* GH-89987: Shrink the BINARY_SUBSCR caches (GH-103022)Brandt Bucher2023-03-291-191/+191
|
* GH-100982: Break up COMPARE_AND_BRANCH (GH-102801)Brandt Bucher2023-03-231-240/+213
|
* gh-102859: Remove JUMP_IF_FALSE_OR_POP and JUMP_IF_TRUE_OR_POP (#102870)Irit Katriel2023-03-221-176/+114

* GH-101291: Rearrange the size bits in PyLongObject (GH-102464)Mark Shannon2023-03-221-387/+386
| | | | | | | | | | * Eliminate all remaining uses of Py_SIZE and Py_SET_SIZE on PyLongObject, adding asserts. * Change layout of size/sign bits in longobject to support future addition of immortal ints and tagged medium ints. * Add functions to hide some internals of long object, and for setting sign and digit count. * Replace uses of IS_MEDIUM_VALUE macro with _PyLong_IsCompact().
* gh-102598: Remove obsolete optimization from `FORMAT_VALUE` opcode (#102599)Nikita Sobolev2023-03-211-30/+17

* gh-102192: Replace PyErr_Fetch/Restore etc by more efficient alternatives ↵Irit Katriel2023-03-191-321/+317

* gh-102654: Insert #line directives in generated_cases.c.h (#102669)Guido van Rossum2023-03-151-0/+456
| | | | | | | | | This behavior is optional, because in some extreme cases it may just make debugging harder. The tool defaults it to off, but it is on in Makefile.pre.in. Also note that this makes diffs to generated_cases.c.h noisier, since whenever you insert or delete a line in bytecodes.c, all subsequent #line directives will change.
