From 3da59db637a887474c1b1346c1f3ccf53b6c4663 Mon Sep 17 00:00:00 2001 From: Reid Spencer Date: Mon, 27 Nov 2006 01:05:10 +0000 Subject: For PR950: The long awaited CAST patch. This introduces 12 new instructions into LLVM to replace the cast instruction. Corresponding changes throughout LLVM are provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the exception of 175.vpr which fails only on a slight floating point output difference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31931 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/Transforms/InstCombine/zext.ll | 9 +++++++++ 1 file changed, 9 insertions(+) create mode 100644 test/Transforms/InstCombine/zext.ll (limited to 'test/Transforms/InstCombine/zext.ll') diff --git a/test/Transforms/InstCombine/zext.ll b/test/Transforms/InstCombine/zext.ll new file mode 100644 index 0000000000..27442aab61 --- /dev/null +++ b/test/Transforms/InstCombine/zext.ll @@ -0,0 +1,9 @@ +; Tests to make sure elimination of casts is working correctly +; RUN: llvm-as < %s | opt -instcombine -disable-output && +; RUN: llvm-as < %s | opt -instcombine | llvm-dis | notcast '' '%c1.*' + +long %test_sext_zext(short %A) { + %c1 = zext short %A to uint + %c2 = sext uint %c1 to long + ret long %c2 +} -- cgit v1.2.3
