2001-04-22 Philip Blundell <philb@gnu.org> * sysdeps/unix/sysv/linux/arm/sys/user.h (struct user_fpregs): Renamed from struct user_fp. (struct user_regs): New. (struct user): Use struct user_regs rather than struct pt_regs to avoid dependency on asm/ptrace.h. Use struct user_fpregs in place of struct user_fp and struct user_fp_struct. * sysdeps/unix/sysv/linux/arm/sys/ucontext.h: Include sys/procfs.h not sys/elf.h. 2001-04-22 Philip Blundell <philb@gnu.org> * sysdeps/unix/sysv/linux/arm/sys/elf.h: Move contents to sys/procfs.h, and tell the user to include that file instead. * sysdeps/unix/sysv/linux/arm/sys/procfs.h: Remove old cruft surrounded with #if 0. (elf_greg_t, ELF_NGREG, elf_gregset_t, elf_fpregset_t): Moved here from sys/elf.h. (prgregset_t, prfpregset_t): Define in terms of elf_gregset_t and elf_fpregset_t respectively. 2001-04-22 Philip Blundell <philb@gnu.org> * sysdeps/unix/sysv/linux/arm/register-dump.h: Also print the address that faulted.
