From 39e16978c3b4ac8eaf2201fac56316623910d9da Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 29 Aug 1997 01:19:12 +0000 Subject: Update. 1997-08-29 02:36 Ulrich Drepper * Makefile (version-info.h): Use ISO form for the date. * catgets/catgetsinfo.h: Include . (struct catalog_obj): Add lock field. (__open_catalog): Remove second parameter from prototype. * catgets/catgets.c (catopen): Initialize lock field. (catgets): Don't pass second parameter to __open_catalog. * catgets/gencat.c: Initialize lock field and don't pass second parameter to __open_catalog. * catgets/open_catalog.c (__open_catalog): Decide about use of path by examining path in struct, not based on extra argument. Acquire a the lock before trying to load the catalog and release it before returning. * csu/Makefile (abi-tag.h): Make sure target directory exists. * io/Makefile (headers): Add bits/poll.h. * io/sys/poll.h: Remove definitions of POLL* constants. Include . * sysdeps/generic/bits/poll.h: New file. * sysdeps/unix/sysv/linux/bits/poll.h: New file. * sysdeps/unix/sysv/linux/m68k/bits/poll.h: New file. * sysdeps/unix/sysv/linux/mips/bits/poll.h: New file. * sysdeps/unix/sysv/linux/sparc/bits/poll.h: New file. * libio/fileops.c (_IO_file_read, _IO_file_write): Remove dead code. * malloc/obstack.c: Add casts to keep very verbose compilers on 64bit machine quiet. * nss/Makefile (libnss_db.so): Find libdb.so in db2 directory. 1997-08-28 17:30 Ulrich Drepper * catgets/catgets.c (catopen): Correctly determine length of string in NLSPATH evironment variable. Patch by HJ Lu . 1997-08-27 23:19 Richard Henderson * sysdeps/generic/dl-sysdep.c (DL_FIND_ARG_COMPONENTS): Provide default macro to track down arguments from stack start. (_dl_sysdep_start): Use it. * sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Truncate to simply providing a special DL_FIND_ARG_COMPONENTS and including the next file up the line. * sysdeps/powerpc/e_sqrt.c: Move contents to w_sqrt.c and provide stub. * sysdeps/powerpc/e_sqrtf.c: Likewise. * sysdeps/powerpc/s_copysignf.S: Provide empty file; symbol is with the double precision version. * sysdeps/powerpc/s_fabsf.S: Likewise. * sysdeps/powerpc/s_isnanf.S: Likewise. --- sysdeps/generic/dl-sysdep.c | 27 ++++++++++++++++++--------- 1 file changed, 18 insertions(+), 9 deletions(-) (limited to 'sysdeps/generic/dl-sysdep.c') diff --git a/sysdeps/generic/dl-sysdep.c b/sysdeps/generic/dl-sysdep.c index b942e40f7a..7ee3002314 100644 --- a/sysdeps/generic/dl-sysdep.c +++ b/sysdeps/generic/dl-sysdep.c @@ -45,6 +45,21 @@ int __libc_multiple_libcs; /* Defining this here avoids the inclusion of init-first. */ static ElfW(auxv_t) *_dl_auxv; + +#ifndef DL_FIND_ARG_COMPONENTS +#define DL_FIND_ARG_COMPONENTS(cookie, argc, argv, envp, auxp) \ + do { \ + void **_tmp; \ + (argc) = *(long *) cookie; \ + (argv) = (char **) cookie + 1; \ + (envp) = (argv) + (argc) + 1; \ + for (_tmp = (void **) (envp); *_tmp; ++_tmp) \ + continue; \ + (auxp) = (void *) ++_tmp; \ + } while (0) +#endif + + ElfW(Addr) _dl_sysdep_start (void **start_argptr, void (*dl_main) (const ElfW(Phdr) *phdr, ElfW(Word) phnum, @@ -60,21 +75,15 @@ _dl_sysdep_start (void **start_argptr, gid_t egid = 0; unsigned int seen; + DL_FIND_ARG_COMPONENTS (start_argptr, _dl_argc, _dl_argv, _environ, _dl_auxv); + user_entry = (ElfW(Addr)) &ENTRY_POINT; - _dl_argc = *(long *) start_argptr; - _dl_argv = (char **) start_argptr + 1; - _environ = &_dl_argv[_dl_argc + 1]; _dl_platform = NULL; /* Default to nothing known about the platform. */ - start_argptr = (void **) _environ; - while (*start_argptr) - ++start_argptr; seen = 0; #define M(type) (1 << (type)) - for (av = _dl_auxv = (void *) ++start_argptr; - av->a_type != AT_NULL; - seen |= M ((++av)->a_type)) + for (av = _dl_auxv; av->a_type != AT_NULL; seen |= M ((++av)->a_type)) switch (av->a_type) { case AT_PHDR: -- cgit v1.2.3
