1997-08-14 03:14 Ulrich Drepper <drepper@cygnus.com> * elf/dl-minimal.c: Don't use relative #include paths. (malloc): Don't try to initialize _dl_pagesize, it already is. (__sigjmp_save, longjmp): Reformat. * sysdeps/generic/dl-sysdep.c: Implement _dl_show_auxv function to show content of auxiliary array. (_dl_sysdep_start): Remember start of auxiliary vector. * sysdeps/mach/hurd/dl-sysdep.c: (_dl_show_auxv): New dummy function. * elf/link.h: Add prototype for _dl_show_auxv. * elf/rtld.c (dl_main): Call _dl_show_auxv if LD_SHOW_AUXV envvar is present. * libio/iofdopen.c: Better prepare for use in libstdc++. * libio/iofflush.c: Likewise. * libio/iofgetpos.c: Likewise. * libio/iofgets.c: Likewise. * libio/iofopen.c: Likewise. * libio/iofputs.c: Likewise. * libio/iofread.c: Likewise. * libio/iofsetpos.c: Likewise. * libio/ioftell.c: Likewise. * libio/iofwrite.c: Likewise. * libio/iogetdelim.c: Likewise. * libio/iogets.c: Likewise. * libio/iopopen.c: Likewise. * libio/ioputs.c: Likewise. * libio/iosetbuffer.c: Likewise. * libio/iosetvbuf.c: Likewise. * libio/ioungetc.c: Likewise. * libio/iovsprintf.c: Likewise. * libio/iovsscanf.c: Likewise. * manual/creature.texi: Mention _XOPEN_SOURCE_EXTENDED in correct place. * manual/math.texi: Add comment to sincos decsription to say it's a GNU extension. Fix description of random function. * posix/fnmatch.h: Recognize Windog by _WINDOWS32 not WIN32. * posix/glob.c: Likewise. Handle stupid system headers on SunOS.

(if_nametoindex, if_nameindex): Fix ENOSYS setting. 1997-08-11 11:58 Richard Henderson <rth@cygnus.com> Sparc ISO C 9x exception handling: * sysdeps/sparc/fpu/bits/mathdef.h: New file. * sysdeps/sparc/fpu/fclrexcpt.c: New file. * sysdeps/sparc/fpu/fegetenv.c: New file. * sysdeps/sparc/fpu/fegetround.c: New file. * sysdeps/sparc/fpu/feholdexcpt.c: New file. * sysdeps/sparc/fpu/fesetenv.c: New file. * sysdeps/sparc/fpu/fesetround.c: New file. * sysdeps/sparc/fpu/feupdateenv.c: New file. * sysdeps/sparc/fpu/fgetexcptflg.c: New file. * sysdeps/sparc/fpu/fraiseexcpt.c: New file. * sysdeps/sparc/fpu/fsetexcptflg.c: New file. * sysdeps/sparc/fpu/ftestexcept.c: New file. * sysdeps/sparc/sparc32/fpu/bits/fenv.h: New file. * sysdeps/sparc/sparc64/fpu/bits/fenv.h: New file. 1997-08-11 11:58 Richard Henderson <rth@cygnus.com> Sparc64 merge: * configure.in: Change up subdirectories, rename sparc8->sparcv8. * csu/Makefile: Nuke need-nopic-initfini bits. The problem was that sparc64 ld did not recognize pic relocs at all. * elf/dl-deps.c: Include <string.h>. * elf/do-rel.h (elf_dynamic_do_rel): Take reloc address and size directly instead of the DT names to get them from. * elf/dynamic-link.h (_ELF_DYNAMIC_DO_RELOC): New macro distilled from ELF_DYNAMIC_DO_REL{,A}. Define a second version that accounts for the possibility that DT_RELA and DT_JMPPLT overlap, as such is the case on the Sparc. * elf/elf.h: Stub out Elf64_Ver*, and make them the same as the Elf32_Ver* bits. The linker does not even know to differentiate between the word sizes. Someone should examine this and figure out what the proper sizes of things should be for 64-bit hosts before