* Add timing scriptsGravatar Jason Gross2017-07-11
This commit adds timing scripts from https://github.com/JasonGross/coq-scripts/tree/master/timing into the tools folder, and integrates them into coq_makefile and Coq's makefile. The main added makefile targets are: - the `TIMING` variable - when non-empty, this creates for each built `.v` file a `.v.timing` variable (or `.v.before-timing` or `.v.after-timing` for `TIMING=before` and `TIMING=after`, respectively) - `pretty-timed TGTS=...` - runs `make $(TGTS)` and prints a table of sorted timings at the end, saving it to `time-of-build-pretty.log` - `make-pretty-timed-before TGTS=...`, `make-pretty-timed-after TGTS=...` - runs `make $(TGTS)`, and saves the timing data to the file `time-of-build-before.log` or `time-of-build-after.log`, respectively - `print-pretty-timed-diff` - prints a table with the difference between the logs recorded by `make-pretty-timed-before` and `make-pretty-timed-after`, saving the table to `time-of-build-both.log` - `print-pretty-single-time-diff BEFORE=... AFTER=...` - this prints a table with the differences between two `.v.timing` files, and saves the output to `time-of-build-pretty.log` - `*.v.timing.diff` - this saves the result of `print-pretty-single-time-diff` for each target to the `.v.timing.diff` file - `all.timing.diff` (`world.timing.diff` and `coq.timing.diff` in Coq's own Makefile) - makes all `*.v.timing.diff` targets N.B. We need to make `make pretty-timed` fail if `make` fails. To do this, we need to get around the fact that pipes swallow exit codes. There are a few solutions in https://stackoverflow.com/questions/23079651/equivalent-of-pipefail-in-gnu-make; we choose the temporary file rather than requiring the shell of the makefile to be bash.
