Message-ID: Let me correct myself, it looks like there is in fact a user range of opcodes. Seems adding a language code at this time is not yet needed. I will use that instead for now. I will send out preliminary patches for LLDB and GDB symbol de-mangling when I have a preliminary experimental release ready. Currently the symbol format is unstable so adding de-mangling for multiple code styles is not warranted. GCC support is not planned as I have my hands full with LLVM already. -- Ryan P.
