1997-07-26 04:14 Ulrich Drepper <drepper@cygnus.com> * elf/Makefile (distribute): Add genrtldtbl.awk. (before-compile): Add rtldtbl.h. (GAWK): New variable. (generated): Add trusted-dirs.h and rtldtbl.h. ($(objpfx)rtldtbl.h): New rule. File is needed by dl-load.c. * elf/dl-load.c: Rewrite. Now use cache and look for shared objects in machine dependent directories. * elf/dl-object.c (_dl_new_object): Initialize l_rpath_dirs member. * elf/dl-support.c: Rename function to non_dynamic_init and add initialization for _dl_platform, _dl_platformlen, _dl_pagesize and call to initializer for search path. * elf/elf.h: Add AT_PLATFORM and AT_HWCAP. * elf/genrtldtbl.awk: New file. * elf/link.h: Add type definitions and declarations for search path cache. * elf/rtld.c: Add definitions of variables used for search path cache. * sysdeps/generic/dl-sysdep.c: Let auxiliary vector initialize _dl_platform. Initialize _dl_pagesize early and use this value. * sysdeps/i386/dl-machine.h: Add code for _dl_platform handling. * sysdeps/mach/hurd/dl-sysdep.c: Initialize _dl_pagesize. * sysdeps/unix/sysv/linux/dl-sysdep.c: Use _dl_pagesize instead of calling getpagesize. * elf/dl-error.c (_dl_signal_error): Make message nicer. * nss/libnss_files.map: Fix typo. Reported by Thorsten Kukuk <kukuk@vt.uni-paderborn.de>. * sysdeps/generic/strsep.c: Optimize case where separator set contains only one character. * sysdeps/libm-ieee754/s_ccosh.c: Correct sign of result for real == +-Inf. * sysdeps/libm-ieee754/s_ccoshf.c: Likewise. * sysdeps/libm-ieee754/s_ccoshl.c: Likewise. 1997-07-25 09:15 H.J. Lu <hjl@gnu.ai.mit.edu> * sysdeps/sparc/udiv_qrnnd.S: Check PIC instead of __PIC__. * sysdeps/unix/sysv/linux/sparc/__sigtrampoline.S: Likewise. * sysdeps/unix/mips/sysdep.S: Likewise. * sysdeps/unix/sysv/linux/mips/clone.S: Likewise. * sysdeps/mips/bsd-_setjmp.S: Remove __PIC__ comment. * sysdeps/mips/bsd-setjmp.S: Likewise. * sysdeps/mips/dl-machine.h: Remove extra stuff. * sysdeps/mips/mips64/dl-machine.h: Likewise. 1997-07-25 18:55 Philip Blundell <Philip.Blundell@pobox.com> * sysdeps/standalone/arm/sysdep.c: New file. 1997-07-25 13:25 Philip Blundell <Philip.Blundell@pobox.com> * aout/Makefile: New file. * Makeconfig (binfmt-subdir): Assume a.out when not ELF. * sysdeps/generic/machine-gmon.h: Add warning about limitations of __builtin_return_address(). * sysdeps/arm/machine-gmon.h: New file, use assembly to avoid above problem. 1997-07-25 16:24 H.J. Lu <hjl@gnu.ai.mit.edu> * elf/dl-deps.c (_dl_map_object_deps): Fix a typo. 1997-07-22 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * math/libm-test.c (ccos_test, ccosh_test): Fix sign in some tests. 1997-07-24 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sunrpc/clnt_udp.c (clntudp_call): Rename cu_wait from timeout to not shadow the variable in the outer scope.
