This PR replaces all usages of `[:]` slice notation in `src` with the new `[...]` notation in production code, tests and comments. The underlying implementation of the `Subarray` functions stays the same. Notation cheat sheet: * `*...*` is the doubly-unbounded range. * `*...a` or `*...<a` contains all elements that are less than `a`. * `*...=a` contains all elements that are less than or equal to `a`. * `a...*` contains all elements that are greater than or equal to `a`. * `a...b` or `a...<b` contains all elements that are greater than or equal to `a` and less than `b`. * `a...=b` contains all elements that are greater than or equal to `a` and less than or equal to `b`. * `a<...*` contains all elements that are greater than `a`. * `a<...b` or `a<...<b` contains all elements that are greater than `a` and less than `b`. * `a<...=b` contains all elements that are greater than `a` and less than or equal to `b`. Benchmarks have shown that importing the iterator-backed parts of the polymorphic slice library in `Init` impacts build performance. This PR avoids this problem by separating those parts of the library that do not rely on iterators from those those that do. Whereever the new slice notation is used, only the iterator-independent files are imported. |

Lean Benchmark Suites
This folder contains multiple small Lean programs for benchmarking used by two separate benchmark suites based on the temci benchmarking tool:
- The light-weight "Speedcenter" suite benchmarks the current build of Lean. It can be used for quick comparisons on the cmdline and powers the Lean Speedcenter website.
- The heavy-weight "Cross" suite benchmarks multiple Lean configurations and other functional compilers against each other and generates CSV and HTML reports from that. It was created for the paper "Counting Immutable Beans - Reference Counting Optimized for Purely Functional Programming" (IFL19).
Speedcenter Suite
Requirements:
- A local Lean build in
../../build/release. Build at least thebintarget. - temci. Using Nix, open a nix-shell in the project
root directory to add a compatible version to your PATH. Alternatively, try
pip3 install git+https://github.com/parttimenerd/temci.git.
To execute the suite and save the results in base.yaml, run (in this folder)
temci exec --config speedcenter.yaml --out base.yaml
Other interesting exec flags:
- use
--runs Nto modify the default number of 10 runs per benchmark - use
--included_blocks fastto excluded slow benchmarks like the stdlib benchmark. You can replacefastwith any benchmark name or label inspeedcenter.exec.yaml.
If you have multiple saved result files, you can compare them with
temci report --config speedcenter.yaml report1.yaml report2.yaml ...
Cross Suite
We recommend using Nix for building/obtaining all Lean variants and used compilers in a reproducible way. After installing Nix, running the benchmarks is as easy as
nix develop
make
This will record 50 runs for each benchmark configuration (this can be changed with runs in cross.yaml),
generate results in report_lean.csv and report_cross.csv, and print them to stdout in a tabulated format.
It will also generate HTML reports in report/ comparing the time-based benchmarks.
In order to reduce noise in the benchmarking data, you may instead want to try calling make inside a
temci shell:
temci short shell --sudo --preset usable --cpuset_active make
Using root powers, this will temporarily configure your machine similarly to the LLVM benchmarking recommendations and move all your other processes to a single CPU core.
