Ken Jin	e0d6500b2d	gh-136125: Use _PyObject_GetMethodStackRef for LOAD_ATTR (GH-136127)	2025-07-02 01:20:46 +08:00
Ken Jin	695ab61351	gh-132732: Automatically constant evaluate pure operations (GH-132733) ... This adds a "macro" to the optimizer DSL called "REPLACE_OPCODE_IF_EVALUATES_PURE", which allows automatically constant evaluating a bytecode body if certain inputs have no side effects upon evaluations (such as ints, strings, and floats).
