clang::OverloadCandidateSet::OperatorRewriteInfo
getRewriteInfo() const

bool isNewCandidate(
    clang::Decl* F,
    clang::OverloadCandidateParamOrder PO =
        OverloadCandidateParamOrder::Normal)

Description

Determine when this overload candidate will be new to the overload set.

Declared at: clang/include/clang/Sema/Overload.h:1091

Parameters

clang::Decl* F
clang::OverloadCandidateParamOrder PO = OverloadCandidateParamOrder::Normal

void setDestAS(clang::LangAS AS)

Declared at: clang/include/clang/Sema/Overload.h:1168

Parameters

clang::LangAS AS

bool shouldDeferDiags(clang::Sema& S,
                      ArrayRef<clang::Expr*> Args,
                      clang::SourceLocation OpLoc)

Declared at: clang/include/clang/Sema/Overload.h:1112

template <typename T>
T* slabAllocate(unsigned int N)

Description

If we have space, allocates from inline storage. Otherwise, allocates from the slab allocator. FIXME: It would probably be nice to have a SmallBumpPtrAllocator instead. FIXME: Now that this only allocates ImplicitConversionSequences, do we want to un-generalize this?

Declared at: clang/include/clang/Sema/Overload.h:1053

Templates

T

Parameters

unsigned int N

~OverloadCandidateSet()
