Ceva DSP is almost same story about compiler. They used to have GCC2.95 glued to their proprietary backend, 33% of compilations results in crash :-). They got better by going to GCC4.4, but still use crazy licensing. But other DSP cores are often even worse offering as little as only assembler.

But, DSP core itself is nice, very well thought out in contrary to mainstream DSPs from TI or Freescale(now NXP).
