Update.
2003-10-12 Carlos O'Donell <carlos@baldric.uwo.ca> * sysdeps/hppa/sysdep.h: Undef JUMPTARGET before use. * sysdeps/unix/sysv/linux/hppa/sysdep.h: Define PSEUDO_ERRVAL, SYSCALL_ERROR_LABEL under all conditions, INTERNAL_SYSCALL_DECL, INTERNAL_SYSCALL_ERROR_P, INTERNAL_SYSCALL_ERRNO, INTERNAL_SYSCALL, and undef JUMPTARGET before use. [PIC]: Save pic register around syscall. * sysdeps/unix/sysv/linux/hppa/sysdep.c (syscall): Cleanup asm statment. 2003-10-13 Kaz Kojima <kkojima@rr.iij4u.or.jp> * sysdeps/unix/sysv/linux/sh/sysdep.h (DO_CALL): Add SYSCALL_INST_PAD after trapa instruction.
