/*
 * Coff files produced by the mips loader are guaranteed to have the raw data
 * for the sections follow the headers in this order: .text, .rdata, .data and
 * .sdata the sum of the sizes of last three is the value in dsize in the
 * optional header.  This is all done for the benefit of the programs that
 * have to load these objects so only the file header and optional header
 * have to be inspected.  The macro N_TXTOFF() takes pointers to file header
 * and optional header and returns the file offset to the start of the raw
 * data for the .text section.  The raw data for the three data sections
 * follows the start of the .text section by the value of tsize in the optional
 * header.
