At present, tilegx is integrated into qemu master branch successfully
with the much help by qemu members.
But sorry, I did not finish gcc testsuite in time, the main excuse is
- I am busy on the normal work -- sometimes, have to do overtime work.
(my company started up an urgent project, but couldn't find suitable
persons for it in short time, so I have to do it during these days).
Next, in Chinese National Day, I have enough free time resources on open
source, hope I finish our gcc testsuite within Chinese National Day (it
is from 2015-10-01 -- 2015-10-07).
Thanks.

A qemu port for tile hardware would certainly be welcome, but to my knowledge, no one has completed such a port yet. ISA and ABI documentation for tilegx are available at www.tilera.com/scm.
