2024-09-30Unpin `cc` and upgrade to the latest versionTrevor Gross-1/+1
`cc` was previously pinned because version 1.1.106 dropped support for Visual Studio 12 (2013), and we wanted to decouple that from the rest of the automated updates. As noted in [2], there is no longer anything indicating we support VS2013, so it should be okay to unpin it. `cc` 1.1.22 contains a fix that may help improve the high MSVC CI failure rate [3], so we also have motivation to update to that point.

rustc_llvm: adapt to flattened CLI args in LLVM This changed in llvm/llvm-project@e190d074a0a77c9f8a7d7938a8187a7e2076e290. I decided to stick with more duplication between the ifdef blocks to make the code easier to read for the next two years before we can plausibly drop LLVM 19. `@rustbot` label: +llvm-main try-job: x86_64-msvc

Revert #129749 to fix segfault in LLVM This reverts commit 8c7a7e346be4cdf13e77ab4acbfb5ade819a4e60, reversing changes made to a00bd75b6c5c96d0a35afa2dc07ce3155112d278. Reported in https://github.com/rust-lang/rust/pull/129749#issuecomment-2354417960. `@nikic's` theory is that the LLVM API changed in a way that makes it impossible to use concurrently from multiple threads (https://github.com/llvm/llvm-project/pull/106427#issuecomment-2354783802). I pinged `@krasimirgg` who was fine with reverting. r? `@rust-lang/wg-llvm`

2024-08-12Auto merge of #128371 - andjo403:rangeAttribute, r=nikicbors-0/+12
Add range attribute to scalar function results and arguments as LLVM 19 adds the range attribute this starts to use it for better optimization. hade been interesting to see a perf run with the https://github.com/rust-lang/rust/pull/127513 closes https://github.com/rust-lang/rust/issues/50156 cc https://github.com/rust-lang/rust/issues/49572 shall be fixed but not possible to see as there is asserts that already trigger the optimization.

2024-08-09Enable zstd for debug compression.Kyle Huey-3/+26
Set LLVM_ENABLE_ZSTD alongside LLVM_ENABLE_ZLIB so that --compress-debug-sections=zstd is an option. Use static linking to avoid a new runtime dependency. Add an llvm.libzstd bootstrap option for LLVM with zstd. Set it off by default except for the dist builder. Handle llvm-config --system-libs output that contains static libraries.
2024-07-30Disable MC/DC tests on LLVM 19Krasimir Georgiev-1/+1
Disable the tests and generate an error if MC/DC is used on LLVM 19. The support will be ported separately, as it is substantially different on LLVM 19, and there are no plans to support both versions.

2024-07-12Remove LLVMRustDIBuilderInsertDeclareAtEnd return valueNikita Popov-11/+6
The return value changed from an Instruction to a DbgRecord in LLVM 19. As we don't actually use the result, drop the return value entirely to support both.
2024-07-12Fix incorrect NDEBUG handling in LLVM bindingsNikita Popov-2/+1
We currently compile our LLVM bindings using `-DNDEBUG` if debuginfo for LLVM is disabled. However, `NDEBUG` doesn't have any relation to debuginfo, it controls whether assertions are enabled. Rename the environment variable to `LLVM_ASSERTIONS` and drive it using the `llvm_assertions` option. Also drop the explicit `debug(false)` call, as cc already sets this up using the cargo `DEBUG` environment variable.

2024-07-02Rename the `asm-comments` compiler flag to `verbose-asm`Trevor Gross-2/+2
Since this codegen flag now only controls LLVM-generated comments rather than all assembly comments, make the name more accurate (and also match Clang).

2024-06-27Auto merge of #126907 - glaubitz:sparc-fixes, r=nagisabors-0/+1
Fixes for 32-bit SPARC on Linux This PR fixes a number of issues which previously prevented `rustc` from being built successfully for 32-bit SPARC using the `sparc-unknown-linux-gnu` triplet. In particular, it adds linking against `libatomic` where necessary, uses portable `AtomicU64` for `rustc_data_structures` and rewrites the spec for `sparc_unknown_linux_gnu` to use `TargetOptions` and replaces the previously used `-mv8plus` with the more portable `-mcpu=v9 -m32`. To make `rustc` build successfully, support for 32-bit SPARC needs to be added to the `object` crate as well as the `nix` crate which I will be sending out later as well. r? nagisa
