Expand description

An error or inconsistency discovered when checking proof-carrying code.

Variants§

§

Overflow

An operation wraps around, invalidating the stated value range.

§

MissingFact

An input to an operator that produces a fact-annotated value does not have a fact describing it, and one is needed.

§

UnsupportedFact

A derivation of an output fact is unsupported (incorrect or not derivable).

§

UnsupportedBlockparam

A block parameter claims a fact that one of its predecessors does not support.

§

OutOfBounds

A memory access is out of bounds.

§

UnimplementedBackend

Proof-carrying-code checking is not implemented for a particular compiler backend.

§

UnimplementedInst

Proof-carrying-code checking is not implemented for a particular instruction that instruction-selection chose. This is an internal compiler error.

§

InvalidFieldOffset

Access to an invalid or undefined field offset in a struct.

§

BadFieldType

Access to a field via the wrong type.

§

WriteToReadOnlyField

Store to a read-only field.

§

InvalidStoredFact

Store of data to a field with a fact that does not subsume the field’s fact.
