; 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 -passes=instcombine -disable-output declare ptr @test() define i32 @foo() personality ptr @__gxx_personality_v0 { entry: br i1 true, label %cont, label %call call: ; preds = %entry %P = invoke ptr @test( ) to label %cont unwind label %N ; [#uses=1] cont: ; preds = %call, %entry %P2 = phi ptr [ %P, %call ], [ null, %entry ] ; [#uses=1] %V = load i32, ptr %P2 ; [#uses=1] ret i32 %V N: ; preds = %call %exn = landingpad {ptr, i32} cleanup ret i32 0 } declare i32 @__gxx_personality_v0(...)
