It looks like this change will cut back the ARMv7Assembler from max register r15 to max register r13, since ARMv7Assembler::lastRegister() returns r13.

Is that the right thing to do? Your ChangeLog doesn't explain why you did it, or why it's right. 

Regardless of whether it's right, it's bad for a build fix patch on one platform to include a behavior change on another platform. They should be two separate patches.

That's the ARMAssembler not the ARMv7Assembler and it has no effect on it. I just put these functions to the right place form MacroAssemblerARM to ARMAssembler as the other Assemblers work. I don't see how this patch effects on the ARMv7Assembler.

CPU(ARM) in FPRInfo.h is true on ARM_TRADITIONAL and ARM_THUMB2 too.

I see. I thought, incorrectly, that MacroAssemblerARM was used by all ARM platforms.
