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
2023-04-09Auto merge of #109173 - flba-eb:add-i586-qnx70-target, r=compiler-errorsbors-3/+13
Add tier 3 no_std x86 support for QNX Neutrino RTOS, version 7.0 This PR adds the target `i586-pc-nto-qnx700`, which targets QNX Neutrino RTOS version 7.0 on x86 32-bit targets. cc: `@flba-eb` `@gh-tr` This target falls under the umbrella of Tier 3 QNX Neutrino RTOS support documented in `nto-qnx.md` and previously started with #102701.
2023-04-04Auto merge of #109808 - jyn514:debuginfo-options, r=michaelwoeristerbors-3/+5
Extend -Cdebuginfo with new options and named aliases This is a rebase of https://github.com/rust-lang/rust/pull/83947, along with my best guess at what the new options mean. I tried to follow the LLVM source code to get a better idea but ran into quite a lot of trouble (https://rust-lang.zulipchat.com/#narrow/stream/187780-t-compiler.2Fwg-llvm/topic/go-to-definition.20in.20src.2Fllvm-project.3F). The description for the original PR follows below. Note that the changes in this PR have already been through FCP: https://github.com/rust-lang/rust/pull/83947#issuecomment-878384979 Closes https://github.com/rust-lang/rust/pull/109311. Helps with https://github.com/rust-lang/rust/pull/104968. r? `@michaelwoerister` cc `@cuviper` --- The -Cdebuginfo=1 option was never line tables only and can't be due to backwards compatibility issues. This was clarified and an option for emitting line tables only was added. Additionally an option for emitting line info directives only was added, which is needed for some targets, i.e. nvptx. The debug info options should now behave similarly to clang's debug info options. Fix https://github.com/rust-lang/rust/issues/60020 Fix https://github.com/rust-lang/rust/issues/64405

`-Cdebuginfo=1` was never line tables only and can't be due to backwards compatibility issues. This was clarified and an option for line tables only was added. Additionally an option for line info directives only was added, which is well needed for some targets. The debug info options should now behave the same as clang's debug info options.

2023-03-14Rollup merge of #108722 - petrhosek:fuchsia-riscv, r=petrochenkovMatthias Krüger-0/+1
Support for Fuchsia RISC-V target Fuchsia is in the process of implementing the RISC-V support. This change implements the minimal Rust compiler support. The support for building runtime libraries will be implemented in follow up changes once Fuchsia SDK has the RISC-V support.

2023-03-05Rollup merge of #108613 - jyn514:rm-skip-rebuild, r=Mark-SimulacrumMatthias Krüger-1/+0
Remove `llvm.skip-rebuild` option This was added to in 2019 to speed up rebuild times when LLVM was modified. Now that download-ci-llvm exists, I don't think it makes sense to support an unsound option like this that can lead to miscompiles; and the code cleanup is nice too. r? `@Mark-Simulacrum` cc `@varkor` #65612

2023-03-02Auto merge of #106673 - flba-eb:add_qnx_nto_stdlib, r=workingjubileebors-27/+152
Add support for QNX Neutrino to standard library This change: - adds standard library support for QNX Neutrino (7.1). - upgrades `libc` to version `0.2.139` which supports QNX Neutrino `@gh-tr` ⚠️ Backtraces on QNX require https://github.com/rust-lang/backtrace-rs/pull/507 which is not yet merged! (But everything else works without these changes) ⚠️ Tested mainly with a x86_64 virtual machine (see qnx-nto.md) and partially with an aarch64 hardware (some tests fail due to constrained resources).

This updates the test runner to the latest version of the SDK and fixes debugging support for Rust source code.
2023-02-16Remove save-analysis.Nicholas Nethercote-1/+0
Most tests involving save-analysis were removed, but I kept a few where the `-Zsave-analysis` was an add-on to the main thing being tested, rather than the main thing being tested. For `x.py install`, the `rust-analysis` target has been removed. For `x.py dist`, the `rust-analysis` target has been kept in a degenerate form: it just produces a single file `reduced.json` indicating that save-analysis has been removed. This is necessary for rustup to keep working. Closes #43606.

2023-01-09Accept old spelling of Fuchsia target triplesDavid Koloski-0/+2
Because the old spelling is widely used, some projects may need time to migrate their uses to the new triple spelling. The old spelling may eventually be removed altogether.
2023-01-05Add vendor to Fuchsia's target tripleDavid Koloski-50/+50
Historically, Rust's Fuchsia targets have been labeled x86_64-fuchsia and aarch64-fuchsia. However, they should technically contain vendor information. This CL changes Fuchsia's target triples to include the "unknown" vendor since Clang now does normalization and handles all triple spellings. This was previously attempted in #90510, which was closed due to inactivity.
