https://issues.dlang.org/show_bug.cgi?id=15242 Issue ID: 15242 Summary: Allow version or static if blocks in asm blocks Product: D Version: D2 Hardware: x86_64 OS: Windows Status: NEW Severity: enhancement Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: aliloko gmail.com That would allow to write x86 asm blocks that work both in 32-bit and 64-bit easily. Porting asm from 32-bit to 64-bit often involved few modifications. - general register changed when storing pointers (EAX => RAX) - movsxd for the occasional sign-extension - changing offsets Currently, one is forced to duplicate instructions and keep them in sync. --
