Folks,
Back in '94 I ported gcc/g++ 2.5.8 to the TMS34010. This was a
specialised CISC graphics processor from Texas Instruments.
The 34k was bit-addressable. Perhaps this is still the only port of GCC
to a bit-addressable architecture?
It was a _lot_ of work - in many places the compiler assumes that adding
one to a pointer advances it by eight bits, not by one bit.
Apart from doing the md and tm.h stuff, most of the work was in hunting
down and nailing those assumptions. This would still be useful for
someone who was porting a current version to a bit-addressable
architecture.
So. Is anyone interested in taking this historical curiosity off my
hands, or do I take it to my grave?
Cheers,
Andrew.
