Are you sure? I doubt it. It would need a full asm parser to do this properly and then even it could be wrong (e.g. when the sections are switched like Linux does extensively) gcc doesn't have such a parser. Also on x86 gcc doesn't need to care about long/short anyways because the assembler takes care of this and the other instructions who cared about this (loop) isn't generated anymore. You're probably confusing it with some other compiler, who sometimes do this. e.g. the Microsoft inline asm syntax requires assembler parsing in the compiler. > I wonder it it also affects the instruction count the inline heuristics > use? AFAIK it counts like one operand. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
