Subject: Re: New: Code generated references undefined symbol
These functions are part of PowerPC abi. So they should be provided by
either libgcc or the libc.

We use newlib and it is not in any of the .a or .o files installed. I
see it in the file crtresgpr.S in gcc/config/rs6000 but only
config/rs6000/t-netbsd references it. Should this code from t-netbsd be copied
to t-rtems or moved out to a new t-XXX file which is included by multiple
targets? rtems can't be the only one in need of this.

Neither.
rtems should be moved to the new style libgcc config and include
./config/rs6000/t-ppccomm .

Hmm. Doesn't RTEMS already do so?

Did you mean libgcc/config.host?
In there, powerpc-*linux is the only target using libgcc/config/rs6000/t-ppccom

Created an attachment (id=21439)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=21439&action=view)
First attempt at fix
Is this what you have in mind? I think it worked since the desired symbols
are now in libgcc.a.
Is there some other remnant in config.gcc or gcc/config/rs6000/*rtems* that
needs cleaning?
