| Series | [v2] MIPS: add .module mipsREV to all output asm file | expand |
Please ignore this post, as I mistakenly used -1 instead of -2.

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 --- gcc/config/mips/mips.c | 41 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+)
