* GH-96793: Implement PEP 479 in bytecode. (GH-99006)Mark Shannon2022-11-031-12/+50
| | | | | * Handle converting StopIteration to RuntimeError in bytecode. * Add custom instruction for converting StopIteration into RuntimeError.
* gh-87092: remove unused SET_LOC/UNSET_LOC macros (GH-98914)Irit Katriel2022-11-021-73/+6
|
* gh-87092: do not allocate PyFutureFeatures dynamically (GH-98913)Irit Katriel2022-11-021-12/+10
|
* gh-98811: use full source location to simplify __future__ imports error ↵Irit Katriel2022-10-311-30/+32
| | | | checking. This also fixes an incorrect error offset. (GH-98812)
* GH-96793: Change `FOR_ITER` to not pop the iterator on exhaustion. (GH-96801)Mark Shannon2022-10-271-2/+5
| | | | Change FOR_ITER to have the same stack effect regardless of whether it branches or not. Performance is unchanged as FOR_ITER (and specialized forms jump over the cleanup code).
* gh-98461: Fix location of RETURN_VALUE in async generator bytecode. ↵Irit Katriel2022-10-251-56/+43
| | | | compiler_jump_if no longer needs a pointer to the loc. (GH-98494)
* gh-97912: Avoid quadratic behavior when adding LOAD_FAST_CHECK (GH-97952)Dennis Sweeney2022-10-201-64/+135
| | | | | * The compiler analyzes the usage of the first 64 local variables all at once using bit masks. * Local variables beyond the first 64 are only partially analyzed, achieving linear time.
* gh-98461: Fix source location in comprehensions bytecode (GH-98464)Irit Katriel2022-10-201-60/+74
|
* gh-98398: Fix source locations for 'assert' bytecode (GH-98405)Irit Katriel2022-10-191-8/+10
|

| | | | one place (GH-96513)
* gh-93554: Conditional jump opcodes only jump forward (GH-96318)Irit Katriel2022-09-011-72/+82
|
* gh-93678: apply remove_redundant_jumps in optimize_cfg (GH-96274)Irit Katriel2022-09-011-11/+33
|
* gh-87092: use basicblock_last_instr consistently in the compiler (GH-96243)Irit Katriel2022-08-241-29/+32
|
* gh-93678: add _testinternalcapi.optimize_cfg() and test utils for compiler ↵Irit Katriel2022-08-241-48/+210
| | | | optimization unit tests (GH-96007)

| | | | the compilation unit (GH-95924)
* gh-87092: compiler's codegen stage uses int jump target labels, and the ↵Irit Katriel2022-08-111-70/+52
| | | | target pointer is only calculated just before optimization stage (GH-95655)
* gh-87092: create a 'jump target label' abstraction so that the compiler's ↵Irit Katriel2022-08-041-354/+385

* gh-93678: extract 'struct cfg_builder' from the compiler so that the CFG can ↵Irit Katriel2022-07-261-120/+113

* GH-94694: Fix column offsets for multi-line method lookups (GH-94697)Brandt Bucher2022-07-101-2/+9
|
* gh-92228: disable the compiler's 'small exit block inlining' optimization ↵Irit Katriel2022-07-071-0/+14
| | | | | | | for blocks that have a line number (GH-94592) Inlining of code that corresponds to source code lines, can make it hard to distinguish later between code which is only reachable from except handlers, and that which is reachable in normal control flow. This caused problems with the debugger's jump feature. This PR turns off the inlining optimisation for code which has line numbers. We still inline things like the implicit "return None".
* gh-94485: Set line number of module's RESUME instruction to 0, as specified ↵Irit Katriel2022-07-051-1/+4
