29441e4f5fa5f5c7709f7cf180815ba97f611297 - [IR] Convert from nocapture to captures(none) (#123181)

Wed, 29 Jan 2025 15:56:47 +0000

[IR] Convert from nocapture to captures(none) (#123181)This PR removes the old `nocapture` attribute, replacing it with the new `captures` attribute introduced in #116990. This change is intended to be essentially NFC, replacing existing uses of `nocapture` with `captures(none)` without adding any new analysis capabilities. Making use of non-`none` values is left for a followup. Some notes: * `nocapture` will be upgraded to `captures(none)` by the bitcode reader. * `nocapture` will also be upgraded by the textual IR reader. This is to make it easier to use old IR files and somewhat reduce the test churn in this PR. * Helper APIs like `doesNotCapture()` will check for `captures(none)`. * MLIR import will convert `captures(none)` into an `llvm.nocapture` attribute. The representation in the LLVM IR dialect should be updated separately. List of files: /llvm-project/llvm/test/Transforms/PhaseOrdering/AArch64/indvars-vectorization.ll

d1e5e6735a845f1281f11389da1e5a55a0d2e87a - [PhaseOrdering] Update test RUN lines to use `-passes="default"` to allow evaluation by DOS batch scripts. NFC.

[PhaseOrdering] Update test RUN lines to use `-passes="default"` to allow evaluation by DOS batch scripts. NFC.`-passes='default'` 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"` instead.

[InstCombine] Infer nusw + nneg -> nuw for getelementptr (#111144)If the gep is nusw (usually via inbounds) and the offset is non-negative, we can infer nuw. Proof: https://alive2.llvm.org/ce/z/ihztLy List of files: /llvm-project/llvm/test/Transforms/PhaseOrdering/AArch64/indvars-vectorization.ll

dce77a357948709e335910ddc07f9c3f2eb2ac4b - [IndVars] Preserve flags of narrow IV inc if replacing with wider inc. (#80446)

Sat, 10 Feb 2024 18:11:17 +0000

[IndVars] Preserve flags of narrow IV inc if replacing with wider inc. (#80446)We are replacing a narrow IV increment with a wider one. If the original (narrow) increment did not wrap, the wider one should not wrap either. Set the flags to be the union of both wide increment and original increment; this ensures we preserve flags SCEV could infer for the wider increment.
