Matthias Krüger b9d4ef16c9 Rollup merge of #132552 - taiki-e:sparc-target-feature, r=workingjubilee ... Add v9, v8plus, and leoncasa target feature to sparc and use v8plus in create_object_file This adds the following three unstable target features: - `v9`: SPARC-V9 instructions ([LLVM definition][sparc-v9]) - Relevant to https://github.com/rust-lang/rust/pull/131222#issuecomment-2453310963 - Relevant to https://github.com/rust-lang/rust/pull/132472#discussion_r1832606081 - This is also needed to implement https://github.com/taiki-e/atomic-maybe-uninit/pull/31 (depends on inline assembly support) more robustly. - `v8plus`: SPARC-V8+ ABI ([LLVM definition][sparc-v8plus]) - This is added in LLVM 20. In LLVM 19 and older, it is emulated to work the same way as LLVM in each LLVM version. - See https://github.com/rust-lang/rust/issues/132585#issuecomment-2453926257 for more. - `leoncasa`: CASA instruction[^1] of LEON3 and LEON4 processors ([LLVM definition][sparc-leoncasa], LLVM feature name: `hasleoncasa`) - This is needed to implement https://github.com/taiki-e/atomic-maybe-uninit/pull/31 (depends on inline assembly support) more robustly. [^1]: Atomic CAS instruction [sparc-v9]: f5e4ffaa49/llvm/lib/Target/Sparc/Sparc.td (L37-L39) [sparc-v8plus]: f5e4ffaa49/llvm/lib/Target/Sparc/Sparc.td (L37-L39) [sparc-leoncasa]: https://github.com/llvm/llvm-project/blob/llvmorg-19.1.0/llvm/lib/Target/Sparc/LeonFeatures.td#L32-L37		2024-11-09 10:52:03 +01:00
