Just care ia64.md. itanium1.md is for the description of itanium1 processor's pipeline, and itanium2.md for the description of itanium2 processor's pipeline. The are both used in the instruction scheduling pass.

Thanks for the hints, I have already noticed that insn list is match against the RTL templates to emit assembly code. However, I found 3 md files, ia64.md, itanium.md, itanium2.md, each file is very big... would you mind giving some hints on the differences between them? Especially, I am working on itanium2 architecture. (I have found many insn templates in ia64.md, but how about itanium.md and itanium2.md?) 在 07-2-4，Paul Yuan<[EMAIL PROTECTED]> 写道： > 1) Modify the final() in final.c to emit some code before ld and st > before outputting the assembly. > 2) Modify the MD file.
