Hi all

We need a disassembler for HP Itanium. The old gnu "objdump" that we
have does not support Itanium ia64.

Question 1: does hpux 11.23 for itanium has a disassembler we can use?

Question 2: is there an "objdump" that can read ia64 formats.
> objdump -d /bin/ksh
oobjdump: /bin/ksh: File format not recognized

Question 3: (the real reason) is there a tool that tells us that 2
binaries (executable or library) has changed, regardless of any
timestamp?

Thanks in advance

Not to my knowledge.

The fact that you are asking this question tells me that you probably
need better revision control and/or automated build procedure.

Thanks,
but on my machine, /usr/local/bin/objdump does NOT exist.

Is there a swinstall depot I can get it from?

Also, about "need better revison control or automated procedure": I'm
too new at this company. Taking over a change request that was passed
on to me just because people think I can do it.

We didn't build it ourselves, so there must be some place we got
it from. I don't know what that place is though

Aha, this package has gcc-3.4.3 and binutils for ia64:
http://gatekeep.cs.utah.edu/ftp/hpux...11.23.depot.gz

HP offers a Linux emulation (AFAIK). In Linux you could disassemble using gdb,
so maybe Linux' gdb will disassemble HP-UX binaries

Maybe you can just get a native gdb for HP-UX.

"ELF64" is is in Linux, and AFAIK also in HP-UX

md5sum, or tripwire ;-)

Thanks, I'll ask the admin to swinstall it.
I'll let you know how that goes. It's Saturday.

Good funny one. Who said it first? not Jessica Simpson I presume.

You can use gdb to disassemble on HP-UX.
You can download HP gdb for Itanium from www.hp.com/go/wdb
