Hi there. I'm trying to build software for the AMD AU1100 processor using version 3.3.2 of the gnu compiler, and I'm having trouble figuring out the -march, -mtune, etc settings. Version 2.95 of gcc uses something like -mcpu=r4600, but this doesn't work with 3.3.2. I've tried other likely-looking options (e.g. -mips32), but the compiler fails to assembler instructions like mtc0 and cache. Has anyone built for the AU1100 using gcc 3.3.2? If so, could you tell me the cpu options you used please? Thanks Ian Hamilton.
