      1 This README describes a sample invocation of disasm.py whose purpose is to test
      2 the low level ARM/Thumb disassembly functionality from llvm using the llvm-mc
      3 command line.  We invoke gdb on an executable, try to disassemble a function,
      4 and then read the memory contents of the disassembled function.
      5 
      6 The byte contents are written into a file named disasm-input.txt and then we
      7 invoke llvm-mc -disassemble plus options (set with the -o/--options) on the
      8 byte contents.
      9 
     10 See the following for a sample session using this command:
