x86-64 asm question

  • Subject: x86-64 asm question
  • From: Cyrus Harmon <email@hidden>
  • Date: Mon, 4 Sep 2006 15:57:46 -0700
So, using gas I'm trying to port some x86 assembly code that refers to an external symbol:

 .text
 .globl _all_threads
...
...
 mov _all_threads,%rax
...

the error  message I get is:

x86-64-assem.S:133:32-bit absolute addressing is not supported for x86-64

That works on x86 (well, with êx, of course), but I can't seem to figure out how to do this on x86-64, or any relevant docs on Apple's x86-64 assembler.

Any help would be greatly appreciated.

Thanks,

Cyrus
