From aed283dd456e7566cbfef88abe7b235ca77cc23c Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 13 Feb 2002 08:03:56 +0000 Subject: Update. 2002-02-12 Ulrich Drepper * sysdeps/generic/dl-tls.c (TLS_DTV_UNALLOCATED): Renamed from TLS_DTV_UNALLOCATE. (oom): New function. (_dl_next_tls_modid): Rewrite to handle dl_tls_dtv_slotinfo_list. (_dl_determine_tlsoffset): Likewise. (_dl_allocate_tls): Likewise. (__TLS_GET_ADDR): Define if not already defined. (_dl_tls_symaddr): New function. (allocate_and_init): New function. (__tls_get_addr): Actually implement handling of generation counter and deferred allocation. * sysdeps/generic/ldsodefs.h (_rtld_global): Remove _dl_initimage_list, add _dl_tls_dtv_slotinfo_list, _dl_tls_static_nelem, and _dl_tls_generation. Define TLS_SLOTINFO_SURPLUS and DTV_SURPLUS. Declare _dl_tls_symaddr. * sysdeps/i386/dl-tls.h: Disable __tls_get_addr handling unless SHARED. * include/link.h (struct link_map): Remove l_tls_nextimage and l_tls_previmage. * elf/dl-sym.c (_dl_sym): After successful lookup call _dl_tls_symaddr instead of DL_SYMBOL_ADDRESS for STT_TLS symbols. (_dl_vsym): Likewise. * elf/rtld.c (_dl_start_final): Adjust initdtv initialization for new layout. (dl_main): Allow PT_TLS be present for empty segment. Remove nextimage list handling. Instead add all modules using TLS to dl_tls_dtv_slotinfo_list. * elf/dl-open.c (dl_open_worker): After successfully loading all objects add those with TLS to the dl_tls_dtv_slotinfo_list list. * elf/dl-load.c (_dl_map_object_from_fd): If PT_TLS entry is for an empty segment don't do anything. Remove handling of initimage list. * elf/Versions [ld] (GLIBC_2.0): Add __libc_memalign. (GLIBC_PRIVATE): Add _dl_tls_symaddr. * elf/dl-minimal.c: Define __libc_memalign. * elf/dl-support.c: Remove _dl_initimage_list. Add _dl_tls_dtv_slotinfo_list, _dl_tls_static_nelem, and _dl_tls_generation. * include/stdlib.h: Declare __libc_memalign. * elf/Makefile: Add rules to build and run tst-tls4 and tst-tls5. * elf/tst-tls4.c: New file. * elf/tst-tls5.c: New file. * elf/tst-tlsmod2.c: New file. * elf/tls-macros.h: asms using ___tls_get_addr destroy %ecx and %edx. * elf/tst-tlsmod1.c: Don't define variables unles USE_TLS. * elf/tst-tls1.c: Use test-skeleton.c. * elf/tst-tls2.c: Likewise. * elf/tst-tls3.c: Likewise. * elf/dl-conflict.c (RESOLVE_MAP): Return NULL not 0. * sysdeps/mips/machine-gmon.h: Update MCOUNT for current GCC behavior. --- sysdeps/i386/dl-tls.h | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'sysdeps/i386') diff --git a/sysdeps/i386/dl-tls.h b/sysdeps/i386/dl-tls.h index 8e30530542..5066b8dcd6 100644 --- a/sysdeps/i386/dl-tls.h +++ b/sysdeps/i386/dl-tls.h @@ -17,6 +17,7 @@ Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA. */ + /* Type used for the representation of TLS information in the GOT. */ typedef struct { @@ -25,6 +26,7 @@ typedef struct } tls_index; +#ifdef SHARED /* This is the prototype for the GNU version. */ extern void *___tls_get_addr (tls_index *ti) __attribute__ ((__regparm__ (1))); @@ -46,5 +48,7 @@ __tls_get_addr (tls_index *ti) /* Prepare using the definition of __tls_get_addr in the generic version of this file. */ -#define __tls_get_addr __attribute__ ((__regparm__ (1))) ___tls_get_addr +# define __tls_get_addr __attribute__ ((__regparm__ (1))) ___tls_get_addr strong_alias (___tls_get_addr, ___tls_get_addr_internal) +# define __TLS_GET_ADDR ___tls_get_addr +#endif -- cgit v1.2.3
