◆ adjustFunctionTypeForInstantiation()

static QualType adjustFunctionTypeForInstantiation ( ASTContext Context,
FunctionDecl D,
TypeSourceInfo TInfo 
)
static

Adjust the given function type for an instantiation of the given declaration, to cope with modifications to the function's type that aren't reflected in the type-source information.

Parameters
DThe declaration we're instantiating.
TInfoThe already-instantiated type.