the sparc64 libraries are distributed. * shlib-versions: Rename sparc64 ld.so to not conflict with sparc32 on the same machine. Move old sysdeps/sparc contents to sysdeps/sparc/sparc32, rename sparc8 subdir to sparcv8, move sysdeps/sparc64 content to sysdeps/sparc/sparc64. Same for sysdeps/unix/sysv/linux/sparc. * sysdeps/sparc/Implies: Do ieee754 here. * sysdeps/sparc/configure.in: Move from sparc32/. * sysdeps/sparc/sparc32/Implies: Do wordsize here. * sysdeps/sparc/sparc64/Implies: Likewise. * sysdeps/sparc/sparc32/dl-machine.h (elf_machine_load_address): Use uninitialized .got to find load address instead of AT_BASE, as the later does not exist when running ld.so directly. * sysdeps/sparc/sparc32/fpu/fpu_control.h: Move from ../. * sysdeps/sparc/sparc64/fpu/fpu_control.h: Likewise. * sysdeps/sparc/sparc32/udiv_qrnnd.S: Clean up PIC support. * sysdeps/sparc/sparc64/Makefile (sysdep_routines): Add s_finitel and s_signbitl for stdio. * sysdeps/sparc/sparc64/configure.in: Remove, we no longer need nopic_initfini. * sysdeps/sparc/sparc64/bsd-_setjmp.S: Remove. * sysdeps/sparc/sparc64/bsd-setjmp.S: Remove. * sysdeps/unix/sysv/linux/sparc/sparc64/bsd-_setjmp.S: New empty file. * sysdeps/unix/sysv/linux/sparc/sparc64/bsd-setjmp.S: New empty file. * sysdeps/unix/sysv/linux/sparc/sparc64/longjmp.S: Add __longjmp alias. * sysdeps/unix/sysv/linux/sparc/sparc64/setjmp.S: Add weak _setjmp and setjmp entry points. * sysdeps/sparc/sparc64/dl-machine.h: Finish real implementation. * sysdeps/sparc/sparc64/elf/crtbegin.S: Add copyright, fix PIC. * sysdeps/sparc/sparc64/elf/crtend.S: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/sigaction.h (struct sigaction): Fix sa_flags size for sparc64; add sa_restorer for kernel. * sysdeps/unix/sysv/linux/sparc/sparc64/brk.S: Fix PIC. * sysdeps/unix/sysv/linux/sparc/sparc64/clone.S: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/init-first.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/syscall.S: New file. 1997-08-10 18:29:08 1997 Mark Kettenis <kettenis@phys.uva.nl> * login/login.c (login): Check for correct return value of utmpname. 1997-08-11 16:49 Ulrich Drepper <drepper@cygnus.com> * time/tzset.c (__tzset_internal): Correctly handle TZ strings following incorrect old POSIX specs. Patch by Paul Eggert <eggert@twinsun.com>. * sysdeps/generic/bits/sigaction.h: Correct comment for SA_RESTART. * sysdeps/unix/bsd/osf/bits/sigaction.h: Likewise. * sysdeps/unix/sysv/linux/alpha/bits/sigaction.h: Likewise. * sysdeps/unix/sysv/linux/bits/sigaction.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/sigaction.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/sigaction.h: Likewise. * sysdeps/unix/sysv/minix/bits/sigaction.h: Likewise. * sysdeps/unix/sysv/sysv4/bits/sigaction.h: Likewise. Reported by NIIBE Yutaka <gniibe@mri.co.jp>. 1997-08-09 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * manual/math.texi: Define the macros @mul and @infinity and use them to format the multiplication and infinity signs. (FP Comparison Functions): Use @code, not @math, for C code examples. * elf/dl-profile.c: Add descriptions and implement reading of
