Hi, Is there an easy way to figure out which options need to be passed to later compilation passes? If I do a: gcc -S -dA -fverbose-asm -mcpu=750 -O2 -mmultiple -fpic gcc1test.c What should be used for assembly: gcc -c ??? gcc1test.s and linking: gcc -ogcc1test gcc1test.s I am pretty sure the link will need the -fpic. Probably also something like -pthread? Maybe the assembler would need to allow something like altivec? So as a general rule should it see the cpu (or arch) option? Does anyone else need the -O2? kevin P.S.: Do the order of the optimization options matter: '-O2 -mcpu=750 -mmultiple' the same as '-mmultiple -mcpu=750 -O2'?
