[PATCH] D75936: Add a Pass to X86 that builds a Condensed CFG for Load Value Injection (LVI) Gadgets [4/6]

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

This change causes a 0.8% compile-time regression for unoptimized builds <http://llvm-compile-time-tracker.com/compare.php?from=a1b04aaea210a9a9fbe0cd9dd7f874e12fa97585&to=e97a3e5d9d428c4d455fa1b1982728bb71f0c397&stat=instructions>. Based on the pipeline test diffs, I expect this is because the new pass requests a bunch of analyses, which it most likely (LVI load hardening disabled) will not need. Would it be possible to compute the analyses only if LVI load hardening is actually enabled?
