Struct GccCodegenBackend 

pub struct GccCodegenBackend {
    compilers: RustcPrivateCompilers,
    targets: Vec<TargetSelection>,
}

Builds the GCC codegen backend (cg_gcc). The cg_gcc backend uses libgccjit, which requires a separate build for each host -> target pair. So if you are on linux-x64 and build for linux-aarch64, you will need at least:

• linux-x64 -> linux-x64 libgccjit (for building host code like proc macros)
• linux-x64 -> linux-aarch64 libgccjit (for the aarch64 target code)

We model this by having a single cg_gcc for a given host target, which contains one libgccjit per (host, target) pair. Note that the host target is taken from self.compilers.target_compiler.host.

Fields

compilers: RustcPrivateCompilers

targets: Vec<TargetSelection>

Implementations

impl GccCodegenBackend

pub fn for_targets( compilers: RustcPrivateCompilers, targets: Vec<TargetSelection>, ) -> Self

Build cg_gcc that will run on host H (compilers.target_compiler.host) and will be able to produce code target pairs (H, T) for all T from targets.

Trait Implementations

impl Clone for GccCodegenBackend

fn clone(&self) -> GccCodegenBackend

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GccCodegenBackend

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for GccCodegenBackend

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for GccCodegenBackend

fn eq(&self, other: &GccCodegenBackend) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Step for GccCodegenBackend

const IS_HOST: bool = true

If this value is true, then the values of run.target passed to the make_run function of this Step will be determined based on the --host flag. If this value is false, then they will be determined based on the --target flag.

type Output = GccCodegenBackendOutput

Result type of Step::run.

fn should_run(run: ShouldRun<'_>) -> ShouldRun<'_>

Called to allow steps to register the command-line paths that should cause them to run.

fn make_run(run: RunConfig<'_>)

Called directly by the bootstrap Step handler when not triggered indirectly by other Steps using Builder::ensure. For example, ./x.py test bootstrap runs this for test::Bootstrap. Similarly, ./x.py test runs it for every step that is listed by the describe macro in Builder::get_step_descriptions.

fn run(self, builder: &Builder<'_>) -> Self::Output

Primary function to implement Step logic.

fn metadata(&self) -> Option<StepMetadata>

Returns metadata of the step, for tests

fn is_default_step(_builder: &Builder<'_>) -> bool

Should this step run when the user invokes bootstrap with a subcommand but no paths/aliases?

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
