This last one is particularly important on Win64, where xmm6-15 are callee-save, and not restoring their contents leads to undefined results. In external asm (e.g. yasm), you do this by using: -cglobal functon_name, num_args, num_regs, num_xmm_regs +cglobal function_name, num_args, num_regs, num_xmm_regs In inline asm, you specify clobbered registers at the end of your asm: __asm__(".." ::: "%eax").
