            Bug ID: 80336
           Summary: AVX512: operand type mismatch for `vxorps'
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mail@sven-woop.de
  Target Milestone: ---

The following code fails to compile with the GCC 6.3 and trunk:

#include <immintrin.h>

inline __attribute__((always_inline))    float fmin(float    a, float    b) {
return a<b ? a:b; }
inline __attribute__((always_inline))    float fmax(float    a, float    b) {
return a<b ? b:a; }
float intersect(float time) {
  return fmax(fmin(time*10, 0.0f), 9.0f);
}

Command Line to reproduce:
g++ -mavx512f -mavx512dq test.cpp -c -o test

Output:
/tmp/cc0D8mRE.s: Assembler messages:
/tmp/cc0D8mRE.s:18: Error: operand type mismatch for `vxorps'

The following works for some reason:
g++ -mavx512f test.cpp -c -o test
