2020-07-17Teach bootstrap about target files vs target triplesJake Goulding-6/+5
`rustc` allows passing in predefined target triples as well as JSON target specification files. This change allows bootstrap to have the first inkling about those differences. This allows building a cross-compiler for an out-of-tree architecture (even though that compiler won't work for other reasons). Even if no one ever uses this functionality, I think the newtype around the `Interned<String>` improves the readability of the code.
2020-06-19Rollup merge of #73352 - ehuss:bootstrap-metadata, r=Mark-SimulacrumRalf Jung-5/+2
Speed up bootstrap a little. The bootstrap script was calling `cargo metadata` 3 times (or 6 with `-v`). This is a very expensive operation, and this attempts to avoid the extra calls. On my system, a simple command like `./x.py test -h -v` goes from about 3 seconds to 0.4. An overview of the changes: - Call `cargo metadata` only once with `--no-deps`. Optional dependencies are filtered in `in_tree_crates` (handling `profiler_builtins` and `rustc_codegen_llvm` which are driven by the config). - Remove a duplicate call to `metadata::build` when using `-v`. I'm not sure why it was there, it looks like a mistake or vestigial from previous behavior. - Remove check for `_shim`, I believe all the `_shim` crates are now gone. - Remove check for `rustc_` and `*san` for `test::Crate::should_run`, these are no longer dependencies in the `test` tree. - Use relative paths in `./x.py test -h -v` output. - Some code cleanup (remove unnecessary `find_compiler_crates`, etc.). - Show suite paths (`src/test/ui/...`) in `./x.py test -h -v` output. - Some doc comments.

bootstrap: read config from $RUST_BOOTSTRAP_CONFIG This PR modifies bootstrap so that `config.toml` is read first from `RUST_BOOTSTRAP_CONFIG`, then `--config` and finally `config.toml` in the current directory. This is a subjective change, intended to improve the ergnomics when using "development shells" for rustc development (for example, using tools such as Nix) which set environment variables to ensure a reproducible environment (these development shells can then be version controlled, e.g. [my rustc shell](https://github.com/davidtwco/veritas/blob/6b74a5c170b6efb2c7b094352932f9158f97eec0/nix/shells/rustc.nix)). By optionally reading `config.toml` from an environment variable, a `config.toml` can be defined in the development shell and a path to it exposed in the `RUST_BOOTSTRAP_CONFIG` environment variable - avoiding the need to manually symlink the contents of this file to `config.toml` in the working directory.

2020-05-13Forbid stage arguments to checkMark Rousskov-0/+14
Users generally expect that check builds are fast, and that's only true in stage 0 (stages beyond that need us to build a compiler, which is slow).

tidy: replace `make check` with `./x.py test` in documentation This PR includes a minor documentation update for tidy. It replaces the `make check` approach with `./x.py test` and describes how to execute the tidy checks (only) with ~~`./x.py test src/tools/tidy`~~ `./x.py test tidy`.

Clarify where the clippy used in `./x.py clippy` is coming from. It uses whatever clippy binary was installed via rustup, cargo-install or otherwise and does NOT use the binary generated by `./x.py build src/tools/clippy`.

2019-03-24Add a way to track Rustfix UI test coveragePhilipp Hansch-0/+15
This came out of the first Rustfix WG meeting. One of the goals is to enable Rustfix tests for all UI tests that trigger lints with `MachineApplicable` suggestions. In order to do that we first want to create a tracking issue that lists all files with missing `// run-rustfix` headers. This PR adds a `--rustfix-coverage` flag to `./x.py` and compiletest to list the files with the missing headers in `/tmp/rustfix_missing_coverage.txt`. From that file we can create the tracking issue and at some point also enforce the `// run-rustfix` flag on UI tests with `MachineApplicable` lints.

Closes #43177.
2018-04-03Refactor to use a dry-run config instead of cfg(test)Mark Simulacrum-1/+3
This ensures that each build will support the testing design of "dry running" builds. It's also checked that a dry run build is equivalent step-wise to a "wet" run build; the graphs we generate when running are directly compared node/node and edge/edge, both for order and contents.
2018-04-03Stop accessing current_dir in bootstrapMark Simulacrum-8/+0
This ensures that the working directory of rustbuild has no effect on it's run; since tests will run with a different cwd this is required for consistent behavior.
2018-03-15Support extra-verbose builds:comex-1/+1
- The bootstrap crate currently passes -v to Cargo if itself invoked with -vv. But Cargo supports -vv (to show build script output), so make bootstrap pass that if itself invoked with -vvv. (More specifically, pass N '-v's to Cargo if invoked with N+1 of them.) - bootstrap.py currently tries to pass on up to two '-v's to cargo when building bootstrap, but incorrectly ('-v' is marked as 'store_true', so argparse stores either False or True, ignoring multiple '-v's). Fix this, allow passing any number of '-v's, and make it consistent with bootstrap's invocation of Cargo (i.e. subtract one from the number of '-v's). - Also improve bootstrap.py's config.toml 'parsing' to support arbitrary verbosity levels, + allow command line to override it.
