Yes, it is 64 bit ELF. just run gdb on Solaris host and typed the remote target
command.

1) I can run 32-bit GDB to get reg file and thread info from the
target, even if
the image running in the target is 64-bit, I managed to talk in 32-bit.

2) However when run 64-bit GDB, I got the procfs problem.

Why GDB 64-bit needs procfs?
