// Tests that -fvisibility=public for Windows targets exports defined symbols

// generate DLL and import lib (public visibility by default)
// RUN: %ldc %S/inputs/fvisibility_dll_lib.d -betterC -shared -of=%t_lib.dll
// compile, link and run the app; `-dllimport=all` for dllimporting data symbols
// RUN: %ldc %s -I%S/inputs -betterC -dllimport=all %t_lib.lib -of=%t.exe
// RUN: %t.exe
