  * Porting ELF coredump for target is (quite) simple process.  First you
- * define USE_ELF_CORE_DUMP in target ELF code (where init_thread() for
+ * define HAVE_ELF_CORE_DUMP in target ELF code (where init_thread() for
  * the target resides):
  *
- * #define USE_ELF_CORE_DUMP
- *
- * Next you define type of register set used for dumping.  ELF specification
- * says that it needs to be array of elf_greg_t that has size of ELF_NREG.
+ * #define HAVE_ELF_CORE_DUMP
  *
- * typedef <target_regtype> target_elf_greg_t;
- * #define ELF_NREG <number of registers>
- * typedef taret_elf_greg_t target_elf_gregset_t[ELF_NREG];
+ * Next you define type of register set used for dumping:
+ * typedef struct target_elf_gregset_t { ... } target_elf_gregset_t;
  *
  * Last step is to implement target specific function that copies registers
  * from given cpu into just specified register set.  Prototype is:
  *
- * static void elf_core_copy_regs(taret_elf_gregset_t *regs,
- *                                const CPUArchState *env);
+ * void elf_core_copy_regs(target_elf_gregset_t *regs, const CPUArchState *env);
  *
  * Parameters:
  *     regs - copy register values into here (allocated and zeroed by caller)
