Hi Eric, Thanks for the patch. I'm a bit concerned about the interaction this will have with microMIPS which can (albeit not implemented today) use 2-byte alignment on function entry points. Is the solution for other targets to mandate 4-byte alignment when using function descriptors? If so then I don't see a problem with this. We will have to account for that when GCC allows 2-byte aligned microMIPS functions. Thanks, Matthew
