Previously we would always print the offset as decimal, regardless of the formatting requested. Now we use the formatImm() helper so the value is printed as the client (LLDB in the motivating example) requested. Before: ldr.w r8, [sp, #180] @ always After: ldr.w r8, [sp, #0xb4] @ when printing hex immediates ldr.w r8, [sp, #0180] @ when printing decimal immediates rdar://17237103 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210701 91177308-0d34-0410-b5e6-96231b3b80d8
