63 * This file gives definitions supplementing <nlist.h> for permanent symbol
64 * table entries of Mach-O files. Modified from the BSD definitions. The
65 * modifications from the original definitions were changing what the values of
66 * what was the n_other field (an unused field) which is now the n_sect field.
67 * These modifications are required to support symbols in an arbitrary number of
68 * sections not just the three sections (text, data and bss) in a BSD file.
69 * The values of the defined constants have NOT been changed.
70 *
71 * These must have one of the N_STAB bits on. The n_value fields are subject
72 * to relocation according to the value of their n_sect field. So for types
73 * that refer to things in sections the n_sect field must be filled in with the
74 * proper section ordinal. For types that are not to have their n_value field
75 * relocatated the n_sect field must be NO_SECT.
