From 1ff06b231fb84080398518b9fb49f13b25d2259c Mon Sep 17 00:00:00 2001 From: Zhou Sheng Date: Fri, 30 Jan 2009 08:59:51 +0000 Subject: This is case is to uncover the bug in IntrinsicLowering.cpp, the LowerPartSet(). It didn't handle the situation correctly when the low, high argument values are in reverse order (low > high) with 'Val' type is i32 (a corner case). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63386 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/ExecutionEngine/2009-01-29-PartSet.ll | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 test/ExecutionEngine/2009-01-29-PartSet.ll (limited to 'test/ExecutionEngine') diff --git a/test/ExecutionEngine/2009-01-29-PartSet.ll b/test/ExecutionEngine/2009-01-29-PartSet.ll new file mode 100644 index 0000000000..ae766876fc --- /dev/null +++ b/test/ExecutionEngine/2009-01-29-PartSet.ll @@ -0,0 +1,17 @@ +; RUN: llvm-as %s -o - | lli -force-interpreter | grep FF8F + +; ModuleID = 'partset.c.bc' +target datalayout = "e-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-v64:64:64-v128:128:128-a0:0:64-s0:64:64-f80:128:128" +target triple = "x86_64-unknown-linux-gnu" +@.str = internal constant [4 x i8] c"%X\0A\00" ; <[4 x i8]*> [#uses=1] + +define i32 @main() nounwind { +entry: + %part_set = tail call i32 @llvm.part.set.i32.i8( i32 65535, i8 1, i32 7, i32 4 ) ; [#uses=1] + %tmp4 = tail call i32 (i8*, ...)* @printf( i8* noalias getelementptr ([4 x i8]* @.str, i32 0, i64 0), i32 %part_set ) nounwind ; [#uses=0] + ret i32 0 +} + +declare i32 @llvm.part.set.i32.i8(i32, i8, i32, i32) nounwind readnone + +declare i32 @printf(i8*, ...) nounwind -- cgit v1.2.3
