printmethod.exp FAIL

Hello all,

One case FAIL in printmethod.exp when running GDB testsuite
for SCORE. 
When testing "print theA->virt", the message
GDB print is not expected.
I found the problem happen at cp_print_class_method ().

cp_print_class_method () will call
METHOD_PTR_IS_VIRTUAL(addr) to 
determine how to print theA->virt. Here, addr is address
of theA->virt. 
Also, #define METHOD_PTR_IS_VIRTUAL(ADDR)  ((ADDR) &
0x80000000).
In my test, if addr <= 0x80000000, the case is PASS,
otherwise FAIL.
Why does this tie to 0x80000000?

Please try a newer version of GDB.  METHOD_PTR_IS_VIRTUAL
was for an
old implementation of C++ (either HP or early g++); I
removed it a
year or two ago.
