2003-02-07 Kaz Kojima <kkojima@rr.iij4u.or.jp> * elf/tls-macros.h: Add non-PIC TLS macros and fix clobber list for SH. * sysdeps/unix/sysv/linux/sh/brk.c: Add SYSCALL_INST_PAD after the trapa instruction. * sysdeps/unix/sysv/linux/sh/clone.S (__clone): Add additional parameters. * sysdeps/unix/sysv/linux/sh/sh4/sysdep.h: New file. (NEED_SYSCALL_INST_PAD): Define. * sysdeps/unix/sysv/linux/sh/sys/user.h (start_thread): Undef to avoid to use definition for the kernel. * sysdeps/unix/sysv/linux/sh/sysdep.h (SYSCALL_ERROR_HANDLER): Save and restore the frame pointer. (SYSCALL_INST_PAD): Define. (INLINE_SYSCALL): Make use of INTERNAL_SYSCALL. (INTERNAL_SYSCALL): Make use of ERR parameter. Add SYSCALL_INST_PAD after trapa instruction. (INTERNAL_SYSCALL_DECL, INTERNAL_SYSCALL_ERRNO, INTERNAL_SYSCALL_ERROR_P): Adjust accordingly.
