From 6b951b25c35f739ee0a1b5a4615718220830817d Mon Sep 17 00:00:00 2001 From: Eli Friedman Date: Fri, 10 Aug 2012 20:55:20 +0000 Subject: The normal edge of an invoke is not allowed to branch to a block with a landingpad. Enforce it in the verifier, and fix the regression tests to match. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161697 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/Verifier/invoke.ll | 19 +++++++++++++++++-- 1 file changed, 17 insertions(+), 2 deletions(-) (limited to 'test/Verifier') diff --git a/test/Verifier/invoke.ll b/test/Verifier/invoke.ll index 06f40f0..a48f9b6 100644 --- a/test/Verifier/invoke.ll +++ b/test/Verifier/invoke.ll @@ -34,9 +34,12 @@ define void @f1() { entry: ; OK invoke void @llvm.donothing() - to label %cont unwind label %cont + to label %conta unwind label %contb -cont: +conta: + ret void + +contb: %0 = landingpad { i8*, i32 } personality i8* bitcast (i32 (...)* @__gxx_personality_v0 to i8*) filter [0 x i8*] zeroinitializer ret void @@ -63,3 +66,15 @@ entry: %call = call i32 @fn(i8 (i8, i8)* @llvm.expect.i8) ret i32 %call } + +define void @f4() { +entry: + invoke void @llvm.donothing() + to label %cont unwind label %cont + +cont: +; CHECK: Block containing LandingPadInst must be jumped to only by the unwind edge of an invoke. + %0 = landingpad { i8*, i32 } personality i8* bitcast (i32 (...)* @__gxx_personality_v0 to i8*) + filter [0 x i8*] zeroinitializer + ret void +} -- cgit v1.1
