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. --- elf/tst-tls4.c | 56 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 elf/tst-tls4.c (limited to 'elf/tst-tls4.c') diff --git a/elf/tst-tls4.c b/elf/tst-tls4.c new file mode 100644 index 0000000000..f92ee53ce5 --- /dev/null +++ b/elf/tst-tls4.c @@ -0,0 +1,56 @@ +#include +#include +#include + +#include + + +#define TEST_FUNCTION do_test () +static int +do_test (void) +{ +#ifdef USE_TLS + static const char modname[] = "tst-tlsmod2.so"; + int result = 0; + int *foop; + int (*fp) (int, int *); + void *h; + + h = dlopen (modname, RTLD_LAZY); + if (h == NULL) + { + printf ("cannot open '%s': %s\n", modname, dlerror ()); + exit (1); + } + + fp = dlsym (h, "in_dso"); + if (fp == NULL) + { + printf ("cannot get symbol 'in_dso': %s\n", dlerror ()); + exit (1); + } + + result |= fp (0, NULL); + + foop = dlsym (h, "foo"); + if (foop == NULL) + { + printf ("cannot get symbol 'foo' the second time: %s\n", dlerror ()); + exit (1); + } + if (*foop != 16) + { + puts ("foo != 16"); + result = 1; + } + + dlclose (h); + + return result; +#else + return 0; +#endif +} + + +#include "../test-skeleton.c" -- cgit 1.4.1
