--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Nate Eldredge from comment #8) > So that makes this into a compatibility issue. I disagree there. Inline-asm does not need to be compatiable between two compilers at all. In fact it is just happens that clang adopted GNU style inline-asm rather than inventing their own style (badly by the way for most targets because inline-asm depends on GCC's own internal definitions to get correct).
