This is related to my "D'oh post" regarding the Cortex M4 floating point size.
According to ARM, the Cortex R4 supports double-precision floating point, and it looks like it's maybe more amenable to embedding than the Cortex Ax cores. I really want to find a chip that I can just lick the back of and stick onto a board, rather than something that'll become the CPU in a built-up computer with external memory and all that razz-matazz.
TI has a Cortex R4 part, but I've used the predecessor part and the only tools available for it were from Keil -- I dislike single-sourcing, and I'd much prefer using Gnu tools if there are such for the R4.
So, has anyone used the R4? Do you happen to know if the Gnu tools support it well? Can you recommend any off the shelf embedded processors that use it? (TI included -- just because the SM470R1B1M was hard to work with doesn't mean that TI hasn't solved those problems with their Cortex version).
