From 2103c260f999160d0abae3a594b8b712b3935395 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Sun, 6 Mar 2005 00:08:10 +0000 Subject: [PATCH] * sysdeps/generic/ldsodefs.h (_dl_out_of_memory_internal): Remove decl. (_dl_out_of_memory): Use rtld_hidden_proto. * elf/dl-error.c (_dl_out_of_memory): Use rtld_hidden_data_def. (_dl_signal_error): Don't use INTUSE on _dl_out_of_memory. * elf/dl-open.c (_dl_open): Likewise. * elf/dl-deps.c (_dl_map_object_deps): Likewise. * sunrpc/des_impl.c (des_set_key): Make first argument unsigned char *. * elf/dl-addr.c (_dl_addr): Add a cast. * elf/unload3mod4.c: Declare foo. * elf/testobj2.c: Include . * sysdeps/gnu/errlist.awk: Emit NERR macro for _sys_nerr_internal value constant, and use it in the defn. * sysdeps/gnu/errlist-compat.awk: Use NERR in array decl. Use actual size for compat array decls. * config.make.in (cc-mtune): New substituted variable. * configure.in (libc_cv_cc_mtune): New test for -mtune= switch, done only if libc_mtune_example is defined. * configure: Regenerated. * sysdeps/i386/configure.in (libc_mtune_example): Set it. * sysdeps/i386/configure: Regenerated. * sysdeps/i386/Makefile (CFLAGS-initfini.s): Use $(cc-mtune). --- ChangeLog | 29 +++++++++++++ config.make.in | 1 + configure | 69 +++++++++++++++++++++++++++++- configure.in | 16 +++++++ elf/dl-addr.c | 3 +- elf/dl-deps.c | 4 +- elf/dl-error.c | 6 +-- elf/dl-open.c | 2 +- elf/testobj2.c | 1 + elf/unload3mod4.c | 2 + linuxthreads/ChangeLog | 4 ++ linuxthreads/sysdeps/i386/Makefile | 2 +- sunrpc/des_impl.c | 6 +-- sysdeps/generic/ldsodefs.h | 5 +-- sysdeps/gnu/errlist-compat.awk | 7 +-- sysdeps/gnu/errlist.awk | 7 +-- sysdeps/i386/Makefile | 2 +- sysdeps/i386/configure | 3 ++ sysdeps/i386/configure.in | 3 ++ 19 files changed, 149 insertions(+), 23 deletions(-) diff --git a/ChangeLog b/ChangeLog index 445b3ade0b..1aea4bb8fb 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,32 @@ +2005-03-05 Roland McGrath + + * sysdeps/generic/ldsodefs.h (_dl_out_of_memory_internal): Remove decl. + (_dl_out_of_memory): Use rtld_hidden_proto. + * elf/dl-error.c (_dl_out_of_memory): Use rtld_hidden_data_def. + (_dl_signal_error): Don't use INTUSE on _dl_out_of_memory. + * elf/dl-open.c (_dl_open): Likewise. + * elf/dl-deps.c (_dl_map_object_deps): Likewise. + + * sunrpc/des_impl.c (des_set_key): Make first argument unsigned char *. + + * elf/dl-addr.c (_dl_addr): Add a cast. + + * elf/unload3mod4.c: Declare foo. + * elf/testobj2.c: Include . + + * sysdeps/gnu/errlist.awk: Emit NERR macro for _sys_nerr_internal + value constant, and use it in the defn. + * sysdeps/gnu/errlist-compat.awk: Use NERR in array decl. + Use actual size for compat array decls. + + * config.make.in (cc-mtune): New substituted variable. + * configure.in (libc_cv_cc_mtune): New test for -mtune= switch, + done only if libc_mtune_example is defined. + * configure: Regenerated. + * sysdeps/i386/configure.in (libc_mtune_example): Set it. + * sysdeps/i386/configure: Regenerated. + * sysdeps/i386/Makefile (CFLAGS-initfini.s): Use $(cc-mtune). + 2005-03-05 Jakub Jelinek * Makerules ($(inst_libdir)/libc.so): Use $(slibdir) instead of diff --git a/config.make.in b/config.make.in index 81cb95b77f..1115460867 100644 --- a/config.make.in +++ b/config.make.in @@ -62,6 +62,7 @@ have-selinux = @have_selinux@ have-cc-with-libunwind = @libc_cv_cc_with_libunwind@ fno-unit-at-a-time = @fno_unit_at_a_time@ bind-now = @bindnow@ +cc-mtune = @cc_mtune@ static-libgcc = @libc_cv_gcc_static_libgcc@ diff --git a/configure b/configure index 1e9e50c491..f35641ac8e 100755 --- a/configure +++ b/configure @@ -313,7 +313,7 @@ ac_includes_default="\ #
