27 * Definitions to generate Intel SVR4-like core files.
28 * These mostly have the same names as the SVR4 types with "elf_"
29 * tacked on the front to prevent clashes with linux definitions,
30 * and the typedef forms have been avoided. This is mostly like
31 * the SVR4 structure, but more Linuxy, with things that Linux does
32 * not support and which gdb doesn't really use excluded.
33 * Fields present but not used are marked with "XXX".
