/* vectors.s 1.1 - 95/12/04
*
* This file contains the assembly code for the PowerPC
* interrupt veneers for RTEMS.
*
*/
/*
* The issue with this file is getting it loaded at the right place.
* The first vector MUST be at address 0x????0100.
* How this is achieved is dependant on the tool chain.
*
* However the basic mechanism for ELF assemblers is to create a
* section called ".vectors", which will be loaded to an address
* between 0x????0000 and 0x????0100 (inclusive) via a link script.
*
* The basic mechanism for XCOFF assemblers is to place it in the
* normal text section, and arrange for this file to be located
* at an appropriate position on the linker command line.
*
* The variable 'PPC_VECTOR_FILE_BASE' must be defined to be the
* offset from 0x????0000 to the first location in the file. This
* will usually be 0x0000 or 0x0100.
