Hi, This patch adds code to fix output local symbol count fo an object after relaxation. This is required if one of its input sections is discarded or shrunk by EXIDX entry merging. To avoid unnecessary updating, we mark an object if an EXIDX input section of it is either dropped or relaxed. At the end of relaxation, we update the output local symbol counts of such marked objects. This done only for ARM in the relaxation hook and does not affect performance of other targets. -Doug 2010-01-28 Doug Kwan <dougkwan@google.com> * arm.cc (Arm_relobj::Arm_relobj): Initialize new data member output_local_symbol_count_needs_update_. (Arm_relobj::output_local_symbol_count_needs_update, Arm_relobj::set_output_local_symbol_count_needs_update, Arm_relobj::update_output_local_symbol_count): New methods. (Arm_relobj::output_local_symbol_count_needs_update_): New data member. (Arm_exidx_cantunwind::do_fixed_endian_write): Write address of pointed function as in a R_ARM_PREL31 relocation. (Arm_output_section<big_endian>::fix_exidx_coverage): Mark objects for output local symbol count updating. (Target_arm::do_relax): Update output local symbol counts in objects if necessary. * object.h (Sized_relobj::set_output_local_symbol_count): New method.
