2024-07-25std_detect: Add aarch64/linux/LLVM featuresKajetan Puchalski-9/+190
Add detection for various aarch64 CPU features already supported by LLVM and Linux. This commit adds feature detection for the following features: - FEAT_CSSC - FEAT_ECV - FEAT_FAMINMAX - FEAT_FLAGM2 - FEAT_FP8 - FEAT_FP8DOT2 - FEAT_FP8DOT4 - FEAT_FP8FMA - FEAT_HBC - FEAT_LSE128 - FEAT_LUT - FEAT_MOPS - FEAT_LRCPC3 - FEAT_SVE_B16B16 - FEAT_SVE2p1 - FEAT_WFxT It also adds feature detection for FEAT_FPMR. It is somewhat of a special case because FPMR only exists as a feature in LLVM 18, it has been removed from the LLVM upstream. On that account the intention is for it to be detectable at runtime through stdarch but not have a corresponding compile-time Rust target feature. Linux features: https://github.com/torvalds/linux/blob/master/arch/arm64/include/uapi/asm/hwcap.h LLVM features: llvm-project/llvm/lib/Target/AArch64/AArch64.td
2024-07-14Use LLVM intrinsics for masked load/stores, expand-loads and fp-classsayantn-1240/+479
Also, remove some redundant sse target-features from avx intrinsics
2024-07-14Revert "wasm32: Add `simd128` to enabled features for relaxed intrinsics"daxpedda-20/+20
2024-07-12Some small refactoringssayantn-3417/+13
Use llvm intrinsics for `vfpclassss` and `vfpclasssd` Use `simd_insert` for `x86_polyfill`
2024-07-11wasm32: Add `simd128` to enabled features for relaxed intrinsicsAlex Crichton-20/+20
It looks like LLVM requires that `simd128` is active to use these intrinsics and `relaxed-simd` isn't implicitly enabling them. This is probably something to fix at the LLVM layer as well but for now enable both the `simd128` feature as well as the `relaxed-simd` feature to fix things on our side.

2024-07-06Add detection for SHA512, SM3 and SM4sayantn-2/+38
Cannot cross-verify with `cupid` because they do not have these features yet.
2024-07-06Added a `bf16` typesayantn-21/+52
2024-07-06Implemented some missing functionssayantn-13/+176
These cannot be linked with LLVM because of the lack of `bfloat16` and `i1` types in Rust. So, inline asm was the only way

They should use a platform-specific address management.

2024-06-29Fixed `_mm512_kunpackb`, reduce-max and reduce-minsayantn-28/+32
`_mm512_kunpackb` was implemented wrong, and `simd_reduce_max` uses `maxnum` for comparison, which adheres to IEEE754, but Intel specifically says that they do NOT adhere to IEEE754 for NaNs, which can give wrong results
