disassembler API. Hooked this up to the ARM target so such tools as Darwin's otool(1) can now print things like branch targets for example this: blx _puts instead of this: blx #-36 And even print the expression encoded in the Mach-O relocation entried for things like this: movt r0, :upper16:((_foo-_bar)+1234) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129284 91177308-0d34-0410-b5e6-96231b3b80d8
