New Revision: 267478
URL: http://llvm.org/viewvc/llvm-project?rev=267478&view=rev
Log:
Fix StackFrame::GetVariables(...) function that was broken by 261858 when
lambda functions were added to Block::AppendBlockVariables(). The
Stackframe::GetVariables(...) function should get all variables regardless if
they are in scope.
This wasn't caught by the test suite so I added a test for it.
