Re: [Nasm-users] Unable to generate IA64 object file

[Youngman, J. <jam...@hp...>]

According to section 6.8 of the NASM Manual, IA64 is supported.

6.8 CPU: Defining CPU Dependencies

The CPU directive restricts assembly to those instructions which are available on the specified CPU.

Options are:

    * CPU IA64 IA64 CPU (in x86 mode) instruction set

Do I need to use a newer version of nasm?

Thanks
Jim

Hi Jim,

Thanks for the message I could approve! I don't know much about 64-bit 
code, but doesn't "IA64" refer to Itanium? Nasm won't do Itanium, only 
x86-64. I fear you won't be able to use it. :(

On my antique 32-bit system, I can list targets accepted by ld with 
"objdump -i" (go figure!). Possible your ld will handle x86-64 if asked 
properly?

Best,
Frank
