2.5. Specifying the target processor or architecture

RVCT includes support for all ARM architectures from ARMv4 onwards, including ARM NEON™ technology. All architecture names prior to ARMv4 are now obsolete and no longer supported.

Specifying a target processor or architecture enables the compiler to take advantage of extra features specific to the selected processor or architecture. Use the --cpu and --fpu options to enable these features.

You can also specify the startup instruction set by using the --arm or --thumb option.
