Martin Panter added the comment: I’m not sure I understand your questions Brett (Which tokenizer? What rebuilding?), but I will try to explain some relevant parts.
My main goal is to add a makefile dependency of parsetok.o on $(GRAMMAR_H). In Python 3, that is easy, and (I realize now) my problem would be solved without changing any other file. However my changes in parsetok.c eliminate an unnecessary bootstrapping problem, so I still think they are worthwhile. For Python 3, the parsetok.c code gets compiled to parsetok_pgen.o, and after executing, also gets compiled to a separate parsetok.o file. Rebuilding the code is not a problem here. In Python 2, the same parsetok.o object is both part of the pgen program, and the eventual Python program. In order to add my desired makefile dependency, I have to duplicate parsetok.c compilation into two makefile rules (parsetok.o and parsetok_pgen.o). So you could say I am breaking a circle _by_ rebuilding the code. Dependencies between files with my patch applied: Parser/parsetok_pgen.o -> Parser/pgen -> Include/graminit.h -> Parser/parsetok.o -> python ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4347> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
