How can I remove the -mthumb compiler flag in XCode?

Question

I've been reading that by default there is an -mthumb compiler flag which reduces code size by 35%. However, in a floating-point calculation intensive app like mine, this is not an good option, like apple says. I'd like to try it out if it changes anything.

Search for "thumb" in the target options and uncheck the box.
