   Gcc however prefers to
   generate code like the following:

   la $25,<symbol>
   jalr $25

   possibly because there are problems with other MIPS assemblers.

FYI, gcc does this to permit better instruction scheduling.  Splitting
up the instructions permits, e.g., putting the la instruction in a
delay slot.  Other MIPS toolchains do extensive instruction scheduling
in the assembler, but in the GNU toolchain gcc can do a better job of
that.

Your patch looks OK to me.  The only thing I would change would be the
comments, to put ``if tempreg is PIC_CALL_REG'' before the new sample
code, as in ``or, if tempreg is PIC_CALL_REG,''.
