2020-08-02Avoid dumping rustc invocations to stdoutMark Rousskov-1/+3
These are quite long, usually, and in most cases not interesting. On smaller terminals they can take up more than a full page of output, hiding the error diagnostics emitted.
2020-07-27rustbuild: refactor how the wrapper deals with exit codesXimin Luo-26/+24
2020-07-27rustbuild: format both Ok/Err separately, since Result doesn't do itXimin Luo-2/+2

2020-07-27rustbuild: rename exec_cmd -> status_code for clarityXimin Luo-3/+3
2020-07-27rustbuild: fix bad usage of UNIX exec() in rustc wrapperXimin Luo-7/+0
exec never returns, it replaces the current process. so anything after it is unreachable. that's not how exec_cmd() is used in the surrounding code

2020-06-29rustbuild: Move compiler-builtins build logic to manifestAlex Crichton-24/+0
This commit moves the compiler-builtins-specific build logic from `src/bootstrap/bin/rustc.rs` into the workspace `Cargo.toml`'s `[profile]` configuration. Now that rust-lang/cargo#7253 is fixed we can ensure that Cargo knows about debug assertions settings, and it can also be configured to specifically disable debug assertions unconditionally for compiler-builtins. This should improve rebuild logic when debug-assertions settings change and also improve build-std integration where Cargo externally now has an avenue to learn how to build compiler-builtins as well.
2020-04-12rustbuild: Remove LLD flavor workaround for MSVCVadim Petrochenkov-5/+0
2020-02-09Auto merge of #68623 - Zoxc:lld, r=Mark-Simulacrumbors-0/+5
Add an option to use LLD to link the compiler on Windows platforms Based on https://github.com/rust-lang/rust/pull/68609. Using LLD is good way to improve compile times on Windows since `link.exe` is quite slow. The time for `x.py build --stage 1 src/libtest` goes from 0:12:00 to 0:08:29. Compile time for `rustc_driver` goes from 226.34s to 18.5s. `rustc_macros` goes from 28.69s to 7.7s. The size of `rustc_driver` is also reduced from 83.3 MB to 78.7 MB. r? @Mark-Simulacrum

2019-09-23Add some FIXME for future Cargo issuesAlex Crichton-0/+6
2019-09-23Move handling of `-Cprefer-dynamic` into `builder.rs`Alex Crichton-7/+0
This logic is *super* old and can be tweaked and moved into `builder.rs`
2019-09-23Move `--cfg bootstrap` out of `rustc.rs`Alex Crichton-15/+0
Instead let's do this via `RUSTFLAGS` in `builder.rs`. Currently requires a submodule update of `stdarch` to fix a problem with previous compilers.
2019-09-23Move handling of `RUSTC_PARALLEL_COMPILER` to `compile.rs`Alex Crichton-4/+0
No longer needs to live in `rustc.rs`
2019-09-23Move handling of `{MUSL,WASI}_ROOT` to `compile.rs`Alex Crichton-19/+1
No longer any need for them to live in `rustc.rs`!
2019-09-23Move debuginfo level handling to `builder.rs`Alex Crichton-4/+0
2019-09-23Remove duplication of `RUSTC_DEBUGINFO_MAP` in rustc.rsAlex Crichton-4/+0

2019-09-23bootstrap: Remove need for `RUSTC_RPATH` variableAlex Crichton-48/+0
2019-09-23bootstrap: Move `RUSTC_CRT_STATIC` to `builder.rs`Alex Crichton-7/+2

2019-09-23bootstrap: Remove usage of `RUSTC_TARGET_LINKER`Alex Crichton-5/+0
Cargo has a native enviroment variable for this.
2019-09-23bootstrap: Move `-Zdual-proc-macros` to `builder.rs`Alex Crichton-6/+0
2019-09-23bootstrap: Move `-Zexternal-macro-backtrace` to builderAlex Crichton-2/+0
No need for this to be in `rustc.rs`
2019-09-23bootstrap: Move `RUSTC_BREAK_ON_ICE` out of shimAlex Crichton-2/+0
This is always set, so let's just always set it elsewhere to reduce the need for our `rustc.rs` shim.
2019-09-23bootstrap: Delete handling of `RUSTC_METADATA_SUFFIX`Alex Crichton-17/+1
This is already handled by `__CARGO_DEFAULT_LIB_METADATA` so there's no need to doubly do it.
2019-09-04Ensure all warnings are emitted even on warnings=warnMark Rousskov-6/+7
2019-08-27rustbuild: allow disabling deny(warnings) for bootstrapMarc-Antoine Perennou-5/+3
When deny-warnings is not specified or set to true, the behaviour is the same as before. When deny-warnings is set to false, warnings are now allowed Fixes #63911 Signed-off-by: Marc-Antoine Perennou <Marc-Antoine@Perennou.com>

2019-08-17Rollup merge of #63642 - eddyb:wrap-it-up, r=rkruppe,Mark-SimulacrumMazdak Farrokhzad-2/+7
Rename overflowing_{add,sub,mul} intrinsics to wrapping_{add,sub,mul}. These confused @Gankra, and then, also me, especially since `overflowing_*` *methods* also exist, but they map to `*_with_overflow` intrinsics! r? @oli-obk / @nikomatsakis cc @Mark-Simulacrum (on the rustbuild workaround)
2019-08-17Rollup merge of #63558 - jgalenson:move-remap, r=alexcrichtonMazdak Farrokhzad-4/+4
Remap paths for proc-macro crates. The remap-debuginfo config option remaps paths in most crates, but it does not apply to proc-macros, so they are still non-reproducible. This patch fixes that. I'm not completely sure if this is the best way to do this, but to get reproducible builds we need librustc_macros to be built with --remap-path-prefix. I was previously modifying Cargo to pass that argument to all child crates, so this seems simpler and more correct. I did not add a test since there do not seem to be any existing tests for RUSTC_DEBUGINFO_MAP. r? @alexcrichton

2019-08-14Disable --cfg bootstrap in libcoreMark Rousskov-1/+5
This is needed to permit us building core_arch which is a submodule dep (so we can't snap it to the new beta compiler).
