Module codegen_python 

Shared Python code generation helpers.

Provides reusable functions for emitting Python code from the chipi IR. Used by the IDA backend (and future Binary Ninja backend).

Structs

DisplayConfig

Configuration for display formatting in generated Python code.

Functions

apply_transforms_python

Apply chipi transforms to a Python expression.

emit_decode_function

Generate the Python _decode(data) function body using the decision tree.

emit_display_format_helpers

Emit _fmt_signed_hex and _fmt_hex helper functions if needed.

emit_format_function

Generate the _format_insn(itype, fields) Python function. Returns (mnemonic_str, operands_str).

emit_guard_python

Generate a Python guard condition from a Guard.

emit_map_functions_python

Generate Python dict-based map (lookup) functions.

emit_rotate_helpers

Emit a _rotate_right(val, amt, width) Python helper function.

emit_sign_extend_helper

Emit a _sign_extend(val, bits) Python helper function.

emit_subdecoder_python

Generate a Python sub-decoder dispatch function.

escape_python_fstr

Escape a string for use inside Python f-string literals.

escape_python_str

Escape a string for use inside Python string literals.

expr_to_python

Convert a FormatExpr to a Python expression string.

extract_expr_python

Generate a Python expression to extract bits from ranges.

format_pieces_to_python_expr

Convert format pieces to a Python expression (concatenated string). fields_var is the variable name for the fields dict (e.g., “fields”).

leaf_guard_python

Compute a guard condition for a leaf node in Python. Returns None if no guard is needed.

needs_rotate_helpers

Check if any instruction uses rotate builtins.

needs_sign_extend

Check if any instruction uses sign_extend transforms.

to_snake_case

Convert a name to snake_case.
