[PATCH] D105462: [X86] Add CRC32 feature.

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: clang/lib/Basic/Targets/X86.cpp:159
+  // Enable CRC32 if SSE4.2 is enabled.
+  // NOTE: In conformance with GCC behavior, CRC32 is still available even if
+  // it's explicitly disabled.
----------------
This doesn't seem to be true. It causes gcc to crash. https://godbolt.org/z/39rEbsejh
