      --dump-bootstrap-shims
          Indicates whether to dump the work done from bootstrap shims
      --stage <N>
          stage to build (indicates compiler to use/test, e.g., stage 0 uses the bootstrap compiler, stage 1 the stage 0 rustc artifacts, etc.)
      --keep-stage <N>
          stage(s) to keep without recompiling (pass multiple times to keep e.g., both stages 0 and 1)
      --keep-stage-std <N>
          stage(s) of the standard library to keep without recompiling (pass multiple times to keep e.g., both stages 0 and 1)
      --src <DIR>
          path to the root of the rust checkout
  -j, --jobs <JOBS>
          number of jobs to run in parallel
      --warnings <deny|warn>
          if value is deny, will deny warnings if value is warn, will emit warnings otherwise, use the default configured behaviour [default: default] [possible values: deny, warn, default]
      --json-output
          use message-format=json
      --compile-time-deps
          only build proc-macros and build scripts (for rust-analyzer)
      --color <STYLE>
          whether to use color in cargo and rustc output [default: auto] [possible values: always, never, auto]
      --bypass-bootstrap-lock
          Bootstrap uses this value to decide whether it should bypass locking the build process. This is rarely needed (e.g., compiling the std library for different targets in parallel)
      --rust-profile-generate <PROFILE>
          generate PGO profile with rustc build
      --rust-profile-use <PROFILE>
          use PGO profile for rustc build
      --llvm-profile-use <PROFILE>
          use PGO profile for LLVM build
      --llvm-profile-generate
          generate PGO profile with llvm built for rustc
      --enable-bolt-settings
          Enable BOLT link flags
      --skip-stage0-validation
          Skip stage0 compiler validation
      --reproducible-artifact <REPRODUCIBLE_ARTIFACT>

      --skip-std-check-if-no-download-rustc
          Skip checking the standard library if `rust.download-rustc` isn't available. This is mostly for RA as building the stage1 compiler to check the library tree on each code change might be too much for some computers
  -h, --help
          Print help (see more with '--help')
