Fix cmpli usage in power6 memset.
Building glibc for powerpc64 with recent (2.27.51.20161012) binutils, with multi-arch enabled, I get the error: ../sysdeps/powerpc/powerpc64/power6/memset.S: Assembler messages: ../sysdeps/powerpc/powerpc64/power6/memset.S:254: Error: operand out of range (5 is not between 0 and 1) ../sysdeps/powerpc/powerpc64/power6/memset.S:254: Error: operand out of range (128 is not between 0 and 31) ../sysdeps/powerpc/powerpc64/power6/memset.S:254: Error: missing operand Indeed, cmpli is documented as a four-operand instruction, and looking at nearby code it seems likely cmpldi was intended. This patch fixes this powerpc64 code accordingly, and makes a corresponding change to the powerpc32 code. Tested for powerpc, powerpc64 and powerpc64le by Tulio Magno Quites Machado Filho * sysdeps/powerpc/powerpc32/power6/memset.S (memset): Use cmplwi instead of cmpli. * sysdeps/powerpc/powerpc64/power6/memset.S (memset): Use cmpldi instead of cmpli.
