1998-11-26 Ulrich Drepper <drepper@cygnus.com> * sysdeps/mips/dl-machine.h (ELF_MACHINE_NO_PLT): New defined macro. (elf_machine_got_rel): Remove scope variable. Use scope from the map. Don't modify _dl_global_scope_end in the end. (__dl_runtime_resolv): Also use scope from the map. * sysdeps/mips/mips64/dl-machine.h: Likewise. * elf/dl-runtime.c: Don't define fixup and profile_fixup if ELF_MACHINE_NO_PLT is defined. * sysdeps/mips/sys/ucontext.h: New file. Patches by kaz Kojima <kkojima@rr.iij4u.or.jp>. 1998-11-26 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/generic/pselect.c (__pselect): Change interface, set/restore sigmask. * misc/sys/select.h: Change declaration according to Stevens' Unix Network Programming. * include/sys/select.h (__pselect): Likewise. Reported by <bwelling@anomaly.munge.com> [PR libc/872]. * include/fpu_control.h: New file, contains __setfpucw declaration. * sysdeps/generic/fpu_control.h: Remove __setfpucw declaration, it's an internal symbol. * sysdeps/alpha/fpu/fpu_control.h: Likewise. * sysdeps/arm/fpu/fpu_control.h: Likewise. * sysdeps/i386/fpu_control.h: Likewise. * sysdeps/m68k/fpu_control.h: Likewise. * sysdeps/powerpc/fpu_control.h: Likewise. * sysdeps/sparc/sparc32/fpu/fpu_control.h: Likewise. * sysdeps/sparc/sparc64/fpu/fpu_control.h: Likewise.
