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

[Chen Gang S]

Hello Maintainers:

The result of gcc testsuite for tile without qemu is below, I guess the
environments construction is OK:

                  === gcc Summary ===
  
  # of expected passes            66650
  # of unexpected failures        42
  # of unexpected successes       1
  # of expected failures          107
  # of unresolved testcases       16558
  # of unsupported tests          1771

Based on normal testsuite and microblaze testsuite configuration, it is
easy to config gcc testsuite for tile. Thank gcc testsuit member and
microblaze member very much. :-)

 - Copy the original microblaze exp file as tile exp file. Export tile
   ip to /etc/hosts.

 - Change the related compiler name and related patch to tile in tile
   exp file.

 - Use tile cflag "-m64 -mcpu=tilegx -mcmodel=large -mlittle-endian"
   instead of the original microblaze cflag, in tile exp file.

If OK, I shall try to make a tile patch within this month. Next month,
I shall start tile qemu (I am preparing for it within this month). After
communicate with qemu members, I guess, it is possible to finish it.


Welcome any ideas, suggestions, and completions.

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.
