I wonder if there is a target or a use case that requires or prefers realigning the stack to an alignment that is smaller than the default stack alignment. If there is no such target or use case, I think we can just using the existing attribute StackAlignment (with value 0) rather than adding a new function attribute "stackrealign", which will ensure the stack is at least aligned to the default value and force realigning the stack. http://reviews.llvm.org/D11815 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
