// Clang doesn't support SEH on Windows yet, so for the time being we
// build this program in two parts: the code with SEH is built with CL,
// the rest is built with Clang. This represents the typical scenario when we
// build a large project using "clang-cl -fallback -fsanitize=address".
// RUN: %clang_cl_asan -O0 %p/ -Fe%t
// Check both -GS and -GS- builds:
// RUN: cl -LD -c %s -Fo%t.obj
// RUN: %clang_cl_asan -LD -O0 %s -Fe%t.dll %t.obj
// RUN: %run %t %t.dll
// RUN: cl -LD -GS- -c %s -Fo%t.obj
// RUN: %clang_cl_asan -LD -O0 %s -Fe%t.dll %t.obj
// RUN: %run %t %t.dll
#include <windows.h>
#include <assert.h>
#include <stdio.h>
// Should just "#include <sanitizer/asan_interface.h>" when C++ exceptions are
// supported and we don't need to use CL.
