From 09bec94c1648d1c601a80e75ab739def1a517975 Mon Sep 17 00:00:00 2001 From: Tim Northover Date: Wed, 14 Jan 2015 01:43:33 +0000 Subject: [PATCH] ARM: add test for crc32 instructions in CodeGen. Somehow we seem to have ended up without any actual tests of the CodeGen side. Easy enough to fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225930 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/ARM/crc32.ll | 58 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 test/CodeGen/ARM/crc32.ll diff --git a/test/CodeGen/ARM/crc32.ll b/test/CodeGen/ARM/crc32.ll new file mode 100644 index 00000000000..cc94330ce65 --- /dev/null +++ b/test/CodeGen/ARM/crc32.ll @@ -0,0 +1,58 @@ +; RUN: llc -mtriple=thumbv8 -o - %s | FileCheck %s + +define i32 @test_crc32b(i32 %cur, i8 %next) { +; CHECK-LABEL: test_crc32b: +; CHECK: crc32b r0, r0, r1 + %bits = zext i8 %next to i32 + %val = call i32 @llvm.arm.crc32b(i32 %cur, i32 %bits) + ret i32 %val +} + +define i32 @test_crc32h(i32 %cur, i16 %next) { +; CHECK-LABEL: test_crc32h: +; CHECK: crc32h r0, r0, r1 + %bits = zext i16 %next to i32 + %val = call i32 @llvm.arm.crc32h(i32 %cur, i32 %bits) + ret i32 %val +} + +define i32 @test_crc32w(i32 %cur, i32 %next) { +; CHECK-LABEL: test_crc32w: +; CHECK: crc32w r0, r0, r1 + %val = call i32 @llvm.arm.crc32w(i32 %cur, i32 %next) + ret i32 %val +} + +define i32 @test_crc32cb(i32 %cur, i8 %next) { +; CHECK-LABEL: test_crc32cb: +; CHECK: crc32cb r0, r0, r1 + %bits = zext i8 %next to i32 + %val = call i32 @llvm.arm.crc32cb(i32 %cur, i32 %bits) + ret i32 %val +} + +define i32 @test_crc32ch(i32 %cur, i16 %next) { +; CHECK-LABEL: test_crc32ch: +; CHECK: crc32ch r0, r0, r1 + %bits = zext i16 %next to i32 + %val = call i32 @llvm.arm.crc32ch(i32 %cur, i32 %bits) + ret i32 %val +} + +define i32 @test_crc32cw(i32 %cur, i32 %next) { +; CHECK-LABEL: test_crc32cw: +; CHECK: crc32cw r0, r0, r1 + %val = call i32 @llvm.arm.crc32cw(i32 %cur, i32 %next) + ret i32 %val +} + + +declare i32 @llvm.arm.crc32b(i32, i32) +declare i32 @llvm.arm.crc32h(i32, i32) +declare i32 @llvm.arm.crc32w(i32, i32) +declare i32 @llvm.arm.crc32x(i32, i64) + +declare i32 @llvm.arm.crc32cb(i32, i32) +declare i32 @llvm.arm.crc32ch(i32, i32) +declare i32 @llvm.arm.crc32cw(i32, i32) +declare i32 @llvm.arm.crc32cx(i32, i64)
