and ``-ffp-exception-behavior=strict``, and disables contractions (FMA). All of the ``-ffast-math`` enablements are disabled. Enables ``STDC FENV_ACCESS``: by default ``FENV_ACCESS`` is disabled. This option setting behaves as though ``#pragma STDC FENV_ACESS ON`` appeared at the top of the source file.

Turn on the new pass manager by default
This turns on the new pass manager by default for the optimization pipeline in
Clang and ThinLTO in various LLD backends. This also makes uses of `opt
-instcombine` use the new pass manager (unless specifically opted out).
This does not affect the backend target-dependent codegen pipeline.
If this causes regressions, you can opt out of the new pass manager
either via the -DENABLE_EXPERIMENTAL_NEW_PASS_MANAGER=OFF CMake flag
while building LLVM, or via various compiler flags, e.g.
-flegacy-pass-manager for Clang or -Wl,--lto-legacy-pass-manager for
ELF LLD. Please file bugs for any regressions.
Major differences:
* The inliner works slightly differently
* -O1 does some amount of inlining
* LCSSA and LoopSimplify are run before all loop passes
* Loop unswitching is implemented slightly differently
* A new SpeculateAroundPHIs pass is added to the pipeline

commit 669ddd1e9b1226432b003dbba05b99f8e992285b
Author: Arthur Eubanks <aeubanks(a)google.com>

Turn on the new pass manager by default
This turns on the new pass manager by default for the optimization pipeline in
Clang and ThinLTO in various LLD backends. This also makes uses of `opt
-instcombine` use the new pass manager (unless specifically opted out).
This does not affect the backend target-dependent codegen pipeline.
If this causes regressions, you can opt out of the new pass manager
either via the -DENABLE_EXPERIMENTAL_NEW_PASS_MANAGER=OFF CMake flag
while building LLVM, or via various compiler flags, e.g.
-flegacy-pass-manager for Clang or -Wl,--lto-legacy-pass-manager for
ELF LLD. Please file bugs for any regressions.
Major differences:
* The inliner works slightly differently
* -O1 does some amount of inlining
* LCSSA and LoopSimplify are run before all loop passes
* Loop unswitching is implemented slightly differently
* A new SpeculateAroundPHIs pass is added to the pipeline
