Re: [Consult] tile: How to construct testsuite for tile architecture without hardware.

[Chen Gang <xili_gchen_5257@hotmail.com>]

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.
