             Bug #: 54805
           Summary: __gthread* on VxWorks
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: rbmj@verizon.net

patch

I originally posted this on -help, but, not getting anything back, I'm still
pretty convinced this is a bug.

Compiling for powerpc-wrs-vxworks for downloadable kernel modules, there are
issues in vxlib-tls.c, which still references __gthread*tsd*.  The only
remaining declarations, however, are to __gthread*tls*.  I added a conditional
declaration of the __gthread*tsd* functions, and also noticed that one of the
calls to __gthread_tsd_leave_dtor_context doesn't pass tcb.

Also, it says that these functions are provided by the kernel, but I haven't
been able to find any documentation to confirm this.  Can someone confirm that
these are in fact provided by the kernel?

I'm citing http://gcc.gnu.org/ml/gcc-patches/2005-08/msg01314.html for the old
prototypes.

The attached patch adds both the conditional declarations (on __RTP__) and the
minor change to the function call.  I'm not sure if this is what it *should*
do, and I have no experience in this area, so deferring to the experts here.
