gcc multiple optimization levels ?
Does anyone know which optimization level gcc would default to if more than one was specified at the command line?
For example if the Makefile had -O set and your CFLAGS environment variable added -O3 to the end of the command, would gcc optimize at -O or -O3 ?
(edit: spelling errors)
