But I am talking to a more _pure_ VLIW architecture which totally relies on static scheduling rather than EPIC architecture.

Dr. Baumgartl, Jan Parthey and folks at the Chemnitz University of Technology had got substantial success with a port for the TMS320C6x series of VLIW processors. http://archiv.tu-chemnitz.de/pub/2004/0107/data/index.html We ( A few friends and I - college students then ) had added some improvements to this port as part of undergraduate university coursework ( project). cheers!

Because of some reasons ( mainly the paucity of time) we couldnt release it to the GCC community then ( about 3 years back). - Pranav ^ permalink raw reply [flat|nested] 7+ messages in thread

We stopped when we achieved fair stability purely on the basis of the number of testsuite failures ( less than 100). cheers! Pranav ^ permalink raw reply [flat|nested] 7+ messages in thread
