Hello, Reference: BLFS Book, v2015-01-22
In the Firefox source, './configure --help' reads "--enable-optimize=[OPT] Specify compiler optimization flags [OPT=-O]" which, the way I interpret it, implies the build uses O as the default. In Note (... gcc versions ranging from 4.8 to 4.9.1 ...), the command test $(uname -m) = "i686" && sed -i 's/enable-optimize/&=-O2/' mozconfig \ || true seem to force optimization to O2 (again, if I interpret it correctly). O2 is to optimize even more (i.e., higher level) than O (= O1) which appears to contradict the statement: "... [please] reduce the level of optimization with: [the above command]". Am I wrong (again)? Thanks, -- Alex
