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`!

2019-09-23Remove 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).

2019-06-05Utilize cfg(bootstrap) over cfg(stage0)Mark Rousskov-2/+6
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).

2019-05-02Auto merge of #60156 - RalfJung:macos-rand, r=oli-obk,alexcrichtonbors-0/+1
use SecRandomCopyBytes on macOS in Miri This is a hack to fix https://github.com/rust-lang/miri/issues/686: on macOS, rustc will open `/dev/urandom` to initialize a `HashMap`. That's quite hard to emulate properly in Miri without a full-blown implementation of file descriptors. However, Miri needs an implementation of `SecRandomCopyBytes` anyway to support [getrandom](https://crates.io/crates/getrandom), so using it here should work just as well. This will only have an effect when libstd is compiled specifically for Miri, but that will generally be the case when people use `cargo miri`. This is clearly a hack, so I am opening this to start a discussion about whether we are okay with such a hack or not. Cc @oli-obk
