Subject: RE:  internal compiler error with bogus asm output constraint

Hello,

I apologize if my question sounded like criticism, It is really more of a
reflection on me (my ability to learn) than on GHU. 

I'm trying to get the compiler to accept this asm instruction:

/*		asm("ori		r5, r5, (ARCH_MSR_ME |
ARCH_MSR_RI)");*/

Using extended asm as this:

		__asm__ ("ori	%0,%1,%2"
				: "=r" ("r5")
				: "0" ("r5"), "g" (ARCH_MSR_ME |
ARCH_MSR_RI));

And the compiler is giving me:

Error: assignment of read-only location
Error: incompatible types of assignment

I guess I'm not properly interpreting the documentation on how to use
registers in the asm, is that correct?

Thanks,

Dave

Well, those docs are all we have. If you have any more concrete criticism,
feel free to file a bug about it.
