--- Comment #27 from Thomas Koenig <tkoenig at gcc dot gnu.org> --- (In reply to # David Edelsohn from comment #26) > What is AVX-specific, as opposed to SIMD vector size-specific, about this > feature? It seems that this should be enabled for all SIMD architectures of > the appropriate width. You're right, this might as well apply to other architectures where SIMD instructions are available only on some architectures, but cannot be turned on by default because they are not universally implemented. I would need three pieces of information: - What to put into the libgfortran config file to check if the installed binutils support the SIMD extension in question - How to check at runtime for the specific processor version - Which options to pass to __attribute__((__target__ .. Then it is relatively straightforward to put this in.
