You'd get similar error messages if you tried __asm__ ("mfspr foo, fum;"); In other words, gas is interpreting the register names as arbitrary symbols. But when i try to compile it, It throws error mentioned after the code snippet.
Will this let me use a more restricted (i.e. cc1: error: invalid option 'regnames' /usr/libexec/gcc/darwin/ppc/as: I don't understand 'm' flag! /usr/libexec/gcc/darwin/ppc/as: I don't understand 'r' flag! /usr/libexec/gcc/darwin/ppc/as: I don't understand 'e' flag! /usr/libexec/gcc/darwin/ppc/as: I don't understand 'a' flag! /usr/libexec/gcc/darwin/ppc/as: Flag This is the accepted answer.

Comment 40 Feng Qian (Google) 2006-01-30 13:41:50 PST Two comments on the assembly code: 1. 64-bit instruction is ldarx/stdcx/cmpd 2. Sorry, I'll help now. Why must the speed of light be the universal speed limit for all the fundamental forces of nature? Some processors do unexpected and inconsistent things when the lwarx that created a reservation and a stwcx.
There is a powerpc64 case below in this case statement for 64-bit binary code. It only shows up as a few lines of code in a few configuration scripts. r4,r0,r5 0xffff8090 <___compare_and_swap32+16>: bne- 0xffff8080 <___compare_and_swap32> 0xffff8094 <___compare_and_swap32+20>: li r3,1 0xffff8098 <___compare_and_swap32+24>: blr 0xffff809c <___compare_and_swap32+28>: li r3,0 0xffff80a0 <___compare_and_swap32+32>: blr Comment 31 Brendan Eich [:brendan] 2005-10-28 20:59:44 PDT How can I We could go back to your #ifdefs that leave OS X/PPC out, but I'd like to get this on OS X/PPC too.

Why does argv include the program name? I am pretty sure that I should be only using the -m440 switch and not the -mbooke switch though.

This is just a guess, but it may be that the assembler doesn't like having the letter r in front of register numbers.
I dislike the idea of using env variables when a pre-existing configure option will do. This assembler was configured for a target of `powerpc-linux'.

References to %0 should be %3 when "w" is being used, it makes the intent clearer. + : "cc", "memory","r6"); This doesn't clobber memory.

I tried to add the 386 support in as unobtrusive a fashion as possible.
