================
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
