Steps: - [x] Use LLVM 15 as a bootstrap compiler and use it to build BOLT - [x] Compile LLVM with support for relocations (`-DCMAKE_SHARED_LINKER_FLAGS="-Wl,-q"`) - [x] Gather profile data using instrumented LLVM - [x] Apply profile to LLVM that has already been PGOfied - [x] Run with BOLT profiling on more benchmarks - [x] Decide on the order of optimization (PGO -> BOLT?) - [x] Decide how we should get `bolt` (currently we use the host `bolt`) - [x] Clean up The latest perf results can be found [here](https://github.com/rust-lang/rust/pull/94381#issuecomment-1258269440). The current CI build time with BOLT applied is around 1h 55 minutes. 2022-10-09T09:31:09+00:00 Jakub Beránek berykubik@gmail.com 2022-10-02T07:44:04+00:00 urn:sha1:cc475f5ef2988e9db2e3ce07bd4abd4d4975f3e7 2022-10-07T22:27:48+00:00 Josh Stone jistone@redhat.com 2022-10-07T22:12:27+00:00 urn:sha1:a027474ea6b424aa4101edc9d15d8ebe677783e9 2022-10-07T18:24:02+00:00 Josh Stone jistone@redhat.com 2022-10-07T18:24:02+00:00 urn:sha1:128344196ba5d7da8185e498706996a135849b5f 2022-10-02T20:55:17+00:00 bors bors@rust-lang.org 2022-10-02T20:55:17+00:00 urn:sha1:de692f1fae957fcfb0efb46db044a61261169963 fix: use git-commit-info for version information Fixes #33286. Fixes #86587. This PR changes the current `git-commit-hash` file that `./x.py` dist puts in the `rustc-{version}-src.tar.{x,g}z` to contain the hash, the short hash, and the commit date from which the tarball was created, assuming git was available when it was. It uses this for reading the version so that rustc has all the appropriate metadata. # Testing Testing this is kind of a pain. I did it with something like ```sh ./x.py dist # ensure that `ignore-git` is `false` in config.toml cp ./build/dist/rustc-1.65.0-dev-src.tar.gz ../rustc-1.65.0-dev-src.tar.gz cd .. && tar -xzf rustc-1.65.0-dev-src && cd rustc-1.65.0-dev-src ./x.py build ``` Then, the output of `rustc -vV` with the stage1 compiler should have the `commit-hash` and `commit-date` fields filled, rather than be `unknown`. To be completely sure, you can use `rustc --sysroot` with the stdlib that the original `./x.py dist` made, which will require that the metadata matches. 2022-10-01T21:46:18+00:00 dawnofmidnight dawnofmidnight@duck.com 2022-08-24T16:36:08+00:00 urn:sha1:fdb39551ddfb431ee1edb61731a68927a06649f7 This PR adds support for fetching version information from the `git-commit-info` file when building the compiler from a source tarball. 2022-09-16T20:08:44+00:00 Chris Wailes chriswailes@google.com 2022-09-13T23:06:07+00:00 urn:sha1:999502978612be1379240f792614f8580e49d123 This commit removes an allow-list for the dynamic linking of the LLVM tools and instead relies on the builder's linking preference only. 2022-09-01T05:39:58+00:00 bors bors@rust-lang.org 2022-09-01T05:39:58+00:00 urn:sha1:b32223fec10743af93913c41ec60645d741b0cb6 Fix a bunch of typo This PR will fix some typos detected by [typos].
