digitalmars.D.bugs - [Issue 16092] New: AVX registers YMM0-YMM7 are inaccessible to


          Issue ID: 16092
           Summary: AVX registers YMM0-YMM7 are inaccessible to 32-bit asm
           Product: D
           Version: D2
          Hardware: x86
                OS: Linux
            Status: NEW
          Keywords: iasm, rejects-valid, SIMD
          Severity: normal
          Priority: P1
         Component: dmd

          Reporter: Marco.Leise 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.
