Summary: AVX registers YMM0-YMM7 are inaccessible to 32-bit asm
Keywords: iasm, rejects-valid, SIMD
Assignee: nobody at puremagic.com
Reporter: Marco.Leise at gmx.de
Similar to the situation with SSE, the lower half of YMM registers is available
to 32-bit code, but in DMD they are 64-bit only. In fact XMM and YMM share the
registers like EAX and RAX do.
Without this capability and with DMD's lack of SIMD support in 32-bit through
intrinsics, it is impossible to use AVX in DMD in 32-bit mode.
