From 2a0a476e74b5650ebf16b061bd617ca7830ba121 Mon Sep 17 00:00:00 2001 From: JF Bastien Date: Thu, 18 Jul 2013 06:11:45 +0000 Subject: [PATCH] Fix volatile _Complex alignment test on platforms where 64-bit floating point isn't 64-bit aligned Add x86-64 triple, and check its datalayout. Also add some comments, and use the new CHECK-LABEL. llvm-svn: 186564 --- clang/test/CodeGen/volatile-complex.c | 20 ++++++++++++++------ 1 file changed, 14 insertions(+), 6 deletions(-) diff --git a/clang/test/CodeGen/volatile-complex.c b/clang/test/CodeGen/volatile-complex.c index 1240aef..15001e0 100644 --- a/clang/test/CodeGen/volatile-complex.c +++ b/clang/test/CodeGen/volatile-complex.c @@ -1,12 +1,20 @@ -// RUN: %clang_cc1 -emit-llvm %s -o - | FileCheck %s +// RUN: %clang_cc1 -triple x86_64-unknown-unknown -emit-llvm %s -o - | FileCheck %s + +// Validate that volatile _Complex loads and stores are generated +// properly, including their alignment (even when overaligned). +// +// This test assumes that floats are 32-bit aligned and doubles are +// 64-bit aligned, and uses x86-64 as a target that should have this +// datalayout. + +// CHECK: target datalayout = "{{.*}}f32:32:32-f64:64:64{{.*}}" volatile _Complex float cf; volatile _Complex double cd; volatile _Complex float cf32 __attribute__((aligned(32))); volatile _Complex double cd32 __attribute__((aligned(32))); - -// CHECK: define void @test_cf() +// CHECK-LABEL: define void @test_cf() void test_cf() { // CHECK: load volatile float* getelementptr inbounds ({ float, float }* @cf, i32 0, i32 0), align 4 // CHECK-NEXT: load volatile float* getelementptr inbounds ({ float, float }* @cf, i32 0, i32 1), align 4 @@ -19,7 +27,7 @@ void test_cf() { // CHECK-NEXT: ret void } -// CHECK: define void @test_cd() +// CHECK-LABEL: define void @test_cd() void test_cd() { // CHECK: load volatile double* getelementptr inbounds ({ double, double }* @cd, i32 0, i32 0), align 8 // CHECK-NEXT: load volatile double* getelementptr inbounds ({ double, double }* @cd, i32 0, i32 1), align 8 @@ -32,7 +40,7 @@ void test_cd() { // CHECK-NEXT: ret void } -// CHECK: define void @test_cf32() +// CHECK-LABEL: define void @test_cf32() void test_cf32() { // CHECK: load volatile float* getelementptr inbounds ({ float, float }* @cf32, i32 0, i32 0), align 32 // CHECK-NEXT: load volatile float* getelementptr inbounds ({ float, float }* @cf32, i32 0, i32 1), align 4 @@ -45,7 +53,7 @@ void test_cf32() { // CHECK-NEXT: ret void } -// CHECK: define void @test_cd32() +// CHECK-LABEL: define void @test_cd32() void test_cd32() { // CHECK: load volatile double* getelementptr inbounds ({ double, double }* @cd32, i32 0, i32 0), align 32 // CHECK-NEXT: load volatile double* getelementptr inbounds ({ double, double }* @cd32, i32 0, i32 1), align 8 -- 2.7.4
