Hi,

For the previous analysis "libjava patches for RTEMS"[1], there are 6
cases need to pay more attention. PR18699, TLtest, Thread_Interrupt,
Thread_Sleep_2, Throw_2 and bclink.

After add patch to bdwgc for RTEMS pthread support[2]:
PR18699                PASS after Modify       [A bug in boehm-gc on
RTEMS, not related to libjava]
TLtest                    PASS
Thread_Interrupt      PASS

For the other 3 cases:
Thread_Sleep_2      PASS                       [After add patch to rtems]
Throw_2                 PASS                       [After add patch to
libjava, still need some work][3]
bclink                    UnSupport
[-findirect-dispatch do not support in this case]

I think it's time to send out the patch for review, because it may
need much time to modify. The patch is attached.

How to mark those unsupported cases as expected failures on *-*-rtems* ?

Hi,

I have add the boehm-gc patch and the configure for gcc patch to the
patch attached. So we can add this patch and then compile gcj for
RTEMS.

Best Regards,
Jie

Looks OK, but there is no ChangeLog.  Do you have copyright
assignment?

Have added ChangeLog to the patch, please see the attachment. And I
think I have copyright assignment, because I have Free Software
Foundation paperwork, as "ASSIGNMENT - GNU GCC ... JIE RT688742"

Good.  The libjava parts are OK; I can't approve the top-level part,
but it looks fine.

The build-system specific parts of the patch are OK, provided
that they have been sufficiently tested.  When committing
top-level changes, please make sure they are synced to the
src repository; if you don't have write access to src, please
ask someone who has to do that for you.

I think you still need approval for the boehm-gc related changes.

Please also try to send patches with some text MIME type.

Thanks,
Ralf

Why sys/unistd.h?

sys/unistd.h is not supposed to be accessed directly.
This likely should be a plain simple "#include <unistd.h>"
