Embedded assembler support in the compiler

The compiler enables you to include assembly code out-of-line in one or more C or C++ function definitions. Embedded assembler provides unrestricted, low-level access to the target processor, enables you to use the C and C++ preprocessor directives, and gives easy access to structure member offsets. The embedded assembler supports ARM and Thumb states.
