Hi all: Currently I am studying peephole optimization in gcc. I defined a peephole using "define_peephole", but nothing happened. It seems gcc does do the pattern match work in codes surrounded by "HAVE_peephole", but codes from "out-template" in that "define_peephole" are not compiled into gcc at all.
I know "define_peephole" is deprecated, so not sure about whether define_peephole still works in gcc-4.2.4, or I just missed something important? Thanks, any tips will be appreciated! -- Best Regards.
