Add a MCObjectFormat class so that code common to all targets that use a single object format can be shared. This also adds support for mov zed+(bar-foo), %eax on ELF and COFF targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116675 91177308-0d34-0410-b5e6-96231b3b80d8 2010-10-16 18:23:53 +00:00			`// RUN: llvm-mc -filetype=obj -triple x86_64-pc-linux-gnu %s -o - \| elf-dump \| FileCheck %s`

Fixing r116753 r116756 r116777 The failures in r116753 r116756 were caused by a python issue - Python likes to append 'L' suffix to stringified numbers if the number is larger than a machine int. Unfortunately, this causes a divergence of behavior between 32 and 64 bit python versions. I re-crafted elf-dump/common_dump to take care of these issues by: 1. always printing 0x (makes for easy sed/regex) 2. always print fixed length (exactly 2 + numBits/4 digits long) by mod ((2^numBits) - 1) 3. left-padded with '0' There is a residual common routine that is also used by macho-dump (dataToHex) , so I left the 'section_data' test values alone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116823 91177308-0d34-0410-b5e6-96231b3b80d8 2010-10-19 17:39:10 +00:00			`// CHECK: # Relocation 0x00000000`
