https://issues.dlang.org/show_bug.cgi?id=16092 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 Assignee: nobody@puremagic.com 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. -- |
