2024-07-29Reformat `use` declarations.Nicholas Nethercote-39/+72
The previous commit updated `rustfmt.toml` appropriately. This commit is the outcome of running `x fmt --all` with the new formatting options.
2024-06-22compiler: Fix arm32 asm issues by hierarchically sorting reg classesJubilee Young-40/+40
2024-06-22Rollup merge of #126555 - beetrees:f16-inline-asm-arm, r=AmanieuGuillaume Gomez-5/+7
Add `f16` inline ASM support for 32-bit ARM Adds `f16` inline ASM support for 32-bit ARM.

2024-04-11Rollup merge of #123740 - veera-sivarajan:reduce-size-of-modifierinfo, ↵Matthias Krüger-3/+3
r=petrochenkov Reduce Size of `ModifierInfo` I added `ModifierInfo` in #121940 and had used a `u64` for the `size` field even though the largest value it holds is `512`. This PR changes the type of the `size` field to `u16`.

2022-04-19asm: Add a kreg0 register class on x86 which includes k0Amanieu d'Antras-8/+9
Previously we only exposed a kreg register class which excludes the k0 register since it can't be used in many instructions. However k0 is a valid register and we need to have a way of marking it as clobbered for clobber_abi. Fixes #94977
2022-03-22Fold aarch64 feature +fp into +neonJubilee Young-1/+1
Arm's FEAT_FP and Feat_AdvSIMD describe the same thing on AArch64: The Neon unit, which handles both floating point and SIMD instructions. Moreover, a configuration for AArch64 must include both or neither. Arm says "entirely proprietary" toolchains may omit floating point: https://developer.arm.com/documentation/102374/0101/Data-processing---floating-point In the Programmer's Guide for Armv8-A, Arm says AArch64 can have both FP and Neon or neither in custom implementations: https://developer.arm.com/documentation/den0024/a/AArch64-Floating-point-and-NEON In "Bare metal boot code for Armv8-A", enabling Neon and FP is just disabling the same trap flag: https://developer.arm.com/documentation/dai0527/a In an unlikely future where "Neon and FP" become unrelated, we can add "[+-]fp" as its own feature flag. Until then, we can simplify programming with Rust on AArch64 by folding both into "[+-]neon", which is valid as it supersets both. "[+-]neon" is retained for niche uses such as firmware, kernels, "I just hate floats", and so on.
2022-02-24ARM: Only allow using d16-d31 with asm! when supported by the targetAmanieu d'Antras-1/+4
Support can be determined by checking for the "d32" LLVM feature.
2022-02-21Add testsAmanieu d'Antras-2/+2
2022-02-21Take CodegenFnAttrs into account when validating asm! register operandsAmanieu d'Antras-120/+94
Checking of asm! register operands now properly takes function attributes such as #[target_feature] and #[instruction_set] into account.
2022-02-21On ARM, use relocation_model to detect whether r9 should be reservedAmanieu d'Antras-44/+58
The previous approach of checking for the reserve-r9 target feature didn't actually work because LLVM only sets this feature very late when initializing the per-function subtarget.
2022-02-21Simplify gating of BPF w registers behind the alu32 target featureAmanieu d'Antras-26/+12
This is already handled by supported_types().
2022-02-18asm: Allow the use of r8-r14 as clobbers on Thumb1Amanieu d'Antras-41/+91
Previously these were entirely disallowed, except for r11 which was allowed by accident.

Also restricts r8-r14 from being used on Thumb1 targets as per #90736.
