This replaces frame size -4/-8 with the NOFRAME flag in mips and mips64 assembly. This was automated with: sed -i -e 's/\(^TEXT.*[A-Z]\),\( *\)\$-[84]/\1|NOFRAME,\2$0/' $(find -name '*_mips*.s') Plus a manual fix to mkduff.go. The go binary is identical on both architectures before and after this change.
