| void | setAssembler (MCAssembler *A) |

| bool | allowAutoPadding () const |
| Return true if this target might automatically pad instructions and thus need to emit padding enable/disable directives around sensative code. | |
| bool | allowEnhancedRelaxation () const |
| Return true if this target allows an unrelaxable instruction to be emitted into RelaxableFragment and then we can increase its size in a tricky way for optimization. | |
| virtual void | reset () |

| std::unique_ptr< MCObjectWriter > | createObjectWriter (raw_pwrite_stream &OS) const |
| Create a new MCObjectWriter instance for use by the assembler backend to emit the final object file. | |
| std::unique_ptr< MCObjectWriter > | createDwoObjectWriter (raw_pwrite_stream &OS, raw_pwrite_stream &DwoOS) const |
| Create an MCObjectWriter that writes two object files: a .o file which is linked into the final program and a .dwo file which is used by debuggers. | |
