What is the /FD option to cl.exe

Question

When I use Visual Studio for a C++ application, it generates a cl.exe command line with an /FD option.

But I can't find that option in the compiler documentation

Is it a legacy option? what does it do?

Answer 1

See here. It's an IDE minimal rebuild and is not exposed to users except through the property page, which is what you're seeing.

Answer 2

Thanks Matt, appreciate the time and effort.

Cheers
