Ensure it shows up in the same places it did before so tools can find it at runtime.
2019-12-11rustc: Link LLVM directly into rustc againAlex Crichton-1/+1
This commit builds on #65501 continue to simplify the build system and compiler now that we no longer have multiple LLVM backends to ship by default. Here this switches the compiler back to what it once was long long ago, which is linking LLVM directly to the compiler rather than dynamically loading it at runtime. The `codegen-backends` directory of the sysroot no longer exists and all relevant support in the build system is removed. Note that `rustc` still supports a dynamically loaded codegen backend as it did previously, it just no longer supports dynamically loaded codegen backends in its own sysroot. Additionally as part of this the `librustc_codegen_llvm` crate now once again explicitly depends on all of its crates instead of implicitly loading them through the sysroot. This involved filling out its `Cargo.toml` and deleting all the now-unnecessary `extern crate` annotations in the header of the crate. (this in turn required adding a number of imports for names of macros too). The end results of this change are: * Rustbuild's build process for the compiler as all the "oh don't forget the codegen backend" checks can be easily removed. * Building `rustc_codegen_llvm` is much simpler since it's simply another compiler crate. * Managing the dependencies of `rustc_codegen_llvm` is much simpler since it's "just another `Cargo.toml` to edit" * The build process should be a smidge faster because there's more parallelism in the main rustc build step rather than splitting `librustc_codegen_llvm` out to its own step. * The compiler is expected to be slightly faster by default because the codegen backend does not need to be dynamically loaded. * Disabling LLVM as part of rustbuild is still supported, supporting multiple codegen backends is still supported, and dynamic loading of a codegen backend is still supported.
2019-09-23Allow adding `RUSTFLAGS` after `Builder::cargo`Alex Crichton-3/+3
This commit changes the return type of `Builder::cargo` to return a builder that allows dynamically adding more `RUSTFLAGS` values after-the-fact. While not used yet, this will later be used to delete more of `rustc.rs`
2019-09-19rustbuild: Copy crate doc files fewer timesAlex Crichton-1/+1
Previously when building documentation for the standard library we'd copy all the files 5 times, and these files include libcore/libstd docs which are huge! This commit instead only copies the files after rustdoc has been run for each crate, reducing the number of redundant copies we're making.

2019-08-23bootstrap: Merge the libtest build step with libstdAlex Crichton-127/+1
Since its inception rustbuild has always worked in three stages: one for libstd, one for libtest, and one for rustc. These three stages were architected around crates.io dependencies, where rustc wants to depend on crates.io crates but said crates don't explicitly depend on libstd, requiring a sysroot assembly step in the middle. This same logic was applied for libtest where libtest wants to depend on crates.io crates (`getopts`) but `getopts` didn't say that it depended on std, so it needed `std` built ahead of time. Lots of time has passed since the inception of rustbuild, however, and we've since gotten to the point where even `std` itself is depending on crates.io crates (albeit with some wonky configuration). This commit applies the same logic to the two dependencies that the `test` crate pulls in from crates.io, `getopts` and `unicode-width`. Over the many years since rustbuild's inception `unicode-width` was the only dependency picked up by the `test` crate, so the extra configuration necessary to get crates building in this crate graph is unlikely to be too much of a burden on developers. After this patch it means that there are now only two build phasese of rustbuild, one for libstd and one for rustc. The libtest/libproc_macro build phase is all lumped into one now with `std`. This was originally motivated by rust-lang/cargo#7216 where Cargo was having to deal with synthesizing dependency edges but this commit makes them explicit in this repository.
2019-08-20Remove serialization of diagnostics to filesMark Rousskov-2/+1
This is no longer used by the index generator and was always an unstable compiler detail, so strip it out. This also leaves in RUSTC_ERROR_METADATA_DST since the stage0 compiler still needs it to be set.

2019-05-30Auto merge of #61212 - alexcrichton:skip-rustc, r=pietroalbinibors-30/+5
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!
2019-05-28rustbuild: Tweak how stage1 compilers are selectedAlex Crichton-30/+5
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.

2018-12-07use top level `fs` functions where appropriateAndy Russell-8/+6
This commit replaces many usages of `File::open` and reading or writing with `fs::read_to_string`, `fs::read` and `fs::write`. This reduces code complexity, and will improve performance for most reads, since the functions allocate the buffer to be the size of the file. I believe that this commit will not impact behavior in any way, so some matches will check the error kind in case the file was not valid UTF-8. Some of these cases may not actually care about the error.
