/GA (Optimize for Windows Application)


Using /GA for an .exe file results in more efficient code for accessing thread-local storage (TLS) variables. /GA speeds access to data declared with __declspec(thread) in a Windows program. When this option is set, the __tls_index macro is assumed to be 0.

Using /GA for a DLL can result in bad code generation.
