High level P-Code

[dzonerzy]

I'm trying to hack around with p-code there are a lot of projects which make use of ghidra sleigh library to lift asm code to p-code but I was wonder why there's no library that provide high level p-code I know that that's up to the decompiler that first transform p-code to SSA and then apply various optimizations and finally lift it to high level p-code, any chance someone can point out where that's happen in the ghidra's decompiler code? I know about heritage.cc which should transform the p-code to SSA but what about the other steps?
