Re: [Qemu-devel] [PULL 00/35] TileGX basic instructions

[Chen Gang]

According to RTH implementation, I am sure, his current implementation
must have fixed some issues which my original implementation  will meet,
next.

At present, I shall firstly focus on the current status - merge original
implementation to current implementation. And after comparing the test,
the result is:

  send patches directly:

    raise:       unimp (origin is ok)
    v1multu:     unimp (origin is ok)
    v4add:       unimp (origin is ok)
    vshl-vshr:   unimp (origin is ok)

  need analyzing (it is easy, I guess):

    mm:          abort (origin has no issue)
    pcnt:        abort (origin has no issue)
    v1addi:      abort (origin has no issue)

  let analyzing easier:

    try-pending: abort (origin causes pending).

I shall try to fix them, and send patches. Then continue gcc testsuite.

Thanks.
