[LLVMdev] Looking for ideas on how to make llvm-objdump handle both arm and thumb disassembly from the same object file
...CPU() twice, once with an arm TripleName and once with a matching thumb TripleName. Then for each 32-bit ARM cpu it will default to one or the other disassembler. Then as it disassembles and finds a symbol in the symbol table for the current PC being disassembled it will see of the symbol has the N_ARM_THUMB_DEF bit set or not. And then switch disassemblers between the arm and thumb disassemblers. While this is a bit of a hack there are a limited set of Mach-O cpus otool(1) deals with.
For llvm-objdump, it eventually just calls TheTarget->createMCDisassembler() and gets one disassembler for TheTarget...
