Retargetable Compiler Environment for DSPs?

Hello everybody,


In a research project we have developed a processor description
environment from which several processor related tools can be
generated (retargetted). The architectural focus is on digital signal
processors and not on general purpose architectures. What is still
missing is a way to generate a compiler or at least compiler
components for DSPs.


Currently I am searching for a compiler "environment" that is suitable
for my ideas. I am currently thinking of gcc, suif or CoSy (which is
highly commercial: http://www.ace.nl)


I would like to know how suited these environments are for DSP
properties/features like:
VLIW architecture
softwarepipelining
conditional execution
SIMD instructions
special purpose units (like MAC or FIR units)
...


I am also interested in other environments that are suited, too.


Greetings,
Oliver Wahlen




P.S.: I asked this question in the gcc mailing list but did not get an
answer. I would appreciate an input where/whom to ask this question.
