2004-11-05 Maciej W. Rozycki <macro@mips.com> * sysdeps/mips/dl-machine.h: Include <sgidefs.h>. Use _ABIO32, _ABIN32 and _ABI64 for ABI selection throughout. * sysdeps/mips/elf/start.S: Likewise. * sysdeps/mips/mips64/__longjmp.c: Likewise. * sysdeps/mips/mips64/bsd-_setjmp.S: Likewise. * sysdeps/mips/mips64/bsd-setjmp.S: Likewise. * sysdeps/mips/mips64/setjmp.S: Likewise. * sysdeps/mips/mips64/setjmp_aux.c: Likewise. * sysdeps/mips/sys/regdef.h: Likewise. * sysdeps/mips/sys/ucontext.h: Likewise. * sysdeps/unix/mips/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/kernel-features.h: Likewise. * sysdeps/unix/sysv/linux/mips/pread.c: Likewise. * sysdeps/unix/sysv/linux/mips/pread64.c: Likewise. * sysdeps/unix/sysv/linux/mips/ptrace.c: Likewise. * sysdeps/unix/sysv/linux/mips/pwrite.c: Likewise. * sysdeps/unix/sysv/linux/mips/pwrite64.c: Likewise. * sysdeps/unix/sysv/linux/mips/sigaction.c: Likewise. * sysdeps/unix/sysv/linux/mips/sys/procfs.h: Likewise. * sysdeps/unix/sysv/linux/mips/sys/ucontext.h: Likewise. * sysdeps/mips/atomicity.h: Use _ABIO32, _ABIN32 and _ABI64 for ABI selection throughout. * sysdeps/mips/bits/setjmp.h: Likewise. * sysdeps/mips/fpu/bits/mathdef.h: Likewise. * sysdeps/mips/machine-gmon.h: Likewise. * sysdeps/mips/sys/asm.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/fcntl.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/sigcontext.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/stat.h: Likewise. * sysdeps/unix/sysv/linux/mips/kernel_stat.h: Likewise. * sysdeps/unix/sysv/linux/mips/sigcontextinfo.h: Likewise. * sysdeps/unix/sysv/linux/mips/sys/ptrace.h: Likewise. * sysdeps/unix/sysv/linux/mips/sys/tas.h: Likewise. * sysdeps/unix/sysv/linux/mips/sys/user.h: Likewise. * sysdeps/mips/sgidefs.h: Prevent <asm/sgidefs.h> from being included by kernel headers and undo its settings if already included. Define _ABIO32, _ABIN32 and _ABI64 if missing and use them to define _MIPS_SIM_ABI32, _MIPS_SIM_NABI32 and _MIPS_SIM_ABI64 for compatibility. * sysdeps/unix/sysv/linux/mips/Makefile: Use _ABIO32, _ABIN32 and _ABI64 for ABI selection in generated syscall-list.h * sysdeps/unix/sysv/linux/mips/configure.in: Use _ABIO32, _ABIN32 and _ABI64 for ABI selection in generated asm-unistd.h. * sysdeps/unix/sysv/linux/mips/configure: Regenerate. * sysdeps/unix/sysv/linux/mips/pwrite.c (__libc_pwrite): Correct an inverted _MIPS_SIM conditional.
