Setting GCC 4.2.1 options in Xcode
arm, gcc, intrinsics, iphone, xcode
Solution
There are not checkboxes or menus available each option presented by the compiler, however you can enter any flags you'd like passed to the compiler in the "Other C Flags" field of the Target inspector.
Just set "Other C Flags" to "-mfloat-abi=softfp -mfpu=neon" and you'll be set.
Problem
I have a few questions about Xcode and interaction with GCC 4.2.1: It doesn't seem as if Xcode Target Properties inspector exposes all possible GCC options. Is this correct? More specifically, I'm interested in setting the "mfpu" option, as mentioned in the arm_neon.h intrinsics header. Is this possible or supported? Or perhaps set as a side-effect of some other Xcode setting? If anyone has tried this or can post some resources, it would help a lot.
