ARM .align NOP padding uses different encoding pre-ARMv6. Patch by Kristof Beyls and James Malloy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137723 91177308-0d34-0410-b5e6-96231b3b80d8 2011-08-16 17:06:20 +00:00			`@ RUN: llvm-mc -triple armv4-apple-darwin %s -filetype=obj -o %t.obj`

Correct ARM NOP encoding The encoding of NOP in ARMAsmBackend.cpp is missing a trailing zero, which causes the emission of a coprocessor instruction rather than "mov r0, r0" as indicated in the comment. The test also checks for the wrong encoding. http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20121203/157919.html git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169420 91177308-0d34-0410-b5e6-96231b3b80d8 2012-12-05 21:01:27 +00:00			`@ CHECK: ('_section_data', '020081e0 0000a0e1 0000a0e1 0000a0e1 020081e0')`
