Compiler and processor support for bit-banding

The compiler supports bit-banding for processors that provide the feature.

The compiler supports bit-banding in the following ways:

  • __attribute((bitband)) language extension.

  • --bitband command-line option.

Bit-banding is a feature of the Cortex-M3 and Cortex-M4 processors ( --cpu=Cortex-M3 and --cpu=Cortex-M4 ) and some derivatives (for example, --cpu=Cortex-M3-rev0 ). This functionality is not available on other ARM processors.
