checkUndefinedButUsed - Check for undefined objects with internal linkage or that are inline.

◆ IsCallableWithAppend()

static bool IsCallableWithAppend ( Expr E)
static

Determine whether the given expression can be called by just putting parentheses after it.

Notably, expressions with unary operators can't be because the unary operator will start parsing outside the call.

◆ IsRecordFullyDefined()

static bool IsRecordFullyDefined ( const CXXRecordDecl RD,

static

Returns true, if the given CXXRecordDecl is fully defined in this translation unit, i.e.

all methods are defined or pure virtual and all friends, friend functions and nested classes are fully defined in this translation unit.

Should only be called from ActOnEndOfTranslationUnit so that all definitions are actually read.

◆ noteOverloads()

static void noteOverloads ( Sema S,
const UnresolvedSetImpl Overloads,
const SourceLocation  FinalNoteLoc 
)
static

Give notes for a set of overloads.

A companion to tryExprAsCall. In cases when the name that the programmer wrote was an overloaded function, we may be able to make some guesses about plausible overloads based on their return types; such guesses can be handed off to this method to be emitted as notes.

Parameters
Overloads- The overloads to note.
FinalNoteLoc- If we've suppressed printing some overloads due to -fshow-overloads=best, this is the location to attach to the note about too many candidates. Typically this will be the location of the original ill-formed expression.
