--- Comment #14 from jbeulich at suse dot com --- (In reply to LIU Hao from comment #13) > MSVC outputs: > ``` > get_value PROC ; COMDAT > mov ecx, DWORD PTR eax > mov rax, QWORD PTR rip > mov eax, DWORD PTR [rax+rcx*4] > ret 0 > get_value ENDP > ``` Which as least MASM up to 12.x won't assemble. For one it complains about "rip" being undeclared. And then the load of "ecx" is _not_ a memory access (i.e. the "DWORD PTR" is ignored there). Which is in line with it also objecting to something like "extrn eax:dword". I say this because I'd be happy to help this on the gas side, but only without breaking MASM compatibility. My present plan for gas is (as already outlined in #11) to make quoted identifiers unambiguously mean symbols, not registers. But of course that would still require a gcc side change as well. Unfortunately there continue to be inconsistencies in gas with quoted identifiers in general, and it's not entirely clear yet whether those may need addressing first.
