getObjCXXPersonality()

const EHPersonality & getObjCXXPersonality ( const TargetInfo & target, const LangOptions & langOpts, const CodeGenOptions & cgOpts )

getOrCreateCopyThunk()

cir::FuncOp getOrCreateCopyThunk ( CIRGenFunction & cgf, const VarDecl & catchParam, cir::PointerType paramAddrType, SourceLocation clangLoc )

static

Get or create the catch-init copy thunk for catchParam.

The copy thunk has signature void(T*, T*) (where T is the catch parameter type) and contains the normal aggregate emission of the catch parameter's init expression.

The thunk name is keyed off the catch parameter's canonical type mangled name, so a single translation unit emits at most one thunk per catch type.
