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. llvm-svn: 116823
