implement detail_exit but I'm not sure it is right. not create new file and write detail exit in lib.rs replace std::process::exit to detail_exit that is not related to code runnning. remove pub

2022-05-28Rollup merge of #97411 - raiyansayeed:print-stderr-consistently, ↵Matthias Krüger-4/+4
r=Mark-Simulacrum Print stderr consistently Solves https://github.com/rust-lang/rust/issues/96712 I tried to follow what I perceived as the general consensus for error messages in boostrap i.e messages that were .. * resulting from an Err(...) => * literally called as "Error: ...." * by the end of the block scope forced to run a panic! or process::exit with a guaranteed non-zero error code.

2022-05-10Add test skip supportCollin Baker-2/+19
libtest already supports a "--skip SUBSTRING" arg which excludes any test names matching SUBSTRING. This adds a "--skip" argument to compiletest and bootstrap which is forwarded to libtest.
2022-04-21Add a test for `--exclude test::XXX`Joshua Nelson-0/+20
I didn't know that the `test::` syntax was valid before, and it doesn't seem to be documented anywhere. Add a test so it doesn't regress accidentally, and as executable documentation.
2022-04-16bootstrap: consolidate subcommand parsing and matchingAllen Wild-76/+50
There's several places where the x.py command names are matched as strings, leading to some inconsistencies and opportunities for cleanup. * Add Format, Clean, and Setup variants to builder::Kind. * Use Kind to parse the x.py subcommand name (including aliases) * Match on the subcommand Kind rather than strings when handling options and help text. * Several subcommands don't display any paths when run with `-h -v` even though the help text indicates that they should. Fix this and refactor so that manually keeping matches in sync isn't necessary. Fixes #95937
2022-03-07copy over `std::path::absolute` instead of adding `canonicalize` hacksJoshua Nelson-1/+1
this also fixes a bug where bootstrap would try to use the fake `rustc` binary built by bootstrap - cargo puts it in a different directory when using `cargo run` instead of x.py

2022-03-05Merge build_helper into utilbjorn3-1/+1
2022-03-05Remove build_helperbjorn3-1/+1
The majority of the code is only used by either rustbuild or rustc_llvm's build script. Rust_build is compiled once for rustbuild and once for every stage. This means that the majority of the code in this crate is needlessly compiled multiple times. By moving only the code actually used by the respective crates to rustbuild and rustc_llvm's build script, this needless duplicate compilation is avoided.

They're a bit out of date, and overly complicated.
2021-08-24PGO for LLVM builds on x86_64-unknown-linux-gnu in CIMark Rousskov-2/+18
This shows up to 5% less instruction counts on multiple benchmarks, and up to 19% wins on the -j1 wall times for rustc self-compilation. We can afford to spend the extra cycles building LLVM essentially once more for the x86_64-unknown-linux-gnu CI build today. The builder finishes in around 50 minutes on average, and this adds just 10 more minutes. Given the sizeable improvements in compiler performance, this is definitely worth it.
2021-08-13Enable `--all-targets` for `x.py check` unconditionallyJoshua Nelson-4/+6
Now that Cargo deduplicates diagnostics from different targets, this doesn't flood the console with duplicate errors. Note that this doesn't add `--all-targets` in `Builder::cargo` directly because `impl Step for Std` actually wants to omit `--all-targets` the first time while it's still building libtest. When passed `--all-targets`, this warns that the option isn't needed, but still continues to compile.

2020-12-22Utilize PGO for rustc linux dist buildsMark Rousskov-0/+7
This implements support for applying PGO to the rustc compilation step (not standard library or any tooling, including rustdoc). Expanding PGO to more tools is not terribly difficult but will involve more work and greater CI time commitment. For the same reason of avoiding greater time commitment, this currently avoids implementing for platforms outside of x86_64-unknown-linux-gnu, though in practice it should be quite simple to extend over time to more platforms. The initial implementation is intentionally minimal here to avoid too much work investment before we start seeing wins for a subset of Rust users. The choice of workloads to profile here is somewhat arbitrary, but the general rationale was to aim for a small set that largely avoided time regressions on perf.rust-lang.org's full suite of crates. The set chosen is libcore, cargo (and its dependencies), and a few ad-hoc stress tests from perf.rlo. The stress tests are arguably the most controversial, but they benefit those cases (avoiding regressions) and do not really remove wins from other benchmarks. The primary next step after this PR lands is to implement support for PGO in LLVM. It is unclear whether we can afford a full LLVM rebuild in CI, though, so the approach taken there may need to be more staggered. rustc-only PGO seems well affordable on linux at least, giving us up to 20% wall time wins on some crates for 15 minutes of extra CI time (1 hour up from 45 minutes). The PGO data is uploaded to allow others to reuse it if attempting to reproduce the CI build or potentially, in the future, on other platforms where an off-by-one strategy is used for dist builds at minimal performance cost.

2020-09-26Rollup merge of #76631 - jyn514:x.py-setup, r=Mark-SimulacrumRalf Jung-1/+31
Add `x.py setup` Closes #76503. - Suggest `x.py setup` if config.toml doesn't exist yet - Prompt for a profile if not given on the command line - Print the configuration that will be used - Print helpful starting commands after setup - Link to the dev-guide after finishing
2020-09-24Add `x.py setup`Joshua Nelson-1/+31
- Suggest `x.py setup` if config.toml doesn't exist yet (twice, once before and once after the build) - Prompt for a profile if not given on the command line - Print the configuration file that will be used - Print helpful starting commands after setup - Link to the dev-guide after finishing - Note that distro maintainers will see the changelog warning
2020-09-23Add `keep-stage-std` to `x.py`Dylan MacKenzie-1/+16
This keeps only the `std` artifacts compiled by the given stage, not the compiler. This is useful when working on the latter stages of the compiler in tandem with the standard library, since you don't have to rebuild the *entire* compiler when the standard library changes.
2020-09-16Don't generate bootstrap usage unless it's neededJoshua Nelson-30/+32
Previously, `x.py` would unconditionally run `x.py build` to get the help message. After https://github.com/rust-lang/rust/issues/76165, when checking the CI stage was moved into `Config`, that would cause an assertion failure (but only only in CI!): ``` thread 'main' panicked at 'assertion failed: `(left == right)` left: `1`, right: `2`', src/bootstrap/config.rs:619:49 ``` This changes bootstrap to only generate a help message when it needs to (when someone passes `--help`).
2020-09-11Stop implicitly appending triples to config.toml hosts and targetsMark Rousskov-10/+22
Previously, the CLI --target/--host definitions and configured options differed in their effect: when setting these on the CLI, only the passed triples would be compiled for, while in config.toml we would also compile for the build triple and any host triples. This is needlessly confusing; users expect --target and --host to be identical to editing the configuration file. The new behavior is to respect --host and --target when passed as the *only* configured triples (no triples are implicitly added). The default for --host is the build triple, and the default for --target is the host triple(s), either configured or the default build triple.
