This is for the lldb team so most of but not all of the values are to be printed as hex with this option. Some small values like the scale in an X86 address were requested to printed in decimal without the leading 0x. There may be some tweaks need to places that may still be in decimal that they want in hex. Specially for arm. I made my best guess. Any tweaks from here should be simple. I also did the best I know now with help from the C++ gurus creating the cleanest formatImm() utility function and containing the changes. But if someone has a better idea to make something cleaner I'm all ears and game for changing the implementation. rdar://8109283 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169393 91177308-0d34-0410-b5e6-96231b3b80d8
