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

Tue, 31 Dec 2024 15:25:12 +0000

[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/loopflatten.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.

f269ec230e2b65df165009b85f1e8cae2aeb1bba - [LoopFlatten] Move it from LPM2 to LPM1

Wed, 19 Jan 2022 14:09:59 +0000

[LoopFlatten] Move it from LPM2 to LPM1In D110057 we moved LoopFlatten to a LoopPassManager. This caused a performanceregression for our 64-bit targets (the 32-bit were unaffected), the pass is nolonger triggering for a motivating example. The reason is that the IR is justvery different than expected; we try to match loop statements and particularuses of induction variables. The easiest is to just move LoopFlatten to a placein the pipeline where the IR is as expected, which is just beforeIndVarSimplify. This means we move it from LPM2 to LPM1, so that it actuallyruns just a bit earlier from where it was running before. IndVarSimplify isresponsible for significant rewrites that are difficult to "look through" inLoopFlatten.Differential Revision: https://reviews.llvm.org/D116612 List of files: /llvm-project/llvm/test/Transforms/PhaseOrdering/AArch64/loopflatten.ll
