Update. cvs/libc-ud-970629
1997-06-29 23:43 Ulrich Drepper <drepper@cygnus.com> * config.make.in: Define need-nopic-initfini. * configure.in: Write out nopic_initfini. * csu/Makefile: Generate no-PIC crt code if need-nopic-initfini is defined. * sysdeps/i386/fpu/fraiseexcpt.c: Correct FE_INEXACT case. * sysdeps/sparc/rem.S: Get trap definition properly. * sysdeps/sparc/sdiv.S: Likewise. * sysdeps/sparc/udiv.S: Likewise. * sysdeps/sparc/urem.S: Likewise. * sysdeps/sparc/setjmp.S: Include <sys/trap.h>. * sysdeps/sparc/sys/trap.h: New file. * sysdeps/unix/sysv/linux/sparc/sys/trap.h: New file. 1997-06-25 10:26 Thorsten Kukuk <kukuk@uni-paderborn.de> * sysdeps/generic/rpc/auth.h: Add xdr_opaque_auth declaration. 1997-06-29 10:34 Fila Kolodny <fila@ibi.com> * sysdeps/mach/hurd/select.c (__select): Change MACH_MSG_SIZE_INTEGER_T to MACH_MSG_TYPE_INTEGER_T. 1997-06-29 01:04 Richard Henderson <richard@gnu.ai.mit.edu> Initial sparc64-linux support: * configure.in: Recognize sparc64 as being different from sparc. * io/ftwtest-sh: Only invoke ld.so if it exists. * math/Makefile (LDLIBS-*): Change from libm to math/libm to get static tests to link. Honour $(omit-long-double-fcts) == yes. * math/libm-test.c (test_single_exception): The argument to fetestexcept is `int' not `fexcept_t'. * shlib-versions: Recognize sparc64. * signal/signal.h: Add typedef for stack_t. * stdio-common/_itoa.c: Defaulting UMUL_TIME==UDIV_TIME is broken. Attempt to fix up most of this by cleaning up assumptions below, but give up and change the defaults. * setjmp/longjmp.c: Moved to ... * sysdeps/generic/longjmp.c: ... here. * setjmp/sigjmp.c: Moved to ... * sysdeps/generic/sigjmp.c: ... here. * sysdeps/sparc/bsd-_setjmp.S [PIC]: There wasn't even valid asm here. Ought to fix up gas to catch these silly things properly. * sysdeps/sparc/bsd-setjmp.S: Likewise. * sysdeps/unix/sysv/linux/sparc/errno.c: Remove. * sysdeps/unix/sysv/linux/sparc/kernel_sigaction.h: Remove. * sysdeps/unix/sysv/linux/sparc/kernel_stat.h: Tell xstat about the unused fields. * sysdeps/sparc/sparc64/add_n.s: Moved to ... * sysdeps/sparc64/add_n.S: ... here. Fix up %g4 and stack usage. * sysdeps/sparc/sparc64/addmul_1.s: Likewise. * sysdeps/sparc/sparc64/gmp-mparam.h: Likewise. * sysdeps/sparc/sparc64/lshift.s: Likewise. * sysdeps/sparc/sparc64/mul_1.s: Likewise. * sysdeps/sparc/sparc64/rshift.s: Likewise. * sysdeps/sparc/sparc64/sub_n.s: Likewise. * sysdeps/sparc/sparc64/submul_1.s: Likewise. * sysdeps/sparc64/Implies: New file. * sysdeps/sparc64/Makefile: Likewise. * sysdeps/sparc64/bits/endian.h: Likewise. * sysdeps/sparc64/bsd-_setjmp.S: Likewise. * sysdeps/sparc64/bsd-setjmp.S: Likewise. * sysdeps/sparc64/dl-machine.h: Likewise. * sysdeps/sparc64/elf/Makefile: Likewise. * sysdeps/sparc64/elf/crtbegin.S: Likewise. * sysdeps/sparc64/elf/crtbeginS.S: Likewise. * sysdeps/sparc64/elf/crtend.S: Likewise. * sysdeps/sparc64/elf/crtendS.S: Likewise. * sysdeps/sparc64/elf/start.S: Likewise. * sysdeps/sparc64/fpu_control.h: Likewise. * sysdeps/unix/sysv/linux/sparc64/Makefile: Likewise. * sysdeps/unix/sysv/linux/sparc64/__longjmp.S: Likewise. * sysdeps/unix/sysv/linux/sparc64/bits/setjmp.h: Likewise. * sysdeps/unix/sysv/linux/sparc64/bits/types.h: Likewise. * sysdeps/unix/sysv/linux/sparc64/brk.S: Likewise. * sysdeps/unix/sysv/linux/sparc64/clone.S: Likewise. * sysdeps/unix/sysv/linux/sparc64/fork.S: Likewise. * sysdeps/unix/sysv/linux/sparc64/getcontext.S: Likewise. * sysdeps/unix/sysv/linux/sparc64/init-first.h: Likewise. * sysdeps/unix/sysv/linux/sparc64/kernel_stat.h: Likewise. * sysdeps/unix/sysv/linux/sparc64/longjmp.S: Likewise. * sysdeps/unix/sysv/linux/sparc64/pipe.S: Likewise. * sysdeps/unix/sysv/linux/sparc64/profil-counter.h: Likewise. * sysdeps/unix/sysv/linux/sparc64/setcontext.S: Likewise. * sysdeps/unix/sysv/linux/sparc64/setjmp.S: Likewise. * sysdeps/unix/sysv/linux/sparc64/sigjmp.S: Likewise. * sysdeps/unix/sysv/linux/sparc64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/sparc64/sysdep.S: Likewise. * sysdeps/unix/sysv/linux/sparc64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sparc64/ucontext.h: Likewise. 1997-06-28 16:28 H.J.
