…w clangOptions library" (llvm#167374) This relands llvm#167348. The original PR was reverted due to a reported build failure, which was later diagnosed as a local issue in the developer’s checkout or build state. See discussion here: llvm#163659 (comment) No additional changes have been made in this reland.
This isn't reachable today but will come into play once we reorder passes for llvm#147352 and llvm#147351. Note that the `CBufferRowIntrin` helper struct is copied from the `DXILCBufferAccess` pass, but it will be removed from there when we simplify that pass in llvm#147351
trans bf16 insts do not support clamp and omod
…m#167276) Preparing to moving most of implementation out of the header file. * llvm#167280 --------- Co-authored-by: Naveen Seth Hanig <naveen.hanig@outlook.com> Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>
…lvm#167383) Re-land: Add test for Complex imag literal GNU extension after updating the name
…#152830) This adds the codegen support for the dyn_groupprivate clause.
It is undefined behavior to call a function with a mismatched calling convention. Rather than crash on this behavior, it should compile. This LLVM defect was identified via the AMD Fuzzing project.
…166658) (llvm#166846) The previous implementation in llvm#166252 (rolled back in llvm#166658) caused buildbot failures due to a bug in an added test. The modified `UseAfterClose` did not pass a `struct flock` value to `fcntl`: https://github.com/llvm/llvm-project/blob/2d5170594147b42a37698760d6e0194eec4f1390/libc/test/src/fcntl/fcntl_test.cpp#L175 Which ASAN caught and errored in the `fcntl` implementation when the unspecified argument was accessed: https://github.com/llvm/llvm-project/blob/c12cb2892c808af459eaa270b8738a2b375ecc9b/libc/src/__support/OSUtil/linux/fcntl.cpp#L59
Fixes regressions with llvm#159493 after 476a6ea
Use getDefiningRecipe to future-proof the code. Split off from llvm#156262 as suggested.
This commit introduces `SpecialCaseList::Match`, a small struct to hold the matched rule and its line number. This simplifies the `match` methods by allowing them to return a single value instead of using a callback. --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>
Make the systemSupportsMemoryTagging() function return even on system that don't support memory tagging. This avoids the need to always check if memory tagging is supported before calling th function. Make systemSupportsMemoryTagging() cache the getauxval return value instead of calling the function every time. Updated the code that calls systemSupportsMemoryTagging().
This hardens the code to check based on WideMember0's operands. This ensures each call will go through the same check. Should be NFC currently but needed when generalizing in follow-up patches.
…m#153608) This should be the peephole's job. Because and sets V flag to 0, this is why signed comparisons with 0 are okay to replace with tst. Note this is only for AArch64, because ANDS on ARM leaves the V flag the same. Fixes: llvm#154387
… of pattern matching (llvm#166806) Flang alias analysis used to find allocation site by pattern matching allocation ops in mainly FIR dialect. This MR extends the characterization to instead characterize based on whether the result of an op has MemAlloc effect.
After llvm#164165, we emit warnings from non-system headers by default. This change only preserves functionality of `clang-tidy` as it was before the change.
…m#158224) Both conceptually belong to the same subtarget, so it should not be necessary to pass in the context TargetRegisterInfo to any TargetInstrInfo member. Add this reference so those superfluous arguments can be removed. Most targets placed their TargetRegisterInfo as a member in TargetInstrInfo. A few had this owned by the TargetSubtargetInfo, so unify all targets to look the same.
Will help in future patches.
The save stats test would fail downstream due to the tests being run from a read only directory. The cwd flag would attempt to place the statistics in that read only directory, causing an error. This patch ensures that the tests are always run from a temp directory.
llvm#167350) fwrite and friends don't modify errno if no error occurred. Therefore frite_unlocked's return value shouldn't be constructed from errno without checking if an error actually occurred. This fixes an error introduced by llvm@9e2f73f
