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.
