• VS Code Version: 1.112.0
• C/C++ Extension Version: 1.31.2

Bug Summary and Steps to Reproduce

Bug Summary:
_CONTROL_FLOW_GUARD defined by MSVC compiler not showing up in C++ IntelliSense properly.

From the official Microsoft documentation:
_CONTROL_FLOW_GUARD defined as 1 when the /guard:cf (Enable Control Flow Guard) compiler option is set. Otherwise, undefined.

Source: https://learn.microsoft.com/en-us/cpp/preprocessor/predefined-macros?view=msvc-170

Steps to reproduce:

1. Compile a project with control flow guard enabled

if (MSVC)
    add_compile_options(/guard:cf)
    add_link_options(/GUARD:CF)
endif()

2. Add C++ code to ensure this is being set properly.

#ifndef _CONTROL_FLOW_GUARD
#error "Control flow guard is not enabled!"
#endif

It's important to note that _MT is another predefined-macro defined by the MSVC compiler. However, that one doesn't have an IntelliSense issue.

Configuration and Logs

Can't supply log. When I ran C/C++ Log Diagnostics proprietary company info was getting logged.

This issue is super easy to reproduce I've seen it on other developers machines for a while now.

Other Extensions

Only the standard C/C++/CMake Microsoft extensions
