I can't inherit from it (DwarfWriter creates it directly) and there are no call backs to target-specific code (nor registration of such mechanism). Why do you need

...Actions are in conformance with GCC's intrinsics. Also, looks like gcc doesn't produce the CIE nor any of the FDEs, so maybe I have to suppress that as well. > > For all those changes, the only place I can implement, AFAIK, is DwarfException. Now, as a local hack, I have added a new ExceptionABI { None, ARM }; enum to MCAsmInfo to if/else inside DwarfException, but that's far from ideal. > > I'd like to be able to have with DwarfException the same we have with AsmPrinter, calling target-implemented functions (like EmitFunctionBodyStart, etc), so one could customise the part...
