Expand description

Error information for when the program we executed turned out not to actually be a valid program. This cannot happen in stand-alone Miri, but it can happen during CTFE/ConstProp where we work on generic code or execution does not have all information available.

Variants§

§

TooGeneric

Resolution can fail if we are in a too generic context.

§

AlreadyReported(ReportedErrorInfo)

Abort in case errors are already reported.

§

Layout(LayoutError<'tcx>)

An error occurred during layout computation.

§

FnAbiAdjustForForeignAbi(AdjustForForeignAbiError)

An error occurred during FnAbi computation: the passed –target lacks FFI support (which unfortunately typeck does not reject). Not using FnAbiError as that contains a nested LayoutError.

§

ConstPropNonsense

We are runnning into a nonsense situation due to ConstProp violating our invariants.
