Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |INVALID Status|UNCONFIRMED |RESOLVED --- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- I tested: ``` #include <x86intrin.h> extern __m128 a,b,c; void foo(){ a = _mm_nmsub_ps(a,b,c); } ``` GCC produces correctly: foo: vmovaps a(%rip), %xmm1 vmovaps b(%rip), %xmm2 vfnmsubps c(%rip), %xmm2, %xmm1, %xmm0 vmovaps %xmm0, a(%rip) ret > However the fma4intrin.h mapping has changed from 4.5 -> 4.6, > which might likely have introduced the error. No r0-103863-g89509419968e2b (which was included in GCC 4.6.0) fixed the defintion.
