llvm-wrapper: Pass newly added param to DIBuilder::createStaticMemberType() This was added in https://github.com/llvm/llvm-project/pull/72234. DW_TAG_member was the implicit default before. The LLVM change is quite sinister since due to weakly typed ints and default params, this was still successfully compiling against LLVM but was passing the wrong parameters.

rustc_llvm: Link to libkstat on Solaris/SPARC getHostCPUName calls into libkstat but as of LLVM 16.0.6 libLLVMTargetParser is not explicitly linked against libkstat causing builds to fail due to undefined symbols. See also: llvm/llvm-project#64186

2023-10-30Clean up `rustc_*/Cargo.toml`.Nicholas Nethercote-0/+4
- Sort dependencies and features sections. - Add `tidy` markers to the sorted sections so they stay sorted. - Remove empty `[lib`] sections. - Remove "See more keys..." comments. Excluded files: - rustc_codegen_{cranelift,gcc}, because they're external. - rustc_lexer, because it has external use. - stable_mir, because it has external use.

2023-10-25Add support for i586-unknown-netbsd as target.Havard Eidnes-0/+6
This restricts instructions to those offered by Pentium, to support e.g. AMD Geode. There is already an entry for this target in the NetBSD platform support page at src/doc/rustc/src/platform-support/netbsd.md ...so this should forestall its removal. Additional fixes are needed for some vendored modules, this is the changes in the rust compiler core itself.

2023-09-09Rollup merge of #115358 - durin42:compress-debuginfo, r=oli-obkMatthias Krüger-0/+27
debuginfo: add compiler option to allow compressed debuginfo sections LLVM already supports emitting compressed debuginfo. In debuginfo=full builds, the debug section is often a large amount of data, and it typically compresses very well (3x is not unreasonable.) We add a new knob to allow debuginfo to be compressed when the matching LLVM functionality is present. Like clang, if a known-but-disabled compression mechanism is requested, we disable compression and emit uncompressed debuginfo sections. The API is different enough on older LLVMs we just pretend the support is missing on LLVM older than 16.

lto: load bitcode sections by name Upstream change llvm/llvm-project@6b539f5eb8ef1d3a3c87873caa2dbd5147e1adbd changed `isSectionBitcode` works and it now only respects `.llvm.lto` sections instead of also `.llvmbc`, which it says was never intended to be used for LTO. We instead load sections by name, and sniff for raw bitcode by hand. This is an alternative approach to #115136, where we tried the same thing using the `object` crate, but it got too fraught to continue. r? `@nikic` `@rustbot` label: +llvm-main

2023-09-08Rollup merge of #115638 - ldm0:ldm/llvm-args-fix, r=nikicGuillaume Gomez-1/+4
`-Cllvm-args` usability improvement fixes: #26338 fixes: #115564 Two problems were found during playing with `-Cllvm-args` 1. When `llvm.link-shared` is set to `false` in `config.toml`, output of `rustc -C llvm-args='--help-list-hidden'` doesn't contain `--emit-dwarf-unwind` and `--emulated-tls`. When it is set to `true`, `rustc -C llvm-args='--help-list-hidden'` emits `--emit-dwarf-unwind`, but `--emulated-tls` is still missing. 2. Setting `-Cllvm-args=--emit-dwarf-unwind=always` doesn't take any effect, but `-Cllvm-args=-machine-outliner-reruns=3` does work. ### 1 Adding `RegisterCodeGenFlags` to register codegen flags fixed the first problem. `rustc -C llvm-args='--help-list-hidden'` emits full codegen flags including `--emit-dwarf-unwind` and `--emulated-tls`. ### 2 Constructing `TargetOptions` from `InitTargetOptionsFromCodeGenFlags` in `LLVMRustCreateTargetMachine` fixed the second problem. The `LLVMRustSetLLVMOptions` calls `ParseCommandLineOptions` which parses given `llvm-args`. For options like `machine-outliner-reruns`, it just works, since the codegen logic directly consumes the parsing result: [machine-outliner-reruns register](https://github.com/rust-lang/llvm-project/blob/0537f6354cffe546cbf47f6dc9c7f82e49e86cfb/llvm/lib/CodeGen/MachineOutliner.cpp#L114) [machine-outliner-reruns consumption](https://github.com/rust-lang/llvm-project/blob/0537f6354cffe546cbf47f6dc9c7f82e49e86cfb/llvm/lib/CodeGen/MachineOutliner.cpp#L1138) But for flags defined in `TargetOptions` and `MCTargetOptions` to take effect, constructing them with `InitTargetOptionsFromCodeGenFlags` is essential, or the parsing result is just not consumed. Similar patterns can be observed in [lli](https://github.com/rust-lang/llvm-project/blob/0537f6354cffe546cbf47f6dc9c7f82e49e86cfb/llvm/tools/llc/llc.cpp#L494), [llc](https://github.com/rust-lang/llvm-project/blob/0537f6354cffe546cbf47f6dc9c7f82e49e86cfb/llvm/tools/lli/lli.cpp#L517), etc.
2023-09-08Auto merge of #113492 - nebulark:pr_96475, r=petrochenkovbors-1/+38
Add CL and CMD into to pdb debug info Partial fix for https://github.com/rust-lang/rust/issues/96475 The Arg0 and CommandLineArgs of the MCTargetOptions cpp class are not set within https://github.com/rust-lang/rust/blob/bb548f964572f7fe652716f5897d9050a31c936e/compiler/rustc_llvm/llvm-wrapper/PassWrapper.cpp#L378 This causes LLVM to not neither output any compiler path (cl) nor the arguments that were used when invoking it (cmd) in the PDB file. This fix adds the missing information to the target machine so LLVM can use it.
2023-09-08Add missing Debuginfo to PDB debug file on windows.Florian Schmiderer-1/+38

2023-09-02Rollup merge of #114349 - inferiorhumanorgans:dragonfly-link-libz, r=cuviperMatthias Krüger-1/+4
rustc_llvm: Link to `zlib` on dragonfly and solaris On native builds `llvm-config` picks up `zlib` and this gets pased into the rust build tools, but on cross builds `llvm-config` is explicitly ignored as it contains information for the host system and cannot be trusted to be accurate for the target system. Both DragonFly and Solaris contain `zlib` in the base system, so this is both a safe assumption and required for a successful cross build unless `zlib` support is disabled in LLVM. This is more or less in the same vein as rust-lang#75713 and rust-lang#75655.

coverage: Don't convert filename/symbol strings to `CString` for FFI LLVM APIs are usually perfectly happy to accept pointer/length strings, as long as we supply a suitable length value when creating a `StringRef` or `std::string`. This lets us avoid quite a few intermediate `CString` copies during coverage codegen. It also lets us use an `IndexSet<Symbol>` (instead of an `IndexSet<CString>`) when building the deduplicated filename table.
