--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- As for inline asm, one has always the possibility to support both through the {att|intel} syntax, not really sure in which dialect toplevel asms would be emitted though, and whether we allow inlining between functions in different asm dialects (if yes, then of course all the inline asms in the mixed environment would need to be written to support both dialects).
