From 5fe14d967045adf037e12a5945ac56de151c2ae2 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Thu, 29 Aug 2002 00:34:10 +0000 Subject: Update. * sysdeps/generic/ldsodefs.h (__rtld_global_attribute__): Define. (_rtld_global): Use it. * sysdeps/gnu/Dist: Remove errlist-compat.c. * sysdeps/gnu/Makefile (errlist-compat.c): Build this file in the object directory. Pass all Versions files to the awk script. * sysdeps/gnu/errlist-compat.c: Removed. * sysdeps/gnu/errlist.awk: Use #errlist-compat comments from the first Versions file in the search path which has them. Allow multiple errlist symbol versions to have the same count of errors. * sysdeps/gnu/errlist-compat.awk: Include instead of "errlist-compat.c". * sysdeps/gnu/errlist.c: Regenerated. * sysdeps/unix/sysv/linux/mips/Versions (libc): Add #errlist-compat comments at GLIBC_2.0, GLIBC_2.1 and GLIBC_2.3. * sysdeps/unix/sysv/linux/alpha/Versions: Likewise. (librt): Add aio_cancel and aio_cancel64 as GLIBC_2.3. * sysdeps/unix/sysv/linux/hppa/Versions: Likewise. * sysdeps/unix/sysv/linux/sparc/Versions: New file. * sysdeps/unix/sysv/linux/alpha/bits/errno.h: New file. * sysdeps/unix/sysv/linux/hppa/bits/errno.h (ECANCELED): Define to ECANCELLED if not defined by kernel headers. * sysdeps/unix/sysv/linux/bits/errno.h: Don't redefine ECANCELED if already defined by kernel headers. * sysdeps/unix/sysv/linux/sparc/bits/errno.h: New file. * sysdeps/pthread/aio_cancel.c: Don't include aio.h and its aio_cancel64 renaming hack nor provide weak_alias if aio_cancel is a macro. * Versions.def (GLIBC_2.3) [librt]: Add. * sysdeps/unix/sysv/linux/alpha/pipe.S: New file. 2002-08-28 Ulrich Drepper * include/libc-symbols.h [!__ASSEMBLER__] (declare_symbol_1): Add missing comma to .type directive. 2002-08-28 Jakub Jelinek --- sysdeps/generic/ldsodefs.h | 5 ++- sysdeps/gnu/Dist | 1 - sysdeps/gnu/Makefile | 16 ++++----- sysdeps/gnu/errlist-compat.awk | 40 +++++++++++++---------- sysdeps/gnu/errlist-compat.c | 44 ------------------------- sysdeps/gnu/errlist.awk | 2 +- sysdeps/gnu/errlist.c | 2 +- sysdeps/pthread/aio_cancel.c | 4 +++ sysdeps/unix/sysv/linux/alpha/Versions | 22 +++++++++++++ sysdeps/unix/sysv/linux/alpha/bits/errno.h | 52 ++++++++++++++++++++++++++++++ sysdeps/unix/sysv/linux/alpha/pipe.S | 1 + sysdeps/unix/sysv/linux/bits/errno.h | 6 ++-- sysdeps/unix/sysv/linux/hppa/Versions | 21 +++++++++++- sysdeps/unix/sysv/linux/hppa/bits/errno.h | 8 +++-- sysdeps/unix/sysv/linux/mips/Versions | 16 +++++++++ sysdeps/unix/sysv/linux/sparc/Versions | 25 ++++++++++++++ sysdeps/unix/sysv/linux/sparc/bits/errno.h | 52 ++++++++++++++++++++++++++++++ 17 files changed, 238 insertions(+), 79 deletions(-) delete mode 100644 sysdeps/gnu/errlist-compat.c create mode 100644 sysdeps/unix/sysv/linux/alpha/bits/errno.h create mode 100644 sysdeps/unix/sysv/linux/alpha/pipe.S