Test file for compilation
My machine supports AVX, not FMA.
Compile test.c with:
clang -mavx
It says: clang -mavx test.c
test.c:6:25: error: redefinition of '_mm256_fmadd_pd'
static inline __m256d _mm256_fmadd_pd(__m256d a, __m256d b, __m256d c) {
^
/usr/bin/../lib64/clang/4.0.0/include/fmaintrin.h:161:1: note: previous
definition is here
_mm256_fmadd_pd(__m256d __A, __m256d __B, __m256d __C)
Headers for FMA are included. So clearly a redefinition happens. But this
behaviour is not normal.
If I compile with
gcc -mavx, it compiles and run the normal way.</pre>
