gh-87092: do not allocate PyFutureFeatures dynamically (GH-98913) 2022-11-02 15:13:07 +00:00

gh-98811: use full source location to simplify __future__ imports error checking. This also fixes an incorrect error offset. (GH-98812) 2022-10-31 13:08:03 +00:00

GH-96793: Change `FOR_ITER` to not pop the iterator on exhaustion. (GH-96801) 
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. compiler_jump_if no longer needs a pointer to the loc. (GH-98494) 2022-10-25 12:26:26 +01:00

gh-97912: Avoid quadratic behavior when adding LOAD_FAST_CHECK (GH-97952) 
* 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-87092: compiler's codegen stage uses int jump target labels, and the target pointer is only calculated just before optimization stage (GH-95655) 2022-08-11 17:40:49 +01:00
Irit Katriel 000c3874bf
gh-87092: create a 'jump target label' abstraction so that the compiler's codegen stage does not work directly with basic blocks (GH-95398) 2022-08-04 14:59:32 +01:00

gh-92228: disable the compiler's 'small exit block inlining' optimization 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".
