2019-08-03Require a value for configure --debuginfo-levelJosh Stone-5/+5
In `configure.py`, using the `o` function creates an enable/disable boolean setting, and writes `true` or `false` in `config.toml`. However, rustbuild is expecting to parse a `u32` debuginfo level. We can change to the `v` function to have the options require a value.

2019-06-29Rollup merge of #61755 - Centril:compiletest-force-check, r=petrochenkovMazdak Farrokhzad-0/+24
Add `--pass $mode` to compiletest through `./x.py` Adds a flag `--pass $mode` to compiletest, which is exposed through `./x.py`. When `--pass $mode` is passed, `{check,build,compile,run}-pass` tests will be forced to run under the given `$mode` unless the directive `// ignore-pass` exists in the test file. The modes are explained in https://github.com/rust-lang/rust/pull/61778: - `check` has the same effect as `cargo check` - `build` or `compile` have the same effect as `cargo build` - `run` has the same effect as `cargo run` On my machine, `./x.py -i test src/test/run-pass --stage 1 --pass check` takes 38 seconds whereas it takes 2 min 7 seconds without `--pass check`. cc https://github.com/rust-lang/rust/issues/61712 r? @petrochenkov

rustbuild: detect cxx for all targets Replaces #61544 Fixes #59917 We need CXX to build llvm-libunwind which can be enabled for alltargets. As we needed it for all hosts anyways, just move the detection so that it is ran for all targets (which contains all hosts) instead.

Also removes stage1, stage2 cfgs being passed to rustc to ensure that stage1 and stage2 are only differentiated as a group (i.e., only through not bootstrap).
2019-06-05rustbuild: Include `rustfmt` in deduplicated dependenciesAlex Crichton-0/+1
Currently `rustfmt` is excluded from the "don't build dependencies twice" check but it's currently building dependencies twice! Namely big dependencies like `rustc-ap-syntax` are built once for rustfmt and once for the RLS. This commit includes `rustfmt` in these checks and then fixes the resulting feature mismatches for winapi.

2019-05-30Auto merge of #61212 - alexcrichton:skip-rustc, r=pietroalbinibors-224/+253
ci: Attempt to skip a full rustc compile on dist* Currently when we're preparing cross-compiled compilers it can take quite some time because we have to build the compiler itself three different times. The first is the normal bootstrap, the second is a second build for the build platform, and the third is the actual target architecture compiler. The second compiler was historically built exclusively for procedural macros, and long ago we didn't actually need it. This commit tries out avoiding that second compiled compiler, meaning we only compile rustc for the build platform only once. Some local testing shows that this is promising, but bors is of course the ultimate test!
2019-05-29Rollup merge of #60885 - euclio:strip-synstructure-consts, r=GuillaumeGomezOliver Scherer-1/+1
strip synstructure consts from compiler docs Fixes #60150. Unfortunately this PR depends on the use of the deprecated `--passes` flag in bootstrap to keep the `--strip-hidden` pass while still documenting private items. I've opened #60884 to track stabilization of a new flag that encapsulates this behavior. r? @QuietMisdreavus

2019-05-28rustbuild: Assert extended builds don't dist too muchAlex Crichton-113/+126
This extends a test in the previous commit to assert that we don't build extra rustc compilers even when the "extended" option is set to true. This involved some internal refactoring to have more judicious usage of `compiler_for`, added in the previous commit, as well. Various `dist::*` targets were refactored to be parameterized with a `Compiler` instead of a `stage`/`host`, and then the various parameters within the `Extended` target were tweaked to ensure that we don't ever accidentally ask for a stage2 build compiler when we're distributing something.
2019-05-28rustbuild: Tweak how stage1 compilers are selectedAlex Crichton-98/+98
This commit furthers the previous one to ensure that we don't build an extra stage of the compiler in CI. A test has been added to rustbuild to ensure that this doesn't regress, and then in debugging this test it was hunted down that the `dist::Std` target was the one erroneously pulling in the wrong compiler. The `dist::Std` step was updated to instead account for the "full bootstrap" or not flag, ensuring that the correct compiler for compiling the final standard library was used. This was another use of the `force_use_stage1` function which was in theory supposed to be pretty central, so existing users were all evaluated and a new function, `Builder::compiler_for`, was introduced. All existing users of `force_use_stage1` have been updated to use `compiler_for`, where the semantics of `compiler_for` are similar to that of `compiler` except that it doesn't guarantee the presence of a sysroot for the arguments passed (as they may be modified). Perhaps one day we can unify `compiler` and `compiler_for`, but the usage of `Builder::compiler` is so ubiquitous it would take quite some time to evaluate whether each one needs the sysroot or not, so it's hoped that can be done in parallel.
