There are various bits of code in and around Druntime and Phobos that hide
inline asm from GDC (or when version = GNU). In my opinion, I think these
should be removed as they only hide GDC bugs that *should* instead be fixed in
the compiler.

Regards

Created an attachment (id=842)
Remove version(GNU){} else { version=ASMx86 } code

Patch to remove it from the notable places in core.cpuid and std.math.

:3

Incase you are curious, GDC still can't generate the correct codegen for the
naked asm inside exp2 and expm1. But then again, the GCC builtin functions make
a better replacement of them for the time being.
