Bug ID: 107613
Summary: sphinx-build is slow for gccint manual
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: burnus at gcc dot gnu.org
Target Milestone: ---
I noticed the manual build takes quite some time (~90 seconds):
$ /usr/bin/sphinx-build -b texinfo -d
/dev/shm/objdir/gcc/doc/gccint/info/doctrees
/home/marxin/Programming/gcc/gcc/doc/gccint
/dev/shm/objdir/gcc/doc/gccint/info/texinfo -j auto
...
resolving references...
Apparently, when I look at the cProfile I get something like:
Ordered by: cumulative time
List reduced from 5417 to 60 due to restriction <60>
ncalls tottime percall cumtime percall filename:lineno(function)

/usr/lib/python3.10/site-packages/sphinx/domains/cpp.py:4050(get_newest_id)
So 55 seconds are spent in cpp domain direct_lookup function.
We've got ~1000 C++ function defines and so let me report that to upstream.
