Date: Mon, 29 Mar 1999 18:36:50 -0500 From: David Edelsohn Sender: owner-linuxppc-dev@lists.linuxppc.org List-Id: What are you actually trying to accomplish? The values at pin_obj_start are not magic numbers or instructions but user-friendly values mapped at address 0. It is trying to map values 0x0 and 0XBADFCA11 (bad function call) so that dereferencing a data pointer or a PowerOpen ABI function pointer at address zero (0) will produce a visual clue. This is produced by assembly like: addr0: .long 0 .long 0xBADFCA11 And you make the linker map label addr0 at physical address 0. David [[ This message was sent via the linuxppc-dev mailing list.
