I talked to Andrew about what files he changed in GCC and created and | |||
tested this new patch. Andrew also mentioned changing some assembly | |||
files in glibc but I don't see any use of '.section .note.GNU-stack' in | |||
any assembly files in glibc (for any platform) so I wasn't planning on | |||
creating a glibc to add them to mips glibc assembly language files. | |||
OK to check in this patch? | |||
