From 0bb2d96afee35ad4b023efc2df2791c56f68cfe6 Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Tue, 19 Feb 2002 12:40:32 +0000 Subject: [PATCH] * elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Enable absptr -> pcrel optimization for shared libs. Only create minimal .eh_frame_hdr if absptr FDE encoding in shared library cannot be converted to pcrel.
