Core	[BOLT][print] Add option '--print-only-file' (NFC) (#168023) With this option we can pass to BOLT names of functions to be printed through a file instead of specifying them all on command line.	8 个月前
Passes	[BOLT] Extend Inliner to work on functions with Pointer Authentication (#162458) The inliner uses DirectSP to check if a function has instructions that modify the SP. Exceptions are stack Push and Pop instructions. We can also allow pointer signing and authenticating instructions. The inliner removes the Return instructions from the inlined functions. If it is a fused pointer-authentication-and-return (e.g. RETAA), we have to generate a new authentication instruction.	8 个月前
Profile	[BOLT] Move call probe information to CallSiteInfo Pseudo probe matching (#100446) needs callee information for call probes. Embed call probe information (probe id, inline tree node, indirect flag) into CallSiteInfo. As a consequence: - Remove call probes from PseudoProbeInfo to avoid duplication, making it only contain block probes. - Probe grouping across inline tree nodes becomes more potent + allows to unambiguously elide block id 1 (common case). Block mask (blx) encoding becomes a low-ROI optimization and will be replaced by a more compact encoding leveraging simplified PseudoProbeInfo in #166680. The size increase is ~3% for an XL profile (461->475MB). Compact block probe encoding shrinks it by ~6%.

CMakeLists.txt	[BOLT] Enable standalone build (#97130) Continue from #87196 as author did not have much time, I have taken over working on this PR. We would like to have this so it'll be easier to package for Nix. Can be tested by copying cmake, bolt, third-party, and llvm directories out into their own directory with this PR applied and then build bolt. --------- Co-authored-by: pca006132 <john.lck40@gmail.com>	2 年前