create mode 100644 sysdeps/unix/sysv/linux/sparc/Versions create mode 100644 sysdeps/unix/sysv/linux/sparc/bits/errno.h (limited to 'sysdeps') diff --git a/sysdeps/generic/ldsodefs.h b/sysdeps/generic/ldsodefs.h index 06e68c2..0d85506 100644 --- a/sysdeps/generic/ldsodefs.h +++ b/sysdeps/generic/ldsodefs.h @@ -374,12 +374,14 @@ struct rtld_global EXTERN struct link_map _dl_rtld_map; #ifdef SHARED }; -extern struct rtld_global _rtld_global; +# define __rtld_global_attribute__ # ifdef IS_IN_rtld # ifdef HAVE_VISIBILITY_ATTRIBUTE # ifdef HAVE_SDATA_SECTION # define __rtld_local_attribute__ \ __attribute__ ((visibility ("hidden"), section (".sdata"))) +# undef __rtld_global_attribute__ +# define __rtld_global_attribute__ __attribute__ ((section (".sdata"))) # else # define __rtld_local_attribute__ __attribute__ ((visibility ("hidden"))) # endif @@ -388,6 +390,7 @@ extern struct rtld_global _rtld_global; # endif extern struct rtld_global _rtld_local __rtld_local_attribute__; # endif +extern struct rtld_global _rtld_global __rtld_global_attribute__; #endif #undef EXTERN diff --git a/sysdeps/gnu/Dist b/sysdeps/gnu/Dist index 9442793..526c79b 100644 --- a/sysdeps/gnu/Dist +++ b/sysdeps/gnu/Dist @@ -1,5 +1,4 @@ errlist.awk -errlist-compat.c errlist-compat.awk utmpx.h bits/utmpx.h diff --git a/sysdeps/gnu/Makefile b/sysdeps/gnu/Makefile index 65b9258..048e36a 100644 --- a/sysdeps/gnu/Makefile +++ b/sysdeps/gnu/Makefile @@ -29,24 +29,24 @@ ifeq ($(with-cvs),yes) test ! -d CVS || cvs commit -m'Regenerated from $^' $@ endif +ifeq ($(subdir),stdio-common) + vpath errlist.c $(full_config_sysdirs) -$(..)sysdeps/gnu/errlist-compat.c: errlist.c \ +$(objpfx)errlist-compat.c: errlist.c \ $(..)sysdeps/gnu/errlist-compat.awk \ - $(..)sysdeps/gnu/Versions + $(common-objpfx)Versions.v.i $(AWK) -v maxerr=`\ $(CC) -S $(CPPFLAGS) $(CFLAGS) -DNOT_IN_libc -DEMIT_ERR_MAX $< -o - \ | sed -n 's/^.*@@@[^0-9]*\([0-9]*\)[^0-9]*@@@.*$$/\1/p'` \ - -f $(filter-out $<,$^) > $@T + -f $(..)sysdeps/gnu/errlist-compat.awk \ + $(wildcard $(patsubst %,$(..)%/Versions,\ + $(config-sysdirs) $(add-ons))) > $@T # Make it unwritable so noone will edit it by mistake. -chmod a-w $@T mv -f $@T $@ -ifeq ($(with-cvs),yes) - test ! -d CVS || cvs commit -m'Regenerated from $^' $@ -endif -ifeq ($(subdir),stdio-common) # This will force the generation above to happy if need be. -$(objpfx)errlist.d: $(..)sysdeps/gnu/errlist-compat.c +$(objpfx)errlist.d: $(objpfx)errlist-compat.c endif ifeq ($(subdir),login) diff --git a/sysdeps/gnu/errlist-compat.awk b/sysdeps/gnu/errlist-compat.awk index 88b4d4f..c9a7a9c 100644 --- a/sysdeps/gnu/errlist-compat.awk +++ b/sysdeps/gnu/errlist-compat.awk @@ -29,19 +29,25 @@ # necessary compatibility symbols for older, smaller versions of sys_errlist. # -BEGIN { highest = 0 } - # These two rules catch the Versions file contents.
