From 5d787bb93e08f0536b1b7b9d53af958508c29de2 Mon Sep 17 00:00:00 2001 From: Reid Spencer Date: Fri, 23 Mar 2007 20:48:34 +0000 Subject: Add test case for testing InstCombine with arbitrary precision integer types. These tests mimic the integer test cases in the normal InstCombine test suite but use "strange" integer bit widths. Most tests written by Zhou Sheng, a few by me. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35284 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/Transforms/InstCombine/apint-mul2.ll | 13 +++++++++++++ 1 file changed, 13 insertions(+) create mode 100644 test/Transforms/InstCombine/apint-mul2.ll (limited to 'test/Transforms/InstCombine/apint-mul2.ll') diff --git a/test/Transforms/InstCombine/apint-mul2.ll b/test/Transforms/InstCombine/apint-mul2.ll new file mode 100644 index 0000000000..16518bb44e --- /dev/null +++ b/test/Transforms/InstCombine/apint-mul2.ll @@ -0,0 +1,13 @@ +; This test makes sure that mul instructions are properly eliminated. +; This test is for Integer BitWidth >= 64 && BitWidth % 2 >= 1024. +; + +; RUN: llvm-as < %s | opt -instcombine | llvm-dis | not grep mul + +implementation + +define i177 @test1(i177 %X) { + %C = shl i177 1, 155 + %Y = mul i177 %X, %C + ret i177 %Y +} -- cgit v1.2.3
