Currently, the asm output file for MIPS has no rev info. It can make some trouble, for example: assembler is mips1 by default, gcc is fpxx by default. To assemble the output of gcc -S, we have to pass -mips2 to assembler.gcc/ChangeLog: * gcc/config/mips/mips.c (mips_module_isa_name): New. mips_file_start: add .module mipsREV to all asm output
ping for this patch.
