Enum CompileError 

#[non_exhaustive]
pub enum CompileError {
    Invalid(ValidationError),
    Select {
        function: String,
        error: IselError,
    },
    Allocate {
        function: String,
        error: RegAllocError,
    },
    Emit {
        function: Option<String>,
        error: EmitError,
    },
}

Why a module could not be compiled.

Examples

use backend_lang::{CompileError, Options};
use ir_lang::{Linkage, Module, Signature, Type};

let mut m = Module::new("m");
let f = m.declare_function("f", &Signature::new(&[], &[Type::F32]), Linkage::Export)?;
let mut b = m.build(f)?;
let x = b.f32const(1.0)?;
b.ret(&[x])?;
let err = backend_lang::compile(&m, &Options::sysv()).unwrap_err();
assert!(matches!(err, CompileError::Select { .. }));

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Invalid(ValidationError)

The module does not validate.

Select

Instruction selection failed for a function.

Fields

function: String

The function.

error: IselError

Why.

Allocate

Register allocation failed for a function.

Fields

function: String

The function.

error: RegAllocError

Why.

Emit

Emission failed (for a function, if one is named).

Fields

function: Option<String>

The function, if the failure belongs to one.

error: EmitError

Why.

Trait Implementations

impl Clone for CompileError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompileError

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

Formats the value using the given formatter.

impl Display for CompileError

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

Formats the value using the given formatter.

impl Eq for CompileError

impl Error for CompileError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for CompileError

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

Equality operator ==.

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

Inequality operator !=.
