In a repository with many refs, check_refname_component can be a major
contributor to the runtime of some git commands. One such command is
git rev-parse HEAD
Timings for one particular repo, with about 60k refs, almost all
packed, are:
Old: 35 ms
New: 29 ms
Many other commands which read refs
Optimize check_refname_component using SSE4.2, where available.
git rev-parse HEAD is a good test-case for this, since it does almost
nothing except parse refs. For one particular repo with about 60k
refs, almost all packed, the timings are:
Look up table: 29 ms
SSE4.2:25 ms
This is abo

I intended it resend the series after the comments I received, but it
looks like Junio has picked up all comments except this one, so
here's the fix.
sequencer.c | 2 +-
1 file changed, 1 insertion(+), 1 deletion(-)
diff --git a/sequencer.c b/sequencer

Instead of calling git-archive HEAD^{tree}, use $(GIT_VERSION)^{tree}.
This makes sure the archive name and contents are consistent, if HEAD
has moved, but GIT-VERSION-FILE hasn't been regenerated yet.

Discard the unnecessary 'nr_spaces' variable, remove 'strlen()' and
improve the 'if' structure. Switch to pointers instead of integers
Slightly more rare occurrences of 'text \' with a backslash
in between spaces are handled correctly. Namely, the code in
8ba87adad6 does not reset 'last_space

This is such an useful notion that I can fathom why there isn't a better,

I'm 100% in agreement. "Reset current branch to X" is an extremely
common operation, and I use this all the time. But having to
