Demur Rumed added the comment: Perhaps BUILD_CONST_KEY_MAP?
Ideally the opcode could ellide the LOAD_CONST for the tuple. ie have LOAD_CONST 2 (1, 2, 3), BUILD_CONST_KEY_MAP 3 be BUILD_CONST_KEY_MAP 2 (1, 2, 3). However that'd require stack_effect to somehow lookup the const tuple Thinking to in the context of MAKE_FUNCTION, I'd like to create a function for ceval which takes stack_pointer & returns stack_pointer at new offset with dict at top of stack. Then use this both for this opcode & have MAKE_FUNCTION call it directly (ie, don't have to emit BUILD_MAP_EX). This too makes for a need to do some backtracking to figure out stack effect Relying on the peepholer seems unideal; it does more work than generating the tuple the first time & doing it eagerly will produce a more compact stack depth & co_consts ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27140> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
