Constant folding:
- Add string/bytes multiply and bytes concat folding in IR
- Add constant subscript folding (str, bytes, tuple indexing)
- Delegate list/set constant folding to IR passes
- Stream big non-const list/set via BUILD+LIST_APPEND
Class/generic compilation:
- Reorder class body prologue: __type_params__ before __classdict__
- Build class function before .generic_base in generic classes
- Register .type_params/.generic_base symbols in proper scopes
- Use load_name/store_name helpers for synthetic variables
Return block handling:
- Only duplicate return-None epilogues, not arbitrary returns
- Add inline_pop_except_return_blocks pass
- Add duplicate_named_except_cleanup_returns pass
Other fixes:
- Fix eliminate_dead_stores to only collapse adjacent duplicates
- Skip STORE_FAST_LOAD_FAST superinstruction in generators after FOR_ITER
- Thread jumps through NOP-only blocks
- Transfer NOP line info to following unconditional jumps
- Extract scope_needs_conditional_annotations_cell helper
- Register __conditional_annotations__ for module future annotations
This directory contains all of the Python files that make up the standard
library for RustPython.
Most of these files are copied over from the CPython repository (the 3.7
branch), with slight modifications to allow them to work under RustPython. The
current goal is to complete the standard library with as few modifications as
possible. Current modifications are just temporary workarounds for bugs/missing
feature within the RustPython implementation.
The first big module we are targeting is unittest, so we can leverage the
CPython test suite.
