Pcode Parser

Parser for raw (low-level) Pcode generated from Ghidra, written in Rust.

Example in main.rs

The program parses a Pcode program like this one:

0x400f9c
(unique,0x5380,1) = LOAD (const,0x55706c52be80,8) (register,0x0,8)
(register,0x200,1) = INT_CARRY (unique,0x5380,1) (register,0x0,1)
[...]
0x400f9e

as follows:

Address: 0x400f9c
Inst { opcode: Load, output: Some(Varnode { var: Unique(0x5380), size: Byte }), inputs: [Varnode { var: Const("0x5643218c0ff0"), size: Quad }, Varnode { var: Register(0), size: Quad }] }
Inst { opcode: IntCarry, output: Some(Varnode { var: Register(200), size: Byte }), inputs: [Varnode { var: Unique(0x5380), size: Byte }, Varnode { var: Register(0), size: Byte }] }
[...]
Address: 0x400f9e

Usage

You can generate the raw Pcode of a binary using Pcode-generator and then use Pcode-parser to parse the produced pcode.
