No it doesn't. There is a plenty of Linux code that doesn't have the stack aligned on 16-byte boundary. (at least anything that was compiled with the old gcc that didn't have -mpreferred-stack-boundary switch). Please don't change i386 ABI. AFAIK only MacOSX/x86 enforced aligned stack. -- mikulas at artax dot karlin dot mff dot cuni dot cz changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |UNCONFIRMED Resolution|DUPLICATE | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40838
