[PowerPC] Implement writeNopData This implements a proper PPCAsmBackend::writeNopData routine that actually writes PowerPC nop instructions. This fixes the last remaining difference in object file output (text section) between the integrated assembler and GNU as that I've seen anywhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185662 91177308-0d34-0410-b5e6-96231b3b80d8 2013-07-04 18:28:46 +00:00			`# RUN: llvm-mc -filetype=obj -triple=powerpc-unknown-linux-gnu %s \| llvm-readobj -s -sd - \| FileCheck %s`

PPC: Allow partial fills in writeNopData() When asked to pad an irregular number of bytes, we should fill with zeros. This is consistent with the behavior specified in the AIX Assembler Language Reference as well as other LLVM and binutils assemblers. N.B. There is a small deviation from binutils' PPC assembler: when handling pads which are greater than 4 bytes but not mod 4, binutils will not emit any NOP sequences at all and only use zeros. This may or may not be a bug but there is no excellent rationale as to why that behavior is important to emulate. If that behavior is needed, we can change writeNopData() to behave in the same way. This fixes PR17352. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191426 91177308-0d34-0410-b5e6-96231b3b80d8 2013-09-26 09:18:48 +00:00			`.byte 0x42`
