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: m...@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
