Expand description

A compilation error.

When Cranelift fails to compile a function, it will return one of these error codes.

Variants§

§

Verifier(VerifierErrors)

A list of IR verifier errors.

This always represents a bug, either in the code that generated IR for Cranelift, or a bug in Cranelift itself.

§

ImplLimitExceeded

An implementation limit was exceeded.

Cranelift can compile very large and complicated functions, but the implementation has limits that cause compilation to fail when they are exceeded.

§

CodeTooLarge

The code size for the function is too large.

Different target ISAs may impose a limit on the size of a compiled function. If that limit is exceeded, compilation fails.

§

Unsupported(String)

Something is not supported by the code generator. This might be an indication that a feature is used without explicitly enabling it, or that something is temporarily unsupported by a given target backend.

§

RegisterMappingError(RegisterMappingError)

A failure to map Cranelift register representation to a DWARF register representation.

§

Regalloc(CheckerErrors)

Register allocator internal error discovered by the symbolic checker.

§

Pcc(PccError)

Proof-carrying-code validation error.
