--- Comment #8 from Segher Boessenkool <segher at gcc dot gnu.org> --- Hi Rin, > However, I have a question on this fix. How about the case where > "-Wa,-mXXX" option is given without "-mcpu=YYY" option specified? That might or might not work; the user had better know what he is doing if he uses an assembler option. > This may sound pedantic to you. However, this is dangerous because > some special mnemonics in inline assembler codes can be misassembled. > In addition, for example, "-mcpu=e500" is forbidden whereas "-Wa,-me500" > is possible; the user cannot use instructions for e500 in inline > assembler codes. GCC does not support -me500, right. You need to configure your compiler for a powerpc-*-eabispe* target as far as I know (I'm no expert on this).
