From 351241c83ea67cf4cc31b3e30b952ec45c9736e1 Mon Sep 17 00:00:00 2001 From: Richard Smith Date: Thu, 7 Apr 2016 21:46:12 +0000 Subject: Replace Sema-level implementation of -fassume-sane-operator-new with a CodeGen-level implementation. Instead of adding an attribute to clang's FunctionDecl, add the IR attribute directly. This means a module built with this flag is now compatible with code built without it and vice versa. This change also results in the 'noalias' attribute no longer being added to calls to operator new in the IR; it's now only added to the declaration. It also fixes a bug where we failed to add the attribute to the 'nothrow' versions (because we didn't implicitly declare them, there was no good time to inject a fake attribute). llvm-svn: 265728 --- clang/test/CodeGenCXX/microsoft-abi-array-cookies.cpp | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'clang/test/CodeGenCXX/microsoft-abi-array-cookies.cpp') diff --git a/clang/test/CodeGenCXX/microsoft-abi-array-cookies.cpp b/clang/test/CodeGenCXX/microsoft-abi-array-cookies.cpp index 75c0621347a..9ef1879ce5f 100644 --- a/clang/test/CodeGenCXX/microsoft-abi-array-cookies.cpp +++ b/clang/test/CodeGenCXX/microsoft-abi-array-cookies.cpp @@ -7,7 +7,7 @@ struct ClassWithoutDtor { void check_array_no_cookies() { // CHECK: define void @"\01?check_array_no_cookies@@YAXXZ"() [[NUW:#[0-9]+]] -// CHECK: call noalias i8* @"\01??_U@YAPAXI@Z"(i32 42) +// CHECK: call i8* @"\01??_U@YAPAXI@Z"(i32 42) ClassWithoutDtor *array = new ClassWithoutDtor[42]; // CHECK: call void @"\01??_V@YAXPAX@Z"( @@ -24,7 +24,7 @@ void check_array_cookies_simple() { // CHECK: define {{.*}} @"\01?check_array_cookies_simple@@YAXXZ"() ClassWithDtor *array = new ClassWithDtor[42]; -// CHECK: [[ALLOCATED:%.*]] = call noalias i8* @"\01??_U@YAPAXI@Z"(i32 46) +// CHECK: [[ALLOCATED:%.*]] = call i8* @"\01??_U@YAPAXI@Z"(i32 46) // 46 = 42 + size of cookie (4) // CHECK: [[COOKIE:%.*]] = bitcast i8* [[ALLOCATED]] to i32* // CHECK: store i32 42, i32* [[COOKIE]] @@ -46,7 +46,7 @@ struct __attribute__((aligned(8))) ClassWithAlignment { void check_array_cookies_aligned() { // CHECK: define {{.*}} @"\01?check_array_cookies_aligned@@YAXXZ"() ClassWithAlignment *array = new ClassWithAlignment[42]; -// CHECK: [[ALLOCATED:%.*]] = call noalias i8* @"\01??_U@YAPAXI@Z"(i32 344) +// CHECK: [[ALLOCATED:%.*]] = call i8* @"\01??_U@YAPAXI@Z"(i32 344) // 344 = 42*8 + size of cookie (8, due to alignment) // CHECK: [[COOKIE:%.*]] = bitcast i8* [[ALLOCATED]] to i32* // CHECK: store i32 42, i32* [[COOKIE]] -- cgit v1.2.3
