From f1b0a345d31ba952e333cf8cc5b039b8ab82857a Mon Sep 17 00:00:00 2001 From: Bob Wilson Date: Mon, 15 Feb 2010 21:56:40 +0000 Subject: [PATCH] Last week we were generating code with duplicate induction variables in this test, but the problem seems to have gone away today. Add a check to make sure it doesn't come back. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96277 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/Thumb2/2010-02-11-phi-cycle.ll | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/test/CodeGen/Thumb2/2010-02-11-phi-cycle.ll b/test/CodeGen/Thumb2/2010-02-11-phi-cycle.ll index 0f23ee75683..363f5719d17 100644 --- a/test/CodeGen/Thumb2/2010-02-11-phi-cycle.ll +++ b/test/CodeGen/Thumb2/2010-02-11-phi-cycle.ll @@ -58,6 +58,10 @@ bb1: ; preds = %bb br label %bb2 bb2: ; preds = %bb1, %bb +; also check for duplicate induction variables (radar 7645034) +; CHECK: subs r{{.*}}, #1 +; CHECK-NOT: subs r{{.*}}, #1 +; CHECK: pop %u.0 = phi i64 [ %ins, %bb1 ], [ %u.17, %bb ] ; [#uses=2] %indvar.next = add i32 %indvar, 1 ; [#uses=2] %exitcond = icmp eq i32 %indvar.next, %tmp ; [#uses=1]
