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.
