This is one of the things in inline asm that is tightly tied to GCC internals. You should emulate GCC's behaviour faithfully if you want to claim you implement the inline asm GNU C extension. > --- a/include/ChangeLog > +++ b/include/ChangeLog That should not be part of the patch? Changelog entries should be verbatim in the message you send. The size of this patch already makes clear this is a bad idea, imo. This code is already hard enough to read. Segher
