Attached patch enables ASDL parser to construct fields in the right order. It resolves the issue below in Parser/asdl.py # XXX can't I just construct things in the right order? We can safely use left-recursive grammar since Parser/spark.py implements Earley parser. The patch doesn't affect Python-ast.[ch] as expected. $ make Include/Python-ast.h Python/Python-ast.c $ diff -s ~/test/Python-ast.h Include/Python-ast.h Files /home/xenosoz/test/Python-ast.h and Include/Python-ast.h are identical $ diff -s ~/test/Python-ast.c Python/Python-ast.c Files /home/xenosoz/test/Python-ast.c and Python/Python-ast.c are identical Time consumption before/after the patch: -- before patch -- time make Include/Python-ast.h real 0m0.578s \ user 0m0.500s \ sys 0m0.060s time make Python/Python-ast.c real 0m0.687s \ user 0m0.620s \ sys 0m0.050s -- after patch -- $ time make Include/Python-ast.h real 0m0.588s \ user 0m0.510s \ sys 0m0.060s $ time make Python/Python-ast.c real 0m0.677s \ user 0m0.630s \ sys 0m0.030s It touches: Misc/ACKS Parser/asdl.py |
