; Test for a problem afflicting several C++ programs in the testsuite. The ; instcombine pass is trying to get rid of the cast in the invoke instruction, ; inserting a cast of the return value after the PHI instruction, but which is ; used by the PHI instruction. This is bad: because of the semantics of the ; invoke instruction, we really cannot perform this transformation at all at ; least without splitting the critical edge. ; ; RUN: opt < %s -instcombine -disable-output declare i8* @test() define i32 @foo() { entry: br i1 true, label %cont, label %call call: ; preds = %entry %P = invoke i32* bitcast (i8* ()* @test to i32* ()*)( ) to label %cont unwind label %N ; [#uses=1] cont: ; preds = %call, %entry %P2 = phi i32* [ %P, %call ], [ null, %entry ] ; [#uses=1] %V = load i32* %P2 ; [#uses=1] ret i32 %V N: ; preds = %call %exn = landingpad {i8*, i32} personality i32 (...)* @__gxx_personality_v0 cleanup ret i32 0 } declare i32 @__gxx_personality_v0(...)
