Rollup merge of #82532 - pnkfelix:rustbuild-print-step-rusage, r=Mark-Simulacrum
Add `build.print_step_rusage` to config.toml Adds `build.print_step_rusage` to config.toml, which is meant to be an easy way to let compiler developers get feedback on the terminal during bootstrap about resource usage during each step. The output is piggy-backed on `[PRINT-STEP-TIMINGS]`, mostly because the functionality seemed to naturally fit there in the overall control-flow and output structure (even if very little is shared between the implementations themselves). Some sample output (from my Linux box, where I believe the `max rss` output to be somewhat trust-worthy...): ``` [...] Compiling regex v1.4.3 [RUSTC-TIMING] tempfile test:false 0.323 user: 1.418662 sys: 0.81767 max rss (kb): 182084 page reclaims: 26615 page faults: 0 fs block inputs: 0 fs block outputs: 2160 voluntary ctxt switches: 798 involuntary ctxt switches: 131 Completed tempfile v3.1.0 in 0.3s [RUSTC-TIMING] chalk_ir test:false 1.890 user: 1.893603 sys: 0.99663 max rss (kb): 239432 page reclaims: 32107 page faults: 0 fs block inputs: 0 fs block outputs: 25008 voluntary ctxt switches: 108 involuntary ctxt switches: 183 Completed chalk-ir v0.55.0 in 1.9s Compiling rustc_data_structures v0.0.0 (/home/pnkfelix/Dev/Rust/rust.git/compiler/rustc_data_structures) [RUSTC-TIMING] chrono test:false 1.244 user: 3.333198 sys: 0.134963 max rss (kb): 246612 page reclaims: 44857 page faults: 0 fs block inputs: 0 fs block outputs: 11704 voluntary ctxt switches: 1043 involuntary ctxt switches: 326 Completed chrono v0.4.15 in 1.3s [RUSTC-TIMING] rustc_rayon test:false 1.332 user: 1.763912 sys: 0.75996 max rss (kb): 239076 page reclaims: 35285 page faults: 0 fs block inputs: 0 fs block outputs: 19576 voluntary ctxt switches: 359 involuntary ctxt switches: 168 Completed rustc-rayon v0.3.0 in 1.3s Compiling matchers v0.0.1 [RUSTC-TIMING] matchers test:false 0.100 user: 0.94495 sys: 0.15119 max rss (kb): 140076 page reclaims: 8200 page faults: 0 fs block inputs: 0 fs block outputs: 392 voluntary ctxt switches: 43 involuntary ctxt switches: 12 Completed matchers v0.0.1 in 0.1s [...] ```
