// 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".
|
|
//
|
|
// Check both -GS and -GS- builds:
|
|
// RUN: cl -c %s -Fo%t.obj
|
|
// RUN: %clangxx_asan -o %t.exe %s %t.obj
|
|
// RUN: %run %t.exe
|
|
//
|
|
// RUN: cl -GS- -c %s -Fo%t.obj

// RUN: %clangxx_asan -o %t.exe %s %t.obj
