The .yaml files should live next to the corresponding .h.def
files in libc/include/, rather than next to the implementation of
the tool in libc/utils/hdrgen/. As with the .h.def files, there
is no need for a yaml/ subdirectory under include/. This simpler
layout is more natural for maintenance and also simplifies build
integration outside the LLVM CMake build.
Move replacement of VPBBs for vector preheader, middle block and scalar
preheader from VPlan::execute to skeleton creation, which actually
creates the IR basic blocks.
For now, the vector preheader can only be replaced after
prepareToExecute as it may create new instructions in the vector
preheader.
The problem in original change is because OHOS::getCompilerRT()
pickes a wrong builtin runtime
`./lib/clang/20/lib/linux/libclang_rt.builtins-x86_64.a`,
if `./lib/clang/20/lib/linux/libclang_rt.builtins-x86_64.a` exist on the
test filesystem. It shouldn't happen with a clean build.
This reverts commit b8952d4b1b.
spec x264 fails to build in all VLS configurations, with the assertion
failure: clang: ../llvm-project/llvm/lib/Target/RISCV/RISCVISelLowering.cpp:5246: llvm::SDValue lowerShuffleViaVRegSplitting(llvm::ShuffleVectorSDNode*, llvm::SelectionDAG&, const llvm::RISCVSubtarget&): Assertion `RegCnt == NumOfDestRegs && "Whole vector must be processed"' failed.
I can reduce a failing piece of IR, but the failure appears pretty
broad, so I suspect any reasonable vls build will hit it.
The addFile implementation does not rely on the SymbolTable object. With
#119294, the symbol table for input files is determined during the
construction of the objects representing them. To clarify that
relationship, this change moves the implementation from the SymbolTable
class to the LinkerDriver class.
This patch does following things,
- prefer early exits;
- add missing std::move;
- avoid duplicate map lookups;
- prefer emplace_back to avoid unnecessary copies.
- Add `llvm-xray account` regression test for an exit mismatch with a
non empty stack (its a different code path than empty stack).
- Align empty stack test case name.
Prepend mlir's include directories before system LLVM include
directories. This is particularly important for standalone builds, where
system include directory may contain the previous version of mlir, and
therefore various mlir targets (particularly tablegen) end up using the
headers from the previous version over the fresh ones. The new logic is
copied from clang.
`LIU::Matrix` holds on to a pointer to the allocator in LiveRegMatrix and is left hanging when the allocator moves with the LiveRegMatrix.
This extends the lifetime of the allocator so that it does not get destroyed when moving a LiveRegMatrix object.
This fixes#117438.
If paths in dependency file are not absoulte, make (or ninja) will
canonicalize them.
While their canonicalization does not involves symbolic links expansion
(for IO performance concerns), leaving a non-absolute path in dependency
file may lead to unexpected canonicalization.
For example, '/a/../b', where '/a' is a symlink to '/c/d', it should be
'/c/b' but make (and ninja) canonicalizes it as '/b', and fails for file
not found.
On RISC-V, AArch64, and LoongArch, the `_mcount` function takes
`__builtin_return_address(0)` as an argument since
`__builtin_return_address(1)` is not available on these platforms. This
patch fixes the argument passing to match the behavior of glibc/gcc.

The SelectionDAG Isel supports the both version of combines mentioned
below :
```
select Cond, Pow2, 0 --> (zext Cond) << log2(Pow2)
select Cond, 0, Pow2 --> (zext !Cond) << log2(Pow2)
```
The GlobalIsel for now only supports the first one defined in it's
generic combinerHelper.cpp. This patch adds the missing second one.
Add missing test coverage of loops where the vector loop region can be
removed that include replicate recipes as well as nested loops.
Extra test coverage for https://github.com/llvm/llvm-project/pull/108378.
This ensures that all blocks created during VPlan execution are properly
added to an enclosing loop, if present.
Split off from https://github.com/llvm/llvm-project/pull/108378 and also
needed once more of the skeleton blocks are created directly via VPlan.
This also allows removing the custom logic for early-exit loop
vectorization added as part of
https://github.com/llvm/llvm-project/pull/117008.
I believe these are usually canonicalized to vector extracts in most
situations, but under -O0 we might trigger failures in the widening code
if we do not handle scalar destinations correctly. The simplest solution
should be to lower the shuffle to an extract.
Fixes#121365.
The Intel Darwin CI bots had their Xcode updated, which brought in a
debugserver with Brendan Shanks' change from September
7281e0cb3bhttps://github.com/llvm/llvm-project/pull/108663 where four general
purpose registers are sent by debugserver when in certain process
states. But most processes (nearly all in the testsuite) do not have
these registers available, so we will get register read failures when
requesting those four. These two tests would flag those as errors. There
would have been an additional problem with the g/G packet (which lldb
doesn't use w/ debugserver, but the testsuite tests) if placeholder
values were not included in the full register context bytes; I fixed
that issue with the SME patch to debugserver recently already.
BusyBox `cat` has yet another slight variation of error formatting:
```console
$ cat --help 2>&1 | head -1
BusyBox v1.37.0 (2024-09-30 10:39:57 UTC) multi-call binary.
$ cat does-not-exist
cat: can't open 'does-not-exist': No such file or directory
```
Rather than extend the test result regex with a third case,
recognise that we only really care about the filename and errno string.
Weaken the regex to ignore all "noise" around the filename.
Note this also corrects what looks like a bug with the previous regex.
Previously, the `cannot open does-not-exist` alternate did not assert
the following errno message. This was introduced in
https://reviews.llvm.org/D60553 (apparently) due to differences in the
`cat` command on AIX. That bug doesn't include the specific
AIX output, so it's unclear if this omission was intended.
`-passes='default<O3>'` isn't correctly parsed on DOS, so when update_test_checks.py runs a system call on the opt RUN line, it fails to evaluate properly - use `-passes="default<O3>"` instead.
This patch makes sure YAML files are opened for reading as text file to
trigger auto-conversion from EBCDIC encoding into expected ASCII
encoding on z/OS platform. This is required to fix the following lit
tests:
```
LLVM :: tools/llvm-gsymutil/ARM_AArch64/macho-gsym-callsite-info-exe.yaml
LLVM :: tools/llvm-gsymutil/ARM_AArch64/macho-gsym-callsite-info-obj.test
LLVM :: tools/llvm-gsymutil/ARM_AArch64/macho-gsym-callsite-info-dsym.yaml
LLVM :: Transforms/PGOProfile/memprof_undrift_missing_leaf.ll
```
When `collectFromBlock` is called without a predecessor (in particular
for loops that don't have a unique predecessor outside the loop) we
never start climbing the predecessor chain, and thus don't mark the
starting block as visited.
Fixes https://github.com/llvm/llvm-project/issues/120615.
After patch 5ce47a5, some assert crashes occur in Polly. This issue
arises because an instruction from one function queries the Dominator
Tree (DT) of another function. To fix this, the `isHoistableLoad`
function now skips instructions that belong to different function while
iterating.
