To: qemu-devel; +Cc: peter.maydell, gang.chen.5i5j, Chen Gang
From: Chen Gang <xili_gchen_5257@hotmail.com>
They are based on Linux kernel tilegx architecture for 64 bit binary,
and also based on tilegx ABI reference document, and also reference from
other targets implementations.

From: Chen Gang <xili_gchen_5257@hotmail.com>
Add main working flow feature, system call processing feature, and elf64
tilegx binary loading feature, based on Linux kernel tilegx 64-bit
implementation.
[rth: Moved all of the implementation of atomic instructions to a later patch.]

OK, thanks. I got them in qemu master tree, and they have passed several
simple tests.
Next, I shall send several patches based on it (except floating point
insns) for my current steps.
Then continue to test gcc testsuite, hope we can finish it within this
month.
Thanks.

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.

After fix v1addi issue, try-pending will cause segment fault instead of
abort, I shall continue analyzing try-pending issue, next.

After we check the zero dest register for ld insns, this issue can be
fixed -- at least, it is not tilegx's issue, tilegx can bypass it
successfully.
Next I shall continue for gcc testsuite. I am not quite sure whether I
can finish it within this month, but I guess, I shall finish it within
Chinese National Day (which I can get more free time resources on it).
Thanks.
