Member Function Documentation

begin()

EHScopeStack::iterator clang::CIRGen::EHScopeStack::begin ( ) const

inline

Returns an iterator pointing to the innermost EH scope.

Definition at line 137 of file CIRGenCleanup.h.

Referenced by popCleanup().

empty()

bool clang::CIRGen::EHScopeStack::empty ( ) const

inline

Determines whether the exception-scopes stack is empty.

Referenced by popCleanup().

popCleanup()

void EHScopeStack::popCleanup

(

)

Pops a cleanup scope off the stack. This is private to CIRGenCleanup.cpp.

Definition at line 92 of file CIRGenCleanup.cpp.

References begin(), cir::MissingFeatures::ehCleanupBranchFixups(), and empty().

pushCleanup()

template<class T , class... As>

void clang::CIRGen::EHScopeStack::pushCleanup ( CleanupKind  kind, As...  a  )

inline

Push a lazily-created cleanup on the stack.

Definition at line 149 of file EHScopeStack.h.

setCGF()

void clang::CIRGen::EHScopeStack::setCGF ( CIRGenFunction *  inCGF )

stable_begin()

stable_iterator clang::CIRGen::EHScopeStack::stable_begin ( ) const

inline

Create a stable reference to the top of the EH stack.

The returned reference is valid until that scope is popped off the stack.

stable_end()

static stable_iterator clang::CIRGen::EHScopeStack::stable_end ( )

inlinestatic

Create a stable reference to the bottom of the EH stack.
