Support demangling SYM names

subj.

It will be a hard task, and I don't see any benefits in implementing it.

Its apparently some version of GCC mangling cause IDA can demangle these if the "Assume GCC 3.x names" is unchecked, so maybe Ghidra might support it with some setting too given it has a GCC demangler?

[lab313ru]

Hmm, good idea. I'll try.

[tomsons26]

ghidra\GPL\DemanglerGnu\os\win64\demangler_gnu.exe ChangeTPage__FPUsi
outputs ChangeTPage(unsigned short *, int) so yea it's demangler can do it, seems its treated as old gnu format then.

[lab313ru]

Demangler works by default, as I know.

[tomsons26]

hm, Ghidra's code might be failing here, https://github.com/NationalSecurityAgency/ghidra/blob/master/Ghidra/Features/Base/src/main/java/ghidra/app/cmd/label/DemanglerCmd.java#L55
seems it would have to just try them all until it demangles it but it doesn't

don't see a way to pass a demangler style to DemanglerCmd either..

I have an implementation in the works for https://github.com/beardypig/ghidra-emotionengine
If you'd like I can separate it into it's own plugin if this helps. It will handle some custom metrowerks mangled symbols too.

The only problem is an additional native process is required to set the demangler mode.

It would be great for me to use your demangling code in my plugin so it will be still a single plugin, not multiple. Is it possible?

I wouldn't mind. I have to clean some stuff up first. In reality it would only be temporary anyway until the issue is dealt with in ghidra.
