From aa9df0b0c3cef33514095bde2eedead986677955 Mon Sep 17 00:00:00 2001 From: Mon P Wang Date: Wed, 18 Mar 2009 06:24:04 +0000 Subject: Added missing support for widening when splitting an unary op (PR3683) and expanding a bit convert (PR3711). In both cases, we extract the valid part of the widen vector and then do the conversion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67175 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/PowerPC/pr3711_widen_bit.ll | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) create mode 100644 test/CodeGen/PowerPC/pr3711_widen_bit.ll (limited to 'test/CodeGen/PowerPC/pr3711_widen_bit.ll') diff --git a/test/CodeGen/PowerPC/pr3711_widen_bit.ll b/test/CodeGen/PowerPC/pr3711_widen_bit.ll new file mode 100644 index 0000000..e601e96 --- /dev/null +++ b/test/CodeGen/PowerPC/pr3711_widen_bit.ll @@ -0,0 +1,18 @@ +; RUN: llvm-as < %s | llc -march=ppc32 -mcpu=g5 + +; Test that causes a abort in expanding a bit convert due to a missing support +; for widening. + +define i32 @main() nounwind { +entry: + br i1 icmp ne (i32 trunc (i64 bitcast (<2 x i32> to i64) to i32), i32 2), label %bb, label %bb1 + +bb: ; preds = %entry + tail call void @abort() noreturn nounwind + unreachable + +bb1: ; preds = %entry + ret i32 0 +} + +declare void @abort() noreturn nounwind -- cgit v1.1
