After a run, it can be useful to reprint the results, so add cairo-perf-print to perform that task. For the future, I'd like to move the performance suite over to the git/perf style of single, multi-function binary. The sequence of operations that I typically do are: ./cairo-perf-trace -r -v -i 6 > `git describe`.`hostname`.perf ./cairo-perf-diff-files REVA REVB ./cairo-perf-print REVA ./cairo-perf-compare-backends REVA which misses the caching available with cairo-perf-diff. 'make html' is almost what I want, but still too prescriptive. However, that does need to be addressed for continuous performance monitoring. Along the perf lines, those sequence of operations become: ./cairo-perf record -i 6 ./cairo-perf report ./cairo-perf report REVA REVB ./cairo-perf report --backends="image,xlib,gl" REVA REVB ./cairo-perf report --html REVA REVB Also we want to think about installing the cairo-perf binary. So we want to differentiate when run inside a git checkout.
