From 2106badea341062643d4e11d6e9975b871fa61b9 Mon Sep 17 00:00:00 2001 From: Chandler Carruth Date: Mon, 12 Dec 2011 11:23:11 +0000 Subject: Add an explicit test of the auto-upgrade functionality for the new intrinsic syntax. Now that this is explicitly covered, I plan to upgrade the existing test suite to use an explicit immediate. Note that I plan to specify 'true' in most places rather than the auto-upgraded value as that is the far more common value to end up here as that is the value coming from GCC's builtins. The only place I'm likely to put a 'false' in is when testing x86 which actually has different instructions for the two variants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146369 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/Assembler/auto_upgrade_intrinsics.ll | 44 +++++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 test/Assembler/auto_upgrade_intrinsics.ll (limited to 'test/Assembler') diff --git a/test/Assembler/auto_upgrade_intrinsics.ll b/test/Assembler/auto_upgrade_intrinsics.ll new file mode 100644 index 0000000000..7ad5cc30fa --- /dev/null +++ b/test/Assembler/auto_upgrade_intrinsics.ll @@ -0,0 +1,44 @@ +; Test to make sure intrinsics are automatically upgraded. +; RUN: llvm-as < %s | llvm-dis | FileCheck %s + +declare i8 @llvm.ctlz.i8(i8) +declare i16 @llvm.ctlz.i16(i16) +declare i32 @llvm.ctlz.i32(i32) +declare i42 @llvm.ctlz.i42(i42) ; Not a power-of-2 + +define void @test.ctlz(i8 %a, i16 %b, i32 %c, i42 %d) { +; CHECK: @test.ctlz + +entry: + ; CHECK: call i8 @llvm.ctlz.i8(i8 %a, i1 false) + call i8 @llvm.ctlz.i8(i8 %a) + ; CHECK: call i16 @llvm.ctlz.i16(i16 %b, i1 false) + call i16 @llvm.ctlz.i16(i16 %b) + ; CHECK: call i32 @llvm.ctlz.i32(i32 %c, i1 false) + call i32 @llvm.ctlz.i32(i32 %c) + ; CHECK: call i42 @llvm.ctlz.i42(i42 %d, i1 false) + call i42 @llvm.ctlz.i42(i42 %d) + + ret void +} + +declare i8 @llvm.cttz.i8(i8) +declare i16 @llvm.cttz.i16(i16) +declare i32 @llvm.cttz.i32(i32) +declare i42 @llvm.cttz.i42(i42) ; Not a power-of-2 + +define void @test.cttz(i8 %a, i16 %b, i32 %c, i42 %d) { +; CHECK: @test.cttz + +entry: + ; CHECK: call i8 @llvm.cttz.i8(i8 %a, i1 false) + call i8 @llvm.cttz.i8(i8 %a) + ; CHECK: call i16 @llvm.cttz.i16(i16 %b, i1 false) + call i16 @llvm.cttz.i16(i16 %b) + ; CHECK: call i32 @llvm.cttz.i32(i32 %c, i1 false) + call i32 @llvm.cttz.i32(i32 %c) + ; CHECK: call i42 @llvm.cttz.i42(i42 %d, i1 false) + call i42 @llvm.cttz.i42(i42 %d) + + ret void +} -- cgit v1.2.3
