class Sema::SemaDiagnosticBuilder

Declaration

class Sema::SemaDiagnosticBuilder { /* full declaration omitted */ };

Description

A generic diagnostic builder for errors which may or may not be deferred. In CUDA, there exist constructs (e.g. variable-length arrays, try/catch) which are not allowed to appear inside __device__ functions and are allowed to appear in __host__ __device__ functions only if the host+device function is never codegen'ed. To handle this, we use the notion of "deferred diagnostics", where we attach a diagnostic to a FunctionDecl that's emitted iff it's codegen'ed. This class lets you emit either a regular diagnostic, a deferred diagnostic, or no diagnostic at all, according to an argument you pass to its constructor, thus simplifying the process of creating these "maybe deferred" diagnostics.

Description

Convertible to bool: True if we immediately emitted an error, false if we didn't emit an error or we created a deferred error. Example usage: if (SemaDiagnosticBuilder(...) < < foo < < bar) return ExprError(); But see CUDADiagIfDeviceCode() and CUDADiagIfHostCode() -- you probably want to use these instead of creating a SemaDiagnosticBuilder yourself.
