This is just insane, but I thought the compiler automatically expanded normal memcpy to __intel_fast_memcpy. I just checked and my Intel C and C++ compilers (versions 10 and 11) do this automatically at -O2 and above. Should PETSc ever be calling it directly? Should we instead generate three files one for each language? If it's really necessary, why not put both in the same header guarded by #ifdef __cplusplus ? -------------- next part -------------- An HTML attachment was scrubbed...
