The tool chain providing binutils, gcc, gdb and a lot of other tools for the MSP430 processor

The mspgcc tool chain provides binutils, gcc, gdb and a lot of other tools for the MSP430 processor. mspgcc is formed from patches to these tools combined with a minimal libc and information describing the characteristics of the current set of MSP430 microcontrollers.

The tool chain itself consists of command line tools.

All released MSP430 microcontrollers are supported.
