mipsbe solib event breakpoint endian?

[Kris Warkentin]

Finally got around to chasing this again and I've found the problem.  I'm
hoping someone might be able to explain why I'm seeing what I'm seeing.

GDB-5.2.1 targetting QNX MipsBE:
Breakpoint 4, enable_break () at ../../gdb/solib-svr4.c:939
939           if (!load_addr_found)
(top) n
940             load_addr = read_pc () - tmp_bfd->start_address;
(top) p read_pc()
$1 = 1882417036
(top) p /x read_pc()
$2 = 0x7033678c
(top)


GDB-HEAD targetting QNX MipsBE:
Breakpoint 3, enable_break () at ../../gdb/solib-svr4.c:1039
1039            load_addr = read_pc () - tmp_bfd->start_address;
(top) p read_pc()
$1 = 8084919611063009279
(top) p /x read_pc()
$2 = 0x7033678ceeffffff
(top)

Looks like someone thinks the program counter is a 64 bit value....  Any
hints?

cheers,

Kris
