Mikhail Maltsev 47edf5bafb [ARM,CDE] Generalize MVE intrinsics infrastructure to support CDE
Summary:
This patch generalizes the existing code to support CDE intrinsics
which will share some properties with existing MVE intrinsics
(some of the intrinsics will be polymorphic and accept/return values
of MVE vector types).
Specifically the patch:
* Adds new tablegen backends -gen-arm-cde-builtin-def,
  -gen-arm-cde-builtin-codegen, -gen-arm-cde-builtin-sema,
  -gen-arm-cde-builtin-aliases, -gen-arm-cde-builtin-header based on
  existing MVE backends.
* Renames the '__clang_arm_mve_alias' attribute into
  '__clang_arm_builtin_alias' (it will be used with CDE intrinsics as
  well as MVE intrinsics)
* Implements semantic checks for the coprocessor argument of the CDE
  intrinsics as well as the existing coprocessor intrinsics.
* Adds one CDE intrinsic __arm_cx1 to test the above changes

Jonas Paulsson c2dafe12dc [SimplifyCFG] Skip merging return blocks if it would break a CallBr.
SimplifyCFG should not merge empty return blocks and leave a CallBr behind
with a duplicated destination since the verifier will then trigger an
assert. This patch checks for this case and avoids the transformation.

CodeGenPrepare has a similar check which also has a FIXME comment about why
this is needed. It seems perhaps better if these two passes would eventually
instead update the CallBr instruction instead of just checking and avoiding.

This fixes https://bugs.llvm.org/show_bug.cgi?id=45062.

Florian Hahn 2d6ecf4648 [SLP] Support vectorizing functions provided by vector libs.
It seems like the SLPVectorizer is currently not aware of vector
versions of functions provided by libraries like Accelerate [1].
This patch updates SLPVectorizer to use the same infrastructure
the LoopVectorizer uses to detect vectorizable library functions.

For calls, it computes the cost of an intrinsic call (existing behavior)
and the cost of a vector function library call, if available. Like
LoopVectorizer, it assumes the cost of the vector function is simply the
cost of a call to a vector function.

selected by command line switches). This patch creates a separate

Pavel Labath d00dff88b4 [lldb] Make UnwindLLDB a non-plugin
Summary:
This is the only real unwinder, and things have been this way for quite
a long time. At this point, the class has accumulated so many features
it is unlikely that anyone will want to reimplement the whole thing.

The class is also fairly closely coupled (through UnwindPlans and
FuncUnwinders) with a lot of other lldb components that it is hard to
imagine a different unwinder implementation being substantially
different without reimplementing all of those.

The existing unwinding functionality is nonetheless fairly complex and
there is space for adding more structure to it, but I believe a more
worthwhile effort would be to take the existing UnwindLLDB class and try
to break it down and introduce extension/customization points, instead
of writing a brand new Unwind implementation.

alex-t 39e1a90784 [AMDGPU] SI_INDIRECT_DST_V* pseudos expansion should place EXEC restore to separate basic block
Summary:
When SI_INDIRECT_DST_V* pseudos has indexes in VGPR, they get expanded into the self-looped basic block that modifies EXEC in a loop.

To keep EXEC consistent it is stored before and then re-stored after the pseudo expansion result.

%95:vreg_512 = SI_INDIRECT_DST_V16 %93:vreg_512(tied-def 0), %94:sreg_32, 0, killed %1500:vgpr_32

results to

    s_mov_b64 s[6:7], exec
BB0_16:
    v_readfirstlane_b32 s8, v28
    v_cmp_eq_u32_e32 vcc, s8, v28
    s_and_saveexec_b64 vcc, vcc
    s_set_gpr_idx_on s8, gpr_idx(DST)
    v_mov_b32_e32 v6, v25

    s_xor_b64 exec, exec, vcc
    s_cbranch_execnz BB0_16
; %bb.17:
    s_mov_b64 exec, s[6:7]

The bug appeared in case this expansion occurs in the ELSE block of the CF.

