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.
