wazabin-pcode

Shared vocabulary and source-shaped SLEIGH p-code AST types for producers and consumers. It covers address spaces, registers, expression and statement ASTs, operators, builtins, diagnostics, and user-defined operation identifiers.

Developed by Thalium.

Scope

PcodeAst models the p-code written in a SLEIGH semantic section. It preserves nested expressions and source constructs such as macro, build, export, and delayslot.

InstructionPcode models Ghidra's flat PcodeOp/varnode instruction IR. The crate exposes lower_instruction and PcodeLoweringContext, the producer-supplied specification information required by the AST-to-operations lowerer. The initial raw lowerer covers expanded scalar expressions, memory, userops, and control flow; named and source bit ranges are rejected until their raw-op expansion is implemented.

PcodeAst::pretty_print is producer-independent through PcodeResolver. A SLEIGH compiler supplies the resolver, so this crate has no dependency on a decoder implementation.
