* typealias reviews
* Bytecode parity - try/except block order, CFG reorder
Reorder try/except/else/finally to emit else+finally before
except handlers matching CPython layout. Add set_no_location
for cleanup blocks. Extend CFG reorder pass to handle true-path
jump-back for generators, break/continue, and assert in loops.
Add stop-iteration error handler awareness to block protection.
* Align CFG cleanup bytecode with CPython
* Unmark test_dis.test_findlabels expected failure
* Compute target predecessor flags in single pass
remove_nops and remove_redundant_nops_in_blocks repeated
has_jump_predecessor / has_plain_jump_predecessor / target lookups
per block, scanning all blocks each time. With ~200,000 if blocks
this became O(B^2 * I) and timed out test_compile.test_stack_overflow.
Fold the three flags into one O(B * I) pass via
compute_target_predecessor_flags.
* Address review feedback on slice folding, fallthrough, attr-chain
- try_fold_constant_slice now delegates to try_fold_constant_expr so
slice bounds accept the same constants other folding paths do
(unary-folded values, __debug__, etc.).
- remove_nops resolves fallthrough predecessors through empty blocks
via next_nonempty_block before checking ends_with_for_cleanup.
- should_deopt_borrowed_attr_chain ReturnIter matcher now accepts
Instruction::CallKw alongside Instruction::Call, matching the
Call/CallKw treatment in the surrounding deopt trigger check.
* remove test
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.
