// This test is added to provide test coverage for the uwtable attribute. It
// aims to make sure that for an X86_64 output compiled with -fexceptions or
// -fno-exceptions, a uwtable attribute is emitted. However, for an AArch64
// output with -fexceptions a uwtable attribute is emitted, but with
// -fno-exceptions a uwtable attribute is not emitted.
// RUN: %clang -g -fexceptions --target=x86_64-apple-darwin %s -S -emit-llvm -o - | FileCheck %s --check-prefix=X86_64_UWTABLE_EXCEPTIONS
// X86_64_UWTABLE_EXCEPTIONS: attributes #0 = { {{.*}} uwtable
// X86_64_UWTABLE_EXCEPTIONS: !{{[0-9]+}} = !{i32 7, !"uwtable", i32 2}
// RUN: %clang -g -fno-exceptions --target=x86_64-apple-darwin %s -S -emit-llvm -o - | FileCheck %s --check-prefix=X86_64_UWTABLE
// X86_64_UWTABLE: attributes #0 = { {{.*}} uwtable
