--- Comment #7 from David Binderman <dcb314 at hotmail dot com> --- (In reply to Richard Biener from comment #5) > I'll see to test the patch with -O3 bootstrap then - thanks for the info. You are very welcome. With the benefit of hindsight, changes in the -O3 area of the compiler would be well tested before commit with one of 1. bootstrap-O3 2. After a configure command, doing something like this: sed 's/-O2/-O3/' < Makefile > Makefile.tmp diff Makefile Makefile.tmp mv Makefile.tmp Makefile I am not sure of the difference, but they are pretty similar.
