/Ox (Full Optimization)

/Ox

/Ox combines optimizing options to produce code that favors execution speed over smaller code size. /Ox can be combined with /Os (/Oxs) to favor smaller code size (optimize for size).

In general, /O2 should be preferred over /Ox and /O1 over /Oxs.

The effect is the same as using the following options:

• /Obn, where n = 2
• /Og
• /Oi
• /Os, /O, /Ot
• /Oy

  Note   The use of Full Optimization implies the use of the Frame Pointer Omission (/Oy) option.

/Ox is mutually exclusive from:

• /O1
• /O2
• /Od
