benchproc: correctly parse signed numeric sort keys The regular expression used by parseNum did not include an optional sign and was not anchored to the input. As a result, a value such as "-1k" was parsed as positive 1000, while strings such as "abc1Mxyz" and "1kB/s" were accepted by extracting a numeric substring. Anchor the suffixed-number expression and include an optional leading sign. Continue to use strconv.ParseFloat to validate the numeric portion. Add tests for signed SI and IEC values and for rejecting inputs with unrelated prefixes or suffixes.

This subrepository holds tools and packages for analyzing Go benchmark results, such as the output of testing package benchmarks.
This subrepository contains command-line tools for analyzing benchmark result data.
cmd/benchstat computes statistical summaries and A/B comparisons of Go benchmarks.
cmd/benchfilter filters the contents of benchmark result files.
cmd/benchsave publishes benchmark results to perf.golang.org.
To install all of these commands, run go install golang.org/x/perf/cmd/...@latest. You can also git clone https://go.googlesource.com/perf and run go install ./cmd/... in the checkout.
Underlying the above tools are several packages for working with benchmark data. These are designed to work together, but can also be used independently.
benchfmt reads and writes the Go benchmark format.
benchunit manipulates benchmark units and formats numbers in those units.
benchproc provides tools for filtering, grouping, and sorting benchmark results.
benchmath provides tools for computing statistics over distributions of benchmark measurements.
The following packages are deprecated and no longer supported:
storage contains a deprecated version of the https://perfdata.golang.org/ benchmark result storage system. These packages have moved to https://golang.org/x/build.
analysis contains a deprecated version of the https://perf.golang.org/ benchmark result analysis system. These packages have moved to https://golang.org/x/build.
