Permit building rustdoc without compiler artifacts None
2018-06-02Rustdoc itself no longer requires proc macros to buildMark Simulacrum-2/+1
This avoids a full compiler build in order to build and/or run tests for rustdoc.
2018-05-31Use builder.cargo() for cargo-vendor.Johannes Nixdorf-5/+8
This makes it go through boostrap/bin/rustc.rs, so it will use -crt-static if needed.
2018-05-31builder.cargo(): don't add "--target"/"--release" to cargo installJohannes Nixdorf-5/+10
This is required to use builder.cargo for cargo-vendor.
2018-05-31bootstrap: pass crt-static for the compiler host as wellJohannes Nixdorf-0/+13
2018-05-31bootstrap.py: respect crt-staticJohannes Nixdorf-3/+30
Bootstrap requires serde_derive, which needs proc-macro crate types, so it won't work with crt-static.

2018-05-17Auto merge of #50629 - Mark-Simulacrum:stage-step, r=alexcrichtonbors-8/+7
Switch to bootstrapping from 1.27 It's possible the Float trait could be removed from core, but I couldn't tell whether it was intended to be removed or not. @SimonSapin may be able to comment more here; we can presumably also do that in a follow up PR as this one is already quite large.

2018-05-17Fix rustc binary metadata overwriting librustc metadataMark Simulacrum-1/+1
In #49289, rustc was changed to emit metadata for binaries, which made it so that the librustc.rmeta file created when compiling librustc was overwritten by the rustc-main compilation. This commit renames the rustc-main binary to avoid this problem. https://github.com/rust-lang/cargo/issues/5524 has also been filed to see if Cargo can learn to warn on this situation instead of leaving it for the user to debug.

2018-05-17Rollup merge of #50789 - cuviper:bootstrap-metadata, r=alexcrichtonkennytm-1/+9
Ensure libraries built in stage0 have unique metadata Issue #50786 shows a case with local rebuild where the libraries built by stage0 had the same suffix as stage0's own, and were accidentally loaded by that stage0 rustc when compiling `librustc_trans`. Now we set `__CARGO_DEFAULT_LIB_METADATA` to "bootstrap" during stage0, rather than the release channel like usual, so the library suffix will always be completely distinct from the stage0 compiler.

2018-05-11Auto merge of #50105 - mixi:crt-included, r=alexcrichtonbors-3/+43
Use the correct crt*.o files when linking musl targets. This is supposed to support optionally using the system copy of musl libc instead of the included one if supported. This currently only affects the start files, which is enough to allow building rustc on musl targets. Most of the changes are analogous to crt-static. Excluding the start files is something musl based distributions usually patch into their copy of rustc: - https://github.com/alpinelinux/aports/blob/eb064c8/community/rust/musl-fix-linux_musl_base.patch - https://github.com/voidlinux/void-packages/blob/77400fc/srcpkgs/rust/patches/link-musl-dynamically.patch For third-party distributions that not yet carry those patches it would be nice if it was supported without the need to patch upstream sources. ## Reasons ### What breaks? Some start files were missed when originally writing the logic to swap in musl start files (gcc comes with its own start files, which are suppressed by -nostdlib, but not manually included later on). This caused #36710, which also affects rustc with the internal llvm copy or any other system libraries that need crtbegin/crtend. ### How is it fixed? The system linker already has all the logic to decide which start files to include, so we can just defer to it (except of course if it doesn't target musl). ### Why is it optional? In #40113 it was first tried to remove the start files, which broke compiling musl-targeting static binaries with a glibc-targeting compiler. This is why it eventually landed without removing the start files. Being an option side-steps the issue. ### Why are the start files still installed? This has the nice side-effect, that the produced rust-std-* binaries can still be used by on a glibc-targeting system with a rustc built against glibc. ## Does it work? With the following build script (using [musl-cross-make](https://github.com/richfelker/musl-cross-make)): https://shadowice.org/~mixi/rust-musl/build.sh, I was able to cross-compile a musl-host musl-targeting rustc on a glibc-based system. The resulting binaries are at https://shadowice.org/~mixi/rust-musl/binaries/. This also requires #50103 and #50104 (which are also applied to the branch the build script uses).

2018-05-09ci: Compile LLVM with Clang 6.0.0Alex Crichton-12/+107
Currently on CI we predominately compile LLVM with the default system compiler which means gcc on Linux, some version of Clang on OSX, MSVC on Windows, and gcc on MinGW. This commit switches Linux, OSX, and Windows to all use Clang 6.0.0 to build LLVM (aka the C/C++ compiler as part of the bootstrap). This looks to generate faster code according to #49879 which translates to a faster rustc (as LLVM internally is faster) The major changes here were to the containers that build Linux releases, basically adding a new step that uses the previous gcc 4.8 compiler to compile the next Clang 6.0.0 compiler. Otherwise the OSX and Windows scripts have been updated to download precompiled versions of Clang 6 and configure the build to use them. Note that `cc` was updated here to fix using `clang-cl` with `cc-rs` on MSVC, as well as an update to `sccache` on Windows which was needed to correctly work with `clang-cl`. Finally the MinGW compiler is entirely left out here intentionally as it's currently thought that Clang can't generate C++ code for MinGW and we need to use gcc, but this should be verified eventually.

2018-05-07Auto merge of #50000 - michaelwoerister:cross-lang-lto, r=alexcrichtonbors-7/+43
Add some groundwork for cross-language LTO. Implements part of #49879: - Adds a `-Z cross-lang-lto` flag to rustc - Makes sure that bitcode is embedded in object files if the flag is set. This should already allow for using cross language LTO for staticlibs (where one has to invoke the linker manually anyway). However, `rustc` will not try to enable LTO for its own linker invocations yet. r? @alexcrichton
2018-05-06Auto merge of #50468 - nrc:test-rustfmt, r=alexcrichtonbors-0/+3
Pass a test directory to rustfmt Another attempt to fix the rustfmt tests. `RUSTFMT_TEST_DIR` is consumed by Rustfmt in the latext commit (thus the Rustfmt update) because we need a place to create temp files that won't be read-only. r? @alexcrichton
