Strip unexpected debuginfo from `libLLVM.so` and `librustc_driver.so` when not requesting any debuginfo As seen in #114175 and in [this zulip discussion](https://rust-lang.zulipchat.com/#narrow/stream/247081-t-compiler.2Fperformance/topic/Artifact.20sizes/near/379302655), there's still some small amount of debuginfo in LLVM's shared library on linux, even when not requesting it (nightly CI), coming from `libstdc++`. ``` $ readelf --debug-dump=info ~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/libLLVM-16-rust-1.73.0-nightly.so | grep DW_TAG_compile_unit -A5 | grep DW_AT_comp_dir | cut -d ":" -f 2- | counts 101 counts ( 1) 39 (38.6%, 38.6%): (indirect string, offset: 0x7): /tmp/gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/libsupc++ ( 2) 38 (37.6%, 76.2%): (indirect string, offset: 0x43fb2): /tmp/gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/src/c++11 ( 3) 23 (22.8%, 99.0%): (indirect string, offset: 0x18ed8): /tmp/gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/src/c++98 ( 4) 1 ( 1.0%,100.0%): (indirect string, offset: 0x53f04): /tmp/gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/src ``` Similarly, here's `librustc_driver.so` when not requesting debuginfo from either rustc or the tools (nightly CI), coming e.g. from our LLVM wrapper: ``` $ readelf --debug-dump=info ~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/librustc_driver-e534b3a316089f5f.so | grep DW_TAG_compile_unit -A5 | grep DW_AT_comp_dir | cut -d ":" -f 2- | counts 116 counts ( 1) 34 (29.3%, 29.3%): (indirect string, offset: 0x3c11): /tmp/gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/libsupc++ ( 2) 32 (27.6%, 56.9%): (indirect string, offset: 0x9753c): /tmp/gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/src/c++11 ( 3) 25 (21.6%, 78.4%): (indirect string, offset: 0x393bd): /tmp/gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/src/c++98 ( 4) 23 (19.8%, 98.3%): (indirect string, offset: 0x33ed3): /cargo/registry/src/index.crates.io-6f17d22bba15001f/compiler_builtins-0.1.98 ( 5) 1 ( 0.9%, 99.1%): (indirect string, offset: 0xaffff): /rustc/0d95f9132909ae7c5f2456748d0ffd1c3ba4a8e8 ( 6) 1 ( 0.9%,100.0%): (indirect string, offset: 0xb604a): /tmp/gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/src ``` To reduce the size of distributed artifacts, this PR strips debuginfo from the LLVM and `rustc_driver` shared libraries, when: - no debuginfo is requested when building LLVM: `link-shared` is true, `optimize` is true and `release-debuginfo` is false - no debuginfo is requested when building the rustc driver: - `debuginfo-level-rustc` and `debuginfo-level-tools` are off. - when building with a stage != 0 compiler: since this is about the distributed artifacts, there's no need to do this at other stages. - for both: on a x64 linux host and target where `strip -g` is available and fixes the issue (I don't know how to strip debuginfo from a `.dylib` on mac). The LLVM BOLTed .so, and `librustc_driver.so` are big there, and this will help a little. Other targets/hosts can be added in the future if we want to. #114175 did the same thing unconditionally in `opt-dist`, prior to BOLTing LLVM. But this should only be used in conjunction with the other config options mentioned above, and which `opt-dist` doesn't know about. Therefore, it makes more sense as in bootstrap when building LLVM and rustc when applicable and no debuginfo is requested. This shouldn't interact badly with CI caching builds and artifacts, right? --- From the other PR, `libLLVM-16-rust-1.73.0-nightly.so` prior to #114141: - master: 173.13 MiB - stripped debuginfo: 165.12 MiB (-8 MiB, -4.6%) `libLLVM-16-rust-1.73.0-nightly.so` after #114141: - master: 121.13 MiB - stripped debuginfo: 113.12 MiB (still -8 MiB, -6.6%) `librustc_driver.so`: - master: 118.58 MiB - stripped debuginfo: 106.46 MiB (-12 MiB, -10.2%) (Results are also available in this most recent [perf run's artifact sizes](https://perf.rust-lang.org/compare.html?start=b321edd1b2d4bd00c7b4611e8f20a03ee7b77023&end=810ab570d5d27facb91806e5d9847815d9dac22a&stat=instructions%3Au&tab=artifact-size))

bootstrap: use git merge-base for LLVM CI download logic Fixes https://github.com/rust-lang/rust/issues/101907 I tested this with a local branch that has extra merge commits due to Miri, and it worked fine there. But I am sure there are tons of other situations I did not think of... r? `@jyn514`

2023-07-24bootstrap: Define CMake platform if DragonFly.Alex Zepeda-0/+7
CMAKE_SYSTEM_NAME is defined on a cross build if the target is recognized. Without this explicit definition cmake will assume that we're building for the host platform which can bring in unwanted compiler and linker flags. Also, add a warning on cross builds with unknown target to aid in cross builds for future platforms.

Add x86_64-unknown-linux-ohos target This complements the existing `aarch64-unknown-linux-ohos` and `armv7-unknown-linux-ohos` targets. This should be covered by the existing MCP (https://github.com/rust-lang/compiler-team/issues/568), but I can also create a new MCP if that is preferred.

2023-06-03rust-lld: add rpath to the root LLVM shared libRémy Rakic-0/+24
rust-lld is not located in the same directory as the other binaries that point to ../lib, but in a deeper directory in lib. So we need to point a few layers up for rust-lld to find the LLVM shared library without rustup's LD_LIBRARY_PATH overrides.
2023-05-26Add SafeStack support to rustcWesley Wiser-1/+1
Adds support for LLVM [SafeStack] which provides backward edge control flow protection by separating the stack into two parts: data which is only accessed in provable safe ways is allocated on the normal stack (the "safe stack") and all other data is placed in a separate allocation (the "unsafe stack"). SafeStack support is enabled by passing `-Zsanitizer=safestack`. [SafeStack]: https://clang.llvm.org/docs/SafeStack.html

Initial support for loongarch64-unknown-linux-gnu Hi, We hope to add a new port in rust for LoongArch. LoongArch intro LoongArch is a RISC style ISA which is independently designed by Loongson Technology in China. It is divided into two versions, the 32-bit version (LA32) and the 64-bit version (LA64). LA64 applications have application-level backward binary compatibility with LA32 applications. LoongArch is composed of a basic part (Loongson Base) and an expanded part. The expansion part includes Loongson Binary Translation (LBT), Loongson VirtualiZation (LVZ), Loongson SIMD EXtension (LSX) and Loongson Advanced SIMD EXtension(LASX). Currently the LA464 processor core supports LoongArch ISA and the Loongson 3A5000 processor integrates 4 64-bit LA464 cores. LA464 is a four-issue 64-bit high-performance processor core. It can be used as a single core for high-end embedded and desktop applications, or as a basic processor core to form an on-chip multi-core system for server and high-performance machine applications. Documentations: ISA: https://loongson.github.io/LoongArch-Documentation/LoongArch-Vol1-EN.html ABI: https://loongson.github.io/LoongArch-Documentation/LoongArch-ELF-ABI-EN.html More docs can be found at: https://loongson.github.io/LoongArch-Documentation/README-EN.html Since last year, we have locally adapted two versions of rust, rust1.41 and rust1.57, and completed the test locally. I'm not sure if I'm submitting all the patches at once, so I split up the patches and here's one of the commits
