>Description:
While I was looking for some GPLv2 updates for GCC
(submitted as gnu/153298), I noticed this MIPS specific
change that was committed upstream before the GPLv3 switch:
______
2007-08-20  Adam Nemet  <anemet at caviumnetworks.com>

    * config/mips/predicates.md
(const_call_insn_operand): Invoke
    SYMBOL_REF_LONG_CALL_P only on
SYMBOL_REFs.

http://gcc.gnu.org/viewcvs/branches/gcc-4_2-branch/gcc/config/mips/predicates.md?r1=117923&r2=127658&pathrev=127959
______

I have no idea of the relevance of the issue and I
don't have a MIPS platform to try this so I didn't
include it in the patchset, but it is to be the
expected behavior in upstream gcc, so I believe it
should be committed.
>How-To-Repeat:

>Fix:
The following patch applies cleanly to base gcc.
