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?