Originally

  %110:vreg_512 = SI_INDIRECT_DST_V16 %103:vreg_512(tied-def 0), %85:vgpr_32, 0, %107:vgpr_32,
   %112:sreg_64 = SI_ELSE %108:sreg_64, %bb.19, 0, implicit-def dead $exec, implicit-def dead $scc, implicit $exec

expanded to

         ******************   <== here exec has "THEN" context

    s_mov_b64 s[6:7], exec
BB0_16:
    v_readfirstlane_b32 s8, v28
    v_cmp_eq_u32_e32 vcc, s8, v28
    s_and_saveexec_b64 vcc, vcc
    s_set_gpr_idx_on s8, gpr_idx(DST)
    v_mov_b32_e32 v6, v25
    s_set_gpr_idx_off
    s_xor_b64 exec, exec, vcc
    s_cbranch_execnz BB0_16
; %bb.17:
    s_or_saveexec_b64 s[4:5], s[4:5]   <-- exec mask is restored for "ELSE" but immediately overwritten.
    s_mov_b64 exec, s[6:7]

The rest of the "ELSE" block is executed not by the workitems which constitute the "else mask" but by those which constitute "then mask"

SILowerControlFlow::emitElse always considers the basic block begin() as an insertion point for s_or_saveexec.

Proposed fix:  The SI_INDIRECT_DST_V* procedure should split the reminder block to create landing pad for the EXEC restoration.

For pre-AVX512 targets, combine binary shuffles to X86ISD::VPERM2X128 if possible. This mainly helps optimize the blend(extract_subvector(x,1),y) pattern.

At some point soon we're going to have make a decision about when to combine AVX512 shuffles more aggressively - we bail out if there is any change in element size (to protect predicate mask merging) which means we miss out on a lot of optimizations.

Sam Parker ff9ac33e1e [ARM][MVE] Validate tail predication values
Iterate through the loop and check that the observable values
produced are the same whether tail predication happens or not.

We want to find out if the tail-predicated version of this loop will
produce the same values as the loop in its original form. For this to
be true, the newly inserted implicit predication must not change the
the (observable) results.

We're doing this because many instructions in the loop will not be
predicated and so the conversion from VPT predication to tail
predication can result in different values being produced, because of
falsely predicated lanes not being updated in the converted form.

A masked load, whether through VPT or tail predication, will write
zeros to any of the falsely predicated bytes. So, from the loads, we
know that the false lanes are zeroed and here we're trying to track
that those false lanes remain zero, or where they change, the
differences are masked away by their user(s).

All MVE loads and stores have to be predicated, so we know that any
load operands, or stored results are equivalent already. Other
explicitly predicated instructions will perform the same operation in
the original loop and the tail-predicated form too. Because of this,
we can insert loads, stores and other predicated instructions into
our KnownFalseZeros set and build from there.

We previously assumed they were neither value- nor

This doesn't match GCC's behavior (where statement expressions appear to
be treated as value-dependent if they appear in a dependent context),
but seems to be the best thing we can do in the short term: it turns out
to be remarkably difficult for us to correctly determine whether we are
in a dependent context (and it's not even possible in some cases, such
as in a generic lambda where we might not have seen the 'auto' yet).

This was previously reverted in 8e4a867 for rejecting some code, but that
code was invalid and Clang was previously incorrectly accepting it.

River Riddle b10c662514 [mlir][SideEffects] Replace the old SideEffects dialect interface with the newly added op interfaces/traits.
Summary:
The old interface was a temporary stopgap to allow for implementing simple LICM that took side effects of region operations into account. Now that MLIR has proper support for specifying memory effects, this interface can be deleted.

George Burgess IV cfc3e7f458 [cmake] Strip quotes in compiler-rt/lib/crt; error if checks fail
Patch by Zhizhou Yang!

In his own words:

"""
Similar change to CMakeLists as r372312.

After r372209, compiler command line may include argument with quotes:

```
-fprofile-instr-use="/foo/bar.profdata"
```

And it causes a hidden failure with execute_process later: Could not
read profile "/foo/bar.profdata": No such file or directory.

In this particular case, the check for .init_array will fail silently
and creates a PGO-ed binary with bad .init_array section in compiler-rt.

Bug details can be found in PR45022
