Optimization:

/O1 Creates small code
/O2 Creates fast code
/Oa Assumes no aliasing
/Ob Controls inline expansion
/Od Disables optimization
/Og Uses global optimizations
/Oi Generates intrinsic functions
/Op Improves floating-point consistency
/Os Favors small code
/Ot Favors fast code
/Ow Assumes aliasing across function calls
/Ox Uses maximum optimization (/Ob1gity /Gs)
/Oy Omits frame pointer

Code Generation:

/EH{s|a}[c][-] Specifies the model of exception handling
/G3 Optimizes code to favor the 386 processor. Phased out in Visual C++ 5.0, the compiler will ignore this option
/G4 Optimizes code to favor the 486 processor. Phased out in Visual C++ 5.0, the compiler will ignore this option
/G5 Optimizes code to favor the Pentium
/G6 Optimizes code to favor the Pentium Pro
/GA Optimizes code for Windows application
/GB Optimizes code to favor the Pentium processor. Blends optimizations for the 80386 (/G3), 80486 (/G4), Pentium (/G5), and Pentium Pro (/G6) options.
/Gd Uses the __cdecl calling convention
/Ge Activates stack probes
/GF
/Gf		 Enable string pooling
/Gh Calls hook function, __penter
/Gi Enables incremental compilation
/Gm Enables minimal rebuild
/GR Enables run-time type information (RTTI)
/Gr Uses the __fastcall calling convention
/Gssize Controls stack probes
/GT Supports fiber safety for data allocated using static thread-local storage
/GX[–] Enables synchronous exception handling
/Gy Enables function-level linking
/Gz Uses the __stdcall calling convention
/MD Creates a multithreaded DLL, using MSVCRT.LIB
/MDd Creates a debug multithreaded DLL, using MSVCRTD.LIB
/ML Creates a single-threaded executable file, using LIBC.LIB
/MLd Creates a debug single-threaded executable file, using LIBCD.LIB
