Richard, thanks for your offer. I welcome your partnership.
I have completed the port to mspgcc except for the following items:
The last linking hurdle, the "warning: internal error: unsupported
relocation error", remains. This is caused by a bug in mspgcc4. The
bug has been fixed but has not been integrated into the mainstream
mspgcc4 code.
It was necessary to use -Os to get the code size down to the 32Kb flash
size of the MSP430F6137 - even after eliminating all bluerobin code.
I have not implemented the intrinsic function __delay_cycles
None of the four intrinsic functions have been tested - due to the
linking problem. My first pass as these was just dummy functions to get
past the compile errors and move on to linking. I wanted to get through
the complete build procedure - compiling and linking - and then come
back to the intrinsic functions. Three of the intrinsic functions have
been implemented (they are not just dummy code / empty functions, like
__delay_cycles still is), but as mentioned have not actually been
tested. I am getting a clean compile with no errors.
I am getting the compile 'warning' in mspgcc4 signal.h
There are a couple of areas in the code where I used #ifdefined __GNUC__
to implement mspgcc specific functionality. These areas may need
refinement.
I have not placed the code in a public location, but tomorrow I will
package my work into a zip file and send it to you along with more
details about the above items.

Paul,
I ordered a TI Chronos evkit today and would like to assist with
your code port.
Have you made your code public and may I download a copy?
Have you solved your linker issue yet?
