New submission from Serhiy Storchaka: This is the second stage of converting to wordcode (issue26647).
Proposed patch makes bytecodecode consisting of code units (16-bit words) instead of bytes. It includes following changes: * Changes meaning of jump offsets. They counts not bytes, but code units. This extends the range addressed by short commands (from 256 bytes to 256 words) and simplifies ceval.c. * Changes f_lasti, tb_lasti etc to count code units instead of bytes. * Changes disassembler to show addresses in code units, not bytes. * Refactores the code. These changes break compatibility (already broken by switching to 16-bit bytecode). The first one breaks compatibility with compiled bytecode and needs incrementing the magic number. ---------- components: Interpreter Core files: wordcode2.patch keywords: patch messages: 266431 nosy: haypo, serhiy.storchaka priority: normal severity: normal stage: patch review status: open title: Wordcode, part 2 type: enhancement versions: Python 3.6 Added file: http://bugs.python.org/file43015/wordcode2.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27129> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
