Most of the rules inside CTransforms are of the type CMatch.
Don't re-parse the source code every time.
Doing this doesn't change the output, but makes kdoc almost
as fast as before the tokenizer patches:
# Before tokenizer patches
$ time ./scripts/kernel-doc . -man >original 2>&1
real 0m42.933s
user 0m36.523s
sys 0m1.145s
# After tokenizer patches
$ time ./scripts/kernel-doc . -man >before 2>&1
real 1m29.853s
user 1m23.974s
sys 0m1.237s
# After this patch
$ time ./scripts/kernel-doc . -man >after 2>&1
real 0m48.579s
user 0m45.938s
sys 0m0.988s
$ diff -s before after
Files before and after are identical
Manually checked the differences between original and after
with:
$ diff -U0 -prBw original after|grep -v Warning|grep -v "@@"|less
They're due:
- whitespace fixes;
- struct_group are now better handled;
- several badly-generated man pages from broken inline kernel-doc
markups are now fixed.
