[PATCH] D69979: clang: Guess at some platform FTZ/DAZ default settings

[Craig Topper via Phabricator via cfe-commits]

craig.topper added a comment.

I checked Redhat 7.4 that's on the server I'm using for work. And I had a coworker check his Ubuntu 18.04 system with this program. And both systems printed 1f80 as the value of MXCSR which shows FTZ and DAZ are both 0. Are you seeing something different?

  #include <x86intrin.h>
  #include <stdio.h>
  
  int main() {
    int csr = _mm_getcsr();
    printf("%x\n", csr);
    return 0;
  }
