From 1228ed5cd520342af906f07eb1b21be82d0b40d0 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 3 Feb 1997 03:18:58 +0000 Subject: update from main archive 970202 1997-02-03 02:33 Ulrich Drepper * elf/dl-deps.c (_dl_map_object_deps): Handle multiple AUXILIARY entries. This is still no complete implementation since AUXILIARY entries in other shared objects are not yet handled. * libio/libio.h (_IO_cookie_io_functions_t): Move to C++ protected place. * po/es.po: Update. * po/fr.po: Update. * po/nl.po: Update. * time/Makefile: Better cross-compile support. Avoid test which cannot be run. (CFLAGS-tzset.c): New variable. Overwrite TZDEFAULT value from tzfile.h file. * time/tzfile.c (__tzfile_read): Allow TZDEFAULT start with '/' even in SUID programs. * time/tzset.c (__tzset_internal): If TZ envvar is not set use same default values as in tzfile.c. * elf/dynamic-link.h (elf_get_dynamic_info): Recognize versioning tags. * elf/link.h: Likewise. * elf/elf.h: Add tag definitions and data structures for versioning. 1997-02-03 02:17 Ulrich Drepper * nis/rpcsvc/yp.x (struct ypresp_key_val): There is not stupid "Sun bug". This is the order of elements also used by 4.4BSD. * nis/rpcsvc/yp.h: Likewise. Reported by HJ Lu. 1997-02-02 12:13 H.J. Lu * sunrpc/Makefile ($(objpfx)x%.h, $(objpfx)x%.c): Add "@:" as action. * Makefile (install): Pass installation directories as arguments to ldconfig. 1997-02-02 23:15 Ulrich Drepper * malloc/malloc.c (__after_morecore_hook): New variable. (malloc_extend_top): Call __after_morecore_hook if set. (main_trim): Likewise. * malloc/malloc.h: Add declaration of __after_morecore_hook. Suggested by Marcus Daniels. 1997-02-02 23:00 Marcus G. Daniels * malloc/malloc.c (rEALLOc): Protect tsd_setspecific call by #ifndef NO_THREADS. (mallinfo): Likewise. * malloc/malloc.c (__morecore): Make external since it is used in programs. 1997-02-02 15:10 Ulrich Drepper * sysdeps/unix/sysv/linux/statbuf.h (struct stat): Make st_dev field unsigned. 1997-02-01 23:36 Richard Henderson * sysdeps/alpha/stxncpy.S ($unaligned) [src % 8 > dst % 8]: Don't use t6 as a temporary; it contains bits we still need in $u_head. 1997-01-31 15:05 John Bowman * sysdeps/i386/fpu/__math.h [__USE_MISC]: Don't declare prototypes using __ prefix. Add prototype for log1p. --- elf/elf.h | 84 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 84 insertions(+) (limited to 'elf/elf.h') diff --git a/elf/elf.h b/elf/elf.h index d25934b411..05eeb3664f 100644 --- a/elf/elf.h +++ b/elf/elf.h @@ -232,6 +232,11 @@ typedef struct #define SHT_SHLIB 10 /* Reserved */ #define SHT_DYNSYM 11 /* Dynamic linker symbol table */ #define SHT_NUM 12 /* Number of defined types. */ +#define SHT_LOSUNW 0x6ffffffd /* Sun-specific low bound. */ +#define SHT_GNU_verdef 0x6ffffffd /* Version definition section. */ +#define SHT_GNU_verneed 0x6ffffffe /* Version needs section. */ +#define SHT_GNU_versym 0x6fffffff /* Version symbol table. */ +#define SHT_HISUNW 0x6fffffff /* Sun-specific high bound. */ #define SHT_LOPROC 0x70000000 /* Start of processor-specific */ #define SHT_HIPROC 0x7fffffff /* End of processor-specific */ #define SHT_LOUSER 0x80000000 /* Start of application-specific */ @@ -464,6 +469,20 @@ typedef struct #define DT_HIPROC 0x7fffffff /* End of processor-specific */ #define DT_PROCNUM DT_MIPS_NUM /* Most used by any processor */ +/* The versioning entry types.
