- Subject: Question about simplify_rtx ()
Hello,
In the discussion:
"Question about merging two instructions"
http://gcc.gnu.org/ml/gcc/2005-08/msg00563.html
You showed me that it might be dangerous to replace rtx on the LHS
of a SET using simplify_replace_rtx ().
simplify_rtx () seems safer, is there a good reason why it doesn't
work with INSNs and SETs?
Will a generalized function called simplify_insn () that uses
simplify_rtx () be accepted?
Thanks,
Leehod.
