2020-12-23Auto merge of #80262 - Mark-Simulacrum:pgo-rustc, r=pietroalbinibors-1/+122
Utilize PGO for rustc linux dist builds This implements support for applying PGO to the rustc compilation step (not standard library or any tooling, including rustdoc). Expanding PGO to more tools is not terribly difficult but will involve more work and greater CI time commitment. For the same reason of avoiding greater implementation time commitment, implementing for platforms outside of x86_64-unknown-linux-gnu is skipped. In practice it should be quite simple to extend over time to more platforms. The initial implementation is intentionally minimal here to avoid too much work investment before we start seeing wins for a subset of Rust users. The choice of workloads to profile here is somewhat arbitrary, but the general rationale was to aim for a small set that largely avoided time regressions on perf.rust-lang.org's full suite of crates. The set chosen is libcore, cargo (and its dependencies), and a few ad-hoc stress tests from perf.rlo. The stress tests are arguably the most controversial, but they benefit those cases (avoiding regressions) and do not really remove wins from other benchmarks. The primary next step after this PR lands is to implement support for PGO in LLVM. It is unclear whether we can afford a full LLVM rebuild in CI, though, so the approach taken there may need to be more staggered. rustc-only PGO seems well affordable on linux at least, giving us up to 20% wall time wins on some crates for 15 minutes of extra CI time (1 hour with this PR, up from 45 minutes). The PGO data is uploaded to allow others to reuse it if attempting to reproduce the CI build or potentially, in the future, on other platforms where an off-by-one strategy is used for dist builds at minimal performance cost. r? `@michaelwoerister` (but tell me if you don't want to / don't feel comfortable approving and we can find others)

2020-12-20Skip `dsymutil` by default for compiler bootstrapJ. Ryan Stinnett-0/+16
`dsymutil` adds time to builds on Apple platforms for no clear benefit, and also makes it more difficult for debuggers to find debug info. The compiler currently defaults to running `dsymutil` to preserve its historical default, but when compiling the compiler itself, we skip it by default since we know it's safe to do so in that case.

2020-12-17bootstrap: update ci-llvm stamp after #80087David Wood-1/+1
Unfortunately, #80087 forgot to update the ci-llvm stamp, so the updated ci-llvm tarball with `llvm-dwp` wasn't downloaded by users. This commit updates the ci-llvm stamp to resolve that problem. Signed-off-by: David Wood <david@davidtw.co>
2020-12-17Rollup merge of #80082 - ehuss:revert-rust-src-vendor, r=Mark-SimulacrumYuki Okushi-45/+2
Revert #78790 - rust-src vendoring This reverts the rust-src vendor changes from #78790. There were a few issues (see #79218, https://github.com/rust-lang/cargo/issues/8962, https://github.com/rust-lang/cargo/issues/8963), that I don't think will get fixed in the next few days before the beta branch. Fixes #79218
2020-12-16bootstrap: include llvm-dwp in CI LLVMDavid Wood-0/+1
This commit includes the `llvm-dwp` tool in the CI LLVM (which rustc developers can download instead of building LLVM locally) - `llvm-dwp` is required by Split DWARF which landed in PR #77117. Signed-off-by: David Wood <david@davidtw.co>
2020-12-16Revert "Auto merge of #78790 - Gankra:rust-src-vendor, r=Mark-Simulacrum"Eric Huss-45/+2
This reverts commit 7afc5172305cdae588a0318ce545749cf4ed947d, reversing changes made to d4ea0b3e46a0303d5802b632e88ba1ba84d9d16f.
2020-12-16compiletest: add split dwarf compare modeDavid Wood-1/+6
This commit adds a Split DWARF compare mode to compiletest so that debuginfo tests are also tested using Split DWARF in split mode (and manually in single mode). Signed-off-by: David Wood <david@davidtw.co>
2020-12-16bootstrap: copy `llvm-dwp` to sysrootDavid Wood-11/+24
`llvm-dwp` is required for linking the DWARF objects into DWARF packages when using Split DWARF, especially given that rustc produces multiple DWARF objects (one for each codegen unit). Signed-off-by: David Wood <david@davidtw.co>

2020-12-13Rollup merge of #79845 - jyn514:python3, r=Mark-SimulacrumYuki Okushi-3/+8
Fix rustup support in default_build_triple for python3 bootstrap completely ignores all errors when detecting a rustup version, so this wasn't noticed before. Fixes the following error: ``` rustup not detected: a bytes-like object is required, not 'str' falling back to auto-detect ``` This also takes the opportunity to only call rustup and other external commands only once during startup. Follow-up to https://github.com/rust-lang/rust/pull/78513.
