--- Comment #12 from Jan Hubicka <hubicka at ucw dot cz> --- > It still fails for me with the current trunk: > > $ ../configure --prefix=/tmp/gcc/ --disable-multilib --without-isl > --disable-libsanitizer --with-build-config=bootstrap-lto-lean > $ make profiledbootstrap -j123 I did profiledbootstrap thru lunch and except that I hit some -Werror issues it passed w/o problems. I will try to replicate it with your flags. You may look how much the values differ if it looks like another roundoff or something else. The test should disable itself for profiled functions since for IPA count we subtract the time spent in inline clones from the main function which is prone to roundoff errors so one can't test time to match precisely.
