Re: how to add new instruction
i'm afraid so. i add a new rtl expression in rtl.def. and when i add a
section in i386.md, it said the instruction is undefined.
You need to be much more explicit about what happened here if you want
help. You need to give the exact error you got, the exact command that
was used to produce it, the exact change you made to the i386.md file, etc.
