--arm

This option is a request to the compiler to target the ARM instruction set. The compiler is permitted to generate both ARM and Thumb code, but recognizes that ARM code is preferred.

Note

This option is not relevant for Thumb-only processors such as Cortex-M4, Cortex-M3, Cortex-M1, and Cortex-M0.

Default

This is the default option for targets supporting the ARM instruction set.
