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?

No, that is not what I said.  You should build GDB and
specify a
sparc64-elf --target.

Using target remote from a native GDB is supposed to work,
but does
not always.
