New submission from Mark Shannon <m...@hotpy.org>:
The RESUME instruction was added to make resumption points explicit in the bytecode. This makes it easier to implement tracing, quickening, and interrupt checks as there is an explicit place to perform these checks. Unfortunately, it also has considerable overhead. So we should remove it. To do that, we need to: 1. Remove f_state from the InterpreterFrame so we don't need to update it. 2 .Quicken automatically in the adaptive instructions. 3. Check the evalbreaker when resuming a frame in the interpreter. 4. Add some metadata to the code object, so that we know when to fire "call" events when tracing. ---------- assignee: Mark.Shannon messages: 415424 nosy: Mark.Shannon priority: normal severity: normal status: open title: Remove the RESUME instruction type: performance _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue47045> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
