(csinh_test): New function. (ccosh_test): New function. (cacos_test): New function. (cacosh_test): New function. (casinh_test): New function. (catanh_test): New function. (main): Add calls to csinh_test and ccosh_test. * misc/Makefile (tests): Add tst-tsearch. Add rule to link tst-tsearch against libm. * misc/tsearch.c: Rewritten to use Red-Black-Tree algorithm by Bernd Schmidt . * misc/tst-tsearch.c: New file. * stdio-common/bug5.c: Clear LD_LIBRARY_PATH environment variable before using system. * stdio-common/test-popen.c: Clear LD_LIBRARY_PATH environment variable before using popen. * sysdeps/libm-ieee754/s_cexp.c: Correct handling of special cases. * sysdeps/libm-ieee754/s_cexpf.c: Likewise. * sysdeps/libm-ieee754/s_cexpl.c: Likewise. * sysdeps/libm-i387/s_cexp.S: New file. ix87 specific implementation of complex exponential function. * sysdeps/libm-i387/s_cexpf.S: New file. * sysdeps/libm-i387/s_cexpl.S: New file. * sysdeps/libm-ieee754/s_ccosh.c: New file. Implementation of complex cosh function. * sysdeps/libm-ieee754/s_ccoshf.c: New file. * sysdeps/libm-ieee754/s_ccoshl.c: New file. * sysdeps/libm-ieee754/s_csinh.c: New file. Implementation of complex sinh function. * sysdeps/libm-ieee754/s_csinhf.c: New file. * sysdeps/libm-ieee754/s_csinhl.c: New file. * math/carg.c: New file. Generic implementatio of carg function. * math/cargf.c: New file. * math/cargl.c: New file. 1997-03-29 16:07 Ulrich Drepper * sysdeps/posix/system.c: Update copyright. 1997-03-29 04:18 Ulrich Drepper * elf/dl-error.c (_dl_catch_error): Add another argument which is passed to OPERATE. (_dl_receive_error): Likewise. * elf/link.h: Change prototypes for _dl_catch_error and _dl_receive_error to reflect above change. * elf/dl-deps.c: Don't use nested function. Call _dl_catch_error with additional argument with pointer to data. * elf/dlclose.c: Likewise. * elf/dlerror.c: Likewise. * elf/dlopen.c: Likewise. * elf/dlsym.c: Likewise. * elf/dlvsym.c: Likewise. * elf/rtld.c: Likewise. * nss/nsswitch.c: Likewise. Patch by Bernd Schmidt . 1997-03-28 21:14 Miguel de Icaza * elf/dl-error.c: Manually set up the values of "c", this avoids a call to memcpy and a zero 152 bytes structure. * sysdeps/sparc/dl-machine.h (elf_machine_rela): Test RTLD_BOOTSTRAP to avoid performing relative relocs on a second pass. * sysdeps/sparc/udiv_qrnnd.S: Make the code PIC aware. * sysdeps/unix/sysv/linux/sparc/Dist: Add kernel_stat.h and kernel_sigaction.h Add Linux/SPARC specific definitions. * sysdeps/unix/sysv/linux/sparc/fcntlbits.h: New file. * sysdeps/unix/sysv/linux/sparc/ioctls.h: New file. * sysdeps/unix/sysv/linux/sparc/kernel_sigaction.h: New file. * sysdeps/unix/sysv/linux/sparc/kernel_stat.h: New file. * sysdeps/unix/sysv/linux/sparc/sigaction.h: New file. * sysdeps/unix/sysv/linux/sparc/signum.h: New file. * sysdeps/unix/sysv/linux/sparc/termbits.h: New file. 1997-03-28 13:06 Philip Blundell * sysdeps/posix/getaddrinfo.c (gaih_inet_serv): Use __getservbyname_r() not getservbyname(). (BROKEN_LIKE_POSIX): Define to 1 so we get strict POSIX behaviour. --- elf/rtld.c | 80 ++++++++++++++++++++++++++++++++++++++++++++++++-------------- 1 file changed, 62 insertions(+), 18 deletions(-) (limited to 'elf/rtld.c') diff --git a/elf/rtld.c b/elf/rtld.c index d6bd516..6f9737e 100644 --- a/elf/rtld.c +++ b/elf/rtld.c @@ -140,6 +140,55 @@ _dl_start (void *arg) void _start (void); +/* Some helper functions. */ + +/* Arguments to relocate_doit. */ +struct relocate_args +{ + struct link_map *l; + int lazy; +}; + +struct map_args +{ + /* Argument to map_doit. */ + char *str; + /* Return value of map_doit. */ + struct link_map *main_map; +}; + +/* Arguments to version_check_doit. */ +struct version_check_args +{ + struct link_map *main_map; + int doexit; +}; + +static void +relocate_doit (void *a) +{ + struct relocate_args *args = (struct relocate_args *) a; + + _dl_relocate_object (args->l, _dl_object_relocation_scope (args->l), + args->lazy); +} + +static void +map_doit (void *a) +{ + struct map_args *args = (struct map_args *)a; + args->main_map = _dl_map_object (NULL, args->str, lt_library, 0); +} + +static void +version_check_doit (void *a) +{ + struct version_check_args *args = (struct version_check_args *)a; + if (_dl_check_all_versions (args->main_map, 1) && args->doexit) + /* We cannot start the application.
