Usage:
For comparing files created my cairo-perf:
$argv0 old.perf new.perf
For comparing (cached) performance of revisions:
$argv0 [OPTIONS] <revision> [-- cairo-perf options]
$argv0 [OPTIONS] <rev1> <rev2> [-- cairo-perf-options]
If given a single revision, compares its results to that of its
(first-parent) predecessor. Otherwise compares the two given revisions.
The revisions can be any revision accepted by git. For example:
$argv0 HEAD # Show impact of latest commit
$argv0 1.2.0 1.2.4 # Compare performance of 1.2.0 to 1.2.4
Options:
-f, --force
Forces cairo-perf-diff to re-run performance tests
even if cached performance data is available.
-h, --html
With this option performance changes are summarized
as HTML table.
Additional options can be passed the child cairo-perf process
by separating them with a double hyphen (--). For example, to
examine what the impact of the latest change is on the stroke
test you might use:
$argv0 HEAD -- stroke
The performance results are cached in .perf next to the .git directory.
Set CAIRO_AUTOGEN_OPTIONS to pass options to autogen for both
builds.
