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

[Chen Gang S <gang.chen@sunrus.com.cn>]

Hello Maintainers:

After finish analyzing the related warnings for tile, for me, they are
neither tile's issues nor gcc common implementation issues:

  build/genrecog ../../gcc-tile-new/gcc/common.md ../../gcc-tile-new/gcc/config/tilegx/tilegx.md insn-conditions.md > tmp-recog.c
  ../../gcc-tile-new/gcc/config/tilegx/tilegx.md:2627: warning: operand 0 missing mode?

  ...

Tile intends to use void mode for pointer operand under tilegx, but
genrecog can not know about tile's willing, so report this warning.

Welcome any ideas, suggestions, and completions.


By the way, when cross compile tile, I found the only warning which can
let me send patch for it yesterday, and send the related patch for it
today (the last day of this month). It is really 'lucky' to me!

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.
