}

Everything an architecture states about itself.

Read it through crate::Target::spec, which applies the variant’s refinements; TargetArchitecture::spec is the unrefined form the table states.

Fields

token: &'static str

Canonical spelling, the one Display writes.

spellings: &'static [&'static str]

Further spellings FromStr accepts for this architecture.

targets: &'static [&'static str]

Target strings this architecture contributes to the supported-target list.

pointer_width: PointerWidth

max_int_register_bits: u32

Widest integer one register holds. Not the pointer width: wasm32 has 32-bit pointers and 64-bit integer registers.

endianness: Endianness

va_list: VaListAbi

Size and alignment of this architecture’s C va_list.

stack_alignment_at_call: usize

Alignment the stack pointer holds at a call. 1 means there is no machine stack.

honors_argument_alignment: bool

Whether an argument with 16-byte alignment starts at its own alignment rather than at the next word. AAPCS64 rounds the integer register counter up to even before such an argument; the riscv psABI makes that rule variadic-only and ppc64 does not round for named arguments either.

output_artifact: OutputArtifact

hosted_environment: TargetEnvironment

Environment a hosted target of this architecture means when the target string names none.

environments: &'static [TargetEnvironment]

Environments a target string may name for this architecture, beside TargetEnvironment::Freestanding, which every architecture accepts.

interpreters: LinuxInterpreters

toolchain: ToolchainTriples

msvc_library_arch: Option<&'static str>

Directory name under the Windows SDK Lib tree. None means Windows has no library layout for this architecture, and asking for one is an error rather than a search of the x86_64 directories.

variants: VariantAxis

The sub-architecture axis this architecture has, and its default.

Implementations

impl ArchSpec

pub const fn data_layout(&self) -> TargetDataLayout

pub const fn has_64bit_int_registers(&self) -> bool

pub const fn interpreter( &self, environment: TargetEnvironment, ) -> Option<&'static str>

The ELF interpreter for an environment, or None when there is none.

pub const fn toolchain_triple( &self, environment: TargetEnvironment, ) -> Option<&'static str>

The cross-toolchain triple for an environment.

pub fn accepts_environment(&self, environment: TargetEnvironment) -> bool

Whether a target string may name this environment for this architecture.
