The Z constraint specifies an r+r memory address, and the y modifier expands to the "r, r" in the asm string. For this initial implementation, the base register is forced to r0 (which has the special meaning of 0 for r+r addressing on PowerPC) and the full address is taken in the second register. In the future, this should be improved. llvm-svn: 167388
