Struct rustc_back::target::TargetUnstable

pub struct Target {
    pub data_layout: String,
    pub llvm_target: String,
    pub target_endian: String,
    pub target_pointer_width: String,
    pub target_os: String,
    pub arch: String,
    pub options: TargetOptions,
}

Everything rustc knows about how to compile for a specific target.

Every field here must be specified, and has no default value.

Fields

data_layout	Data layout to pass to LLVM.
llvm_target	Target triple to pass to LLVM.
target_endian	String to use as the target_endian cfg variable.
target_pointer_width	String to use as the target_pointer_width cfg variable.
target_os	OS name to use for conditional compilation.
arch	Architecture to use for ABI considerations. Valid options: "x86", "x86_64", "arm", "aarch64", "mips", and "powerpc". "mips" includes "mipsel".
options	Optional settings with defaults.

Methods

impl Target

fn adjust_abi(&self, abi: Abi) -> Abi

Given a function ABI, turn "System" into the correct ABI for this target.

fn from_json(obj: Json) -> Target

Load a target descriptor from a JSON object.

fn search(target: &str) -> Result<Target, String>

Search RUST_TARGET_PATH for a JSON file specifying the given target triple. Note that it could also just be a bare filename already, so also check for that. If one of the hardcoded targets we know about, just return it directly.

The error string could come from any of the APIs called, including filesystem access and JSON decoding.
