New submission from Thomas Anderson <tom...@gmail.com>:
Currently the block stack size is hardcoded to 20. Similar to how the value stack is dynamically sizable, we should make the block stack dynamically sizable. This will reduce space on average (since the typical number of blocks for a function is well below 20) and allow code generators to generate code with more deep nesting. Note: the motivation is not necessarily to reduce memory usage, but to make L1 cache misses less likely for stack objects. ---------- components: Interpreter Core messages: 384991 nosy: tomkpz priority: normal severity: normal status: open title: Block stack size for frame objects should be dynamically sizable type: enhancement versions: Python 3.10 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42917> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
