[clang] clang-format two constructors (#226737)
I'd like to change these two in a patch, and the diff looks a bit
confusing since they aren't formatted yet. So format them in a prep
commit to make the diff clearer.
No behavior change.
[libc++][format] Don't leave the output buffer full after a bulk write (#226791)
__output_buffer::push_back writes a code unit before it makes room, so
the buffer must always have a free one. __copy, __transform and __fill
write in chunks of the available space and could end with the buffer
full. Formatting into a back_insert_iterator of a string, vector or
deque goes through a 256 code unit buffer, so an argument or fill whose
length is a multiple of 256, followed by a literal, wrote that literal
past the end of the buffer.
Make room in a full buffer at the end of these functions, as push_back
does.
Fixes #154670
[orc-rt] Rename os-version substitution. (#226863)
This substitution is available and being tested on all platforms. It's
currently only populated on Darwin, but may be useful on other
platforms, so rename it to reflect its role.
[MC] Add ELF::getSymbolInfo and fix bitwise OR between enumeration types. NFC (#226860)
`ELF::STT_FILE | ELF::STB_LOCAL` puts the binding in the type bits,
which only works because STB_LOCAL is 0.
It combines enumerators from two distinct unnamed enums, which is
deprecated in C++20 and ill-formed in C++26 (P2864R2).
[orc-rt] Prefix test tool output, update test. (#226862)
Prefix the triple, page-size, and cpu-features lines of the
orc-rt-process-info-check. The prefixes can be used to ensure that the
test doesn't try to match patterns against the wrong lines.
Also relaxes the feature string check to allow an empty feature string.
[AMDGPU][InstCombine] Fold zero dot operands to accumulator (#225003)
Fold AMDGPU dot intrinsics when either operand is zero.
`dot(a, 0) = 0` and `dot(0, b) = 0`, so replace the intrinsic with its
accumulator.
This avoids unrelated clamp and add/sub reassociation cases.
[SlotIndexes] Add queries for stale indexes
An erased instruction leaves its index list entry in place, making the
index indistinguishable from a block boundary entry. Add
isBlockBoundaryIndex() and isStaleIndex() to tell the two apart, and
canonicalizeIndex() to resolve a stale index to the closest preceding
instruction's register slot, or the block start if none survives.
NFC. No caller yet. LiveDebugVariables is next.
[LiveDebugVariables] Repair stale SlotIndexes
The analysis keeps its indexes from before the first register allocator
until DBG_VALUEs are emitted, by which point passes in between have
erased some of the instructions they point at. Resolve them at the
start of each allocator run and before emitting.
SlotIndexes can then reclaim the entries of erased instructions without
sparing the ones held here, which would have made generated code depend
on -g. Emitted locations are unchanged, except that intervals resolving
to one position now emit a single DBG_VALUE rather than identical
consecutive ones.
[Github] Add LLVM-libc's full-build to Bazel Checks workflow
This PR adds a job to run `bazelisk test --@llvm-project//libc:build_mode=full @llvm-project//libc/...`. It is part of an effort to support LLVM-libc's full build functionality in Bazel.
[bazel][libc] Refactor to allow copts under full-build mode
This PR moves away from having sets of predefined groups of copts and allows just directly using them. This lets the Bazel rules more directly parallel CMake.
