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