/*  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.
