- Organization: MandrakeSoft
Has anyone done any work towards inserting a -fprofile-arcs step into
"make bootstrap"? A search of gcc and gcc-patches list archives didn't
reveal anything immediately...
I'm assuming an implementation would look something like:
build stage1 using platform compiler
build stage2 using stage1 and -fprofile-arcs
build stage3 using stage2 and -fbranch-probabilities
build stage4 using stage3 and -fbranch-probabilities
compare stage 3 and 4 .o files
Maybe this could be called "make profilestrap"? ;-)
