[PATCH] D139582: [GVN] Improve PRE on load instructions

[Lu Weining via Phabricator via llvm-commits]

SixWeining added a comment.

This change failed the https://github.com/llvm/llvm-test-suite/blob/main/SingleSource/Regression/C/gcc-c-torture/execute/pr59747.c (-O2/-O3) on many platforms including x86-64.

I think it is easy to reproduce:

  clang -O2 pr59747.c
  ./a.out
