The short version: People Power Company had been supporting mspgcc
revitalization as part of my work for them. I left the company in mid
February because the wireless sensor platform I'd been working on was put on
the backburner, and have spent my available time since then getting uniarch
ready for release. I have an informal job offer that would return me to
full-time employment in late April, but that work would not include open
source msp430 support.
So, whatever I can get done in the next three or four weeks will be done;
after that, I'll continue to support and enhance mspgcc but my time will be
significantly diminished.
20-bit support is a very high priority, and requires the kind of focus I
will be able to apply until mid April. I have high hopes that by leveraging
the existing work on the MSP430X branch the basics can be put in place
quickly, but if the amount of refactoring required to do this robustly is
similar to what I encountered in the last couple weeks of uniarch support
(essentially, a complete overhaul of the function prologue/epilogue code
generator), it may take a little longer.
At this time, I can't provide more clues than that: I just won't know until
I dig into it. Which may start as early as this afternoon.
