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

[Chen Gang]

After download and merge the all related patches to my local qemu, for
me:

 - The refactor code is really very good to me! :-)

 - It cause "hello world" test program "segment fault".

Do we need fix all related issues before merge the code?

 - If I need fix them after finish merging the refactor code into qemu
   master, please let me know, I shall try, next.

 - If it is necessary to provide related test programs, please let me
   know, I shall provide them to.

Thanks.
