Re: [Qemu-devel] [PATCH v14 00/33] TileGX basic instructions

[Chen Gang]

Hello all:

It looks tilegx still outside of qemu master tree.

I guess, I have to still use my own implementation to continue analyzing
gcc testsuite (or I am not quite sure whether I can finish analyzing
within this month).

Welcome any ideas, suggestions and completions.

Thanks.
