2024-11-03Auto merge of #132514 - Zalathar:print-target-cpus, r=jieyouxubors-41/+9
Port most of `--print=target-cpus` to Rust The logic and formatting needed by `--print=target-cpus` has historically been carried out in C++ code. Originally it used `printf` to write directly to the console, but later it switched over to writing to a `std::ostringstream` and then passing its buffer to a callback function pointer. This PR replaces that C++ code with a very simple function that writes a list of CPU names to a `&RustString`, with the rest of the logic and formatting being handled by ordinary safe Rust code.

2024-10-30Rollup merge of #132342 - Zalathar:operand-bundle, r=workingjubileeMatthias Krüger-64/+14
cg_llvm: Clean up FFI calls for operand bundles All of these FFI functions have equivalents in the stable LLVM-C API, though `LLVMBuildCallBr` requires a temporary polyfill on LLVM 18. This PR also creates a clear split between `OperandBundleOwned` and `OperandBundle`, and updates the internals of the owner to be a little less terrifying.

2024-10-29Rollup merge of #132319 - Zalathar:add-module-flag, r=jieyouxuMatthias Krüger-12/+50
cg_llvm: Clean up FFI calls for setting module flags This is a combination of several inter-related changes to how module flags are set: - Remove some unnecessary code for setting an `"LTOPostLink"` flag, which has been obsolete since LLVM 17. - Define our own enum instead of relying on enum values defined by LLVM's unstable C++ API. - Use safe wrapper functions to set module flags, instead of direct `unsafe` calls. - Consistently pass pointer/length strings instead of C strings. - Remove or shrink some `unsafe` blocks.

2024-10-29Don't set unnecessary module flag "LTOPostLink"Zalathar-5/+0
This module flag was an internal detail of LLVM's optimization passes, and all code involving it was removed in LLVM 17. <https://github.com/llvm/llvm-project/commit/200cc952a28a73687ba24d5334415df6332f2d5b>

2024-10-24Rollup merge of #131956 - Zalathar:llvm-counters, r=compiler-errors,SwatinemStuart Cook-91/+91
coverage: Pass coverage mappings to LLVM as separate structs Instead of trying to cram *N* different kinds of coverage mapping data into a single list for FFI, pass *N* different lists of simpler structs. This avoids the need to fill unused fields with dummy values, and avoids the need to tag structs with their underlying kind. It also lets us call the dedicated LLVM constructors for each different mapping type, instead of having to go through the complex general-purpose constructor. Even though this adds multiple new structs to the FFI surface area, the resulting C++ code is simpler and shorter. --- I've structured this mostly as a single atomic patch, rather than a series of incremental changes, because that avoids the need to make fiddly fixes to code that is about to be deleted anyway.

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`
