Jakob Stoklund Olesen 2aad2f6e60 Detect when a value is undefined on an edge to a landing pad. ... Consider this code: int h() { int x; try { x = f(); g(); } catch (...) { return x+1; } return x; } The variable x is undefined on the first edge to the landing pad, but it has the f() return value on the second edge to the landing pad. SplitAnalysis::getLastSplitPoint() would assume that the return value from f() was live into the landing pad when f() throws, which is of course impossible. Detect these cases, and treat them as if the landing pad wasn't there. This allows spill code to be inserted after the function call to f(). <rdar://problem/10664933> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147912 91177308-0d34-0410-b5e6-96231b3b80d8		2012-01-11 02:07:05 +00:00
