From 74bd2300b57fdb2540478e8698ef7f9067db792c Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 16 Nov 2001 01:27:24 +0000 Subject: Update. 2001-10-02 Jakub Jelinek H.J. Lu * configure.in (libc_cv_gcc_static_libgcc): Set to -static-libgcc if gcc supports this flag. (EXPORT_UNWIND_FIND_FDE): Define unless target configure disables it. (gcc3): Allow glibc to be compiled with gcc 3.x. * config.h.in (EXPORT_UNWIND_FIND_FDE): Add. * config.make.in (static-libgcc, unwind-find-fde): Add. * Makerules (build-shlib-helper, build-module-helper): Use it. * scripts/versions.awk: Make sure GLIBC_ versions come first. * elf/soinit.c (__libc_global_ctors): Set tbases and dbases if necessary. (_fini): Call __deregister_frame_info_bases if __register_frame_info_bases was used to register. * elf/Versions (__register_frame_info, __deregister_frame_info): Add for GLIBC_2.0. (__register_frame_info_bases, __register_frame_info_table_bases, __deregister_frame_info_bases, _Unwind_Find_FDE): Add for GLIBC_2.2.5. * elf/Makefile (routines): Add unwind-dw2-fde. (shared-only-routines): Add unwind-dw2-fde. * sysdeps/alpha/gccframe.h: New file. * sysdeps/arm/gccframe.h: New file. * sysdeps/generic/framestate.c: New file. * sysdeps/generic/dwarf2.h: New file. * sysdeps/generic/gccframe.h (struct object): Update from gcc 3.0. * sysdeps/generic/unwind-dw2-fde.c: New file. * sysdeps/unix/sysv/linux/ia64/unwind-dw2-fde.c: New file. * sysdeps/generic/unwind-dw2-fde.h: New file. * sysdeps/generic/unwind-dw2.c: New file. * sysdeps/generic/unwind-pe.h: New file. * sysdeps/generic/unwind.h: New file. * sysdeps/hppa/gccframe.h: New file. * sysdeps/i386/gccframe.h: New file. * sysdeps/m68k/gccframe.h: New file. * sysdeps/mips/gccframe.h: New file. * sysdeps/powerpc/gccframe.h: New file. * sysdeps/s390/gccframe.h: New file. * sysdeps/sh/gccframe.h: New file. * sysdeps/sparc/gccframe.h: New file. * sysdeps/vax/gccframe.h: New file. * sysdeps/unix/sysv/linux/configure.in (libc_cv_gcc_unwind_find_fde): Set on all architectures except ia64. * sysdeps/mach/hurd/configure.in (libc_cv_gcc_unwind_find_fde): Set for i386. * sysdeps/mach/hurd/i386/Versions (__register_frame_info, __deregister_frame_info): Move to elf/Versions. * sysdeps/unix/sysv/linux/m68k/Versions: Likewise. * sysdeps/unix/sysv/linux/arm/Versions: Likewise. * sysdeps/unix/sysv/linux/alpha/Versions: Likewise. * sysdeps/unix/sysv/linux/i386/Versions: Likewise. * sysdeps/unix/sysv/linux/mips/Versions: Likewise. * sysdeps/unix/sysv/linux/powerpc/Versions: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/Versions: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/Versions: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/Versions: Likewise. * sysdeps/mach/hurd/i386/Makefile (sysdep-routines): Add framestate. * sysdeps/unix/sysv/linux/arm/Makefile: Likewise. * sysdeps/unix/sysv/linux/alpha/Makefile: Likewise. * sysdeps/unix/sysv/linux/i386/Makefile: Likewise. * sysdeps/unix/sysv/linux/m68k/Makefile: Likewise. * sysdeps/unix/sysv/linux/mips/Makefile: Likewise. * sysdeps/unix/sysv/linux/powerpc/Makefile: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/Makefile: Likewise. * sysdeps/unix/sysv/linux/sparc/Makefile: Likewise. * sysdeps/unix/sysv/linux/ia64/ldd-rewrite.sed: New file. * sysdeps/unix/sysv/linux/s390/ldd-rewrite.sed: New file. * sysdeps/generic/strnlen.c: New file. --- elf/Makefile | 5 +++++ elf/Versions | 9 +++++++++ elf/soinit.c | 24 ++++++++++++++++++++++++ 3 files changed, 38 insertions(+) (limited to 'elf') diff --git a/elf/Makefile b/elf/Makefile index 91d7e3a..b39034c 100644 --- a/elf/Makefile +++ b/elf/Makefile @@ -66,6 +66,11 @@ distribute := $(rtld-routines:=.c) dynamic-link.h do-rel.h dl-machine.h \ include ../Makeconfig +ifeq ($(unwind-find-fde),yes) +routines += unwind-dw2-fde +shared-only-routines = unwind-dw2-fde +endif + before-compile = $(objpfx)trusted-dirs.h generated := trusted-dirs.h trusted-dirs.st for-renamed/renamed.so generated-dirs := for-renamed diff --git a/elf/Versions b/elf/Versions index 2506d10..a0e691c 100644 --- a/elf/Versions +++ b/elf/Versions @@ -2,6 +2,9 @@ libc { GLIBC_2.0 { # functions used in other libraries _dl_open;
