When you're still using gcc's inline asm, would you be able to declare those 36 registers as clobbered? I thought you mentioned a list of 30 regs specified in the asm statement - does this apply to clobbered regs as well? If you can't specify all 36, then with inline asm you'd be stuck between suboptimal code (preloading fewer than all 36 elements) and unreliable code (which may break with any recompile in a slightly different environment). So this would be yet another reason for you to move to using a separate assembly source file. Alexander
