[TableGen] Do not order register classes based on heap addresses (#185644)
Compare registers using their enum values instead, which I suspect was
the intention in the first place, since we already have lexicographical
ordering defined for CodeGenRegisters.
This does not cause any changes in .inc files and is likely NFC, but
it's still best to have it be deterministic.
[libc] 185136 - added iswlower entry point (#185221)
Changes include:
- Added iswlower entrypoint in wctype.yaml to expose the function
- Created iswlower.h header and iswlower.cpp implementation
- Added CMake entrypoint object for iswlower
- Created unit test in iswlower_test.cpp
- Added test entry to wctype CMakeLists.txt
this PR helps in exposing iswlower which internally calls islower on
wide character
built using : ninja -C build libc
tested using : ninja libc_wctype_unittests and all the 3 tests passed
resolves issue #185136
[lldb][PlatformDarwin][NFC] Use formatv-style format string in Locate ExecutableScriptingResourcesFromDSYM warning message (#185640)
About to make changes in this area and using `formatv` instead of
`printf` style format specifiers makes those easier to follow.
[Hexagon] Fix 64-bit funnel shift miscompilation with register shift amounts (#183669)
64-bit regpair shift amounts are treated as signed 7-bits, so a
complement
shift amount of 64 (when the primary amount is 0) is sign-extended to
-64,
reversing the shift direction and producing incorrect results. This
affected
any 64-bit rotate or funnel shift where the runtime shift amount could
be 0
(making the complement 64) or >= 64.
Fix by masking the shift amount to [0, 63] and computing the complement
as
(m - 64), which is always in [-64, -1]. Using lsl/lsr (logical shift)
instructions with this negative amount causes the hardware to reverse
the
shift direction while zero-filling vacated positions:

shfmt: updated to 3.13.0
3.13.0
This release introduces support for Zsh in the parser and formatter, which was
tracked in issue 120 alongside the label zsh . While support is not complete,
it should be far enough for many use cases.
ugrep: updated to 7.6.0
7.6.0
new options --max-size and min-size to search files whose physical size is in the specified MIN and/or MAX range
fix zsh completion syntax error
update option --ignore-file to ignore files and directories specified in an .gitignore file as an absolute /glob to ignore those matching the glob under its sub-directories
fix emulation of GNU grep option -z (--null-data) to match newlines (zero bytes internally) with pattern \s (space), which requires non-standard regex behavior internally to include matching zero bytes with pattern \s
update --ignore-file=FILE to accept a FILE pathname to a non-local gitignore FILE that applies globally to ignore files and directories, similar to --exclude-from=FILE, but with the minor difference that gitignore rules match both files and directories with a single glob
fix third-party sourced zopen.c library (BSD open source) one-byte read beyond its allocated struct s_zstate state variable in getcode()
fix -m (--max-count) with context options -A or -C sometimes producing garbled after-context output that may cause a crash in the worst case
fix reverse sort by date --sort=rchanged and --sort=rcreated not recognized by the TUI at startup
update ugrep to search named pipe files specified as arguments on the command line instead of skipping them by default, such as process substitutions; also improve Linux special system files /proc and /sys skipping and/or reading and option -z file read error handling to avoid possible pipe fd leaks when thousands of /proc files are searched that produce (expected) read errors
support option --no-empty while using full grep-emulation mode, i.e. when ugrep is renamed to grep
[OpenMP] Add definitions of FLATTEN and SPLIT to OMP.td (#185642)
Add the definitions of the "flatten" and the "split" constructs to the
OMP.td file. This will allow the implementation efforts in clang and
flang to proceed independently.
There is no other functionality added in this patch.
The "flatten" construct is defined in the OpenMP Technical Report 14:
https://www.openmp.org/wp-content/uploads/openmp-TR14.pdf
interfaces: useless refactor for the benefit of the solution
This code is silly. PPP on CARP is silly, too. We start PPP
before we even have a CARP address.
The answer to this is simple: defer start and stop to the
CARP hook, done?!
The bigger question is what happens when no CARP is configured
so that we don't end up never starting PPP.
[CIR] Ensure strings are null-terminated, better deal with trailing null (#185513)
Our current implementation of string lowering did some work to remove
extra trailing zeros, plus do a 'zero' constant. That is unchanged by
this patch. However, this patch ALSO ensures that we do the 'remove
extra trailing zeros' to remove ALL trailing zeros, which likely has
canonicalization benefits later on.
However, the real benefit of this patch is to make string emission by
default emit a null-terminator, which fixes the virtual table 'name'
field get lowered correctly. We do this by making the builder::getString
function take an argument (true by default) that will ensure we add a
null terminator if necessary.
This reflects the llvm::ConstantDataArray::getString function, which has
the same functionality. However, doing this during lowering seems
incorrect, since the FE is the one that knows whether these null
terminators are necessary. There is not currently an 'opt out' use of
the behavior, but the functionality is left in place to better reflect

[CIR][AArch64] Add lowering for remaining `vabd_*` builtins (#185478)
Implement the missing CIR lowerings for the AdvSIMD (Neon) `vabd_*`
(absolute difference) intrinsic group.
Most `vabd` variants were already supported (see
https://github.com/llvm/llvm-project/pull/183595); this patch
completes the remaining cases listed in [1].
Move the corresponding tests from:
* clang/test/CodeGen/AArch64/neon_intrinsics.c
to:
* clang/test/CodeGen/AArch64/neon/intrinsics.c
The implementation mirrors the existing lowering in
CodeGen/TargetBuiltins/ARM.cpp. To support this, add the
`emitCommonNeonSISDBuiltinExpr` helper.

[mlir] Fix tests not to depend `llvm-strings` in standalone build (#185187)
Move the `llvm-strings` test dependency into the non-standalone test
dependency block, to fix standalone builds after #182846. While at it,
reformat the block to make it more visible.
