Hi This patch does the following: 1. Reference to the global symbol _GLOBAL_OFFSET_TABLE_ is treated as a GOT access to avoid generating unsupported dynamic relocations. The code was borrow from sparc.cc. 2. Treat an input section without any mapping symbols as a data-only section instead of issuing a warning in Arm_relobj::scan_section_for_cortex_a8_stubs. This is consistent with ld. Please see this thread. http://sourceware.org/ml/binutils/2010-02/msg00018.html 3. For EXIDX input section without its link set in the section header, try to discover the linked text section by looking at the REL31 relocation pointing at the first word of the first EXIDX entry. This takes a little bit of code to do but I think it is better than what ld does, which is dropping the section silently without even a warning. Dropping an EXIDX section like this makes the pointed text section not unwindable. -Doug 2010-02-15 Doug Kwan <dougkwan@google.com> * arm.cc (Arm_relobj::find_linked_text_section): New method. (Arm_relobj::make_exidx_input_section): Pass section index of linked text section as a parameter becuase some broken tools may not set the link in section header. (Target_arm::has_got_section): New method. (Target_arm::scan_section_for_cortex_a8_stubs): Treat an input section without any mapping symbol as data only. Remove warning. (Arm_relobj::do_read_synbols): If an EXIDX input section has no link in its section header, try to discover the link by inspecting the REL31 relocation at the beginning of the section. (Target_arm::Scan::check_non_pic): Report name of offending relocation in error message. (Target_arm::Scan::global): Treat any reference to the symbol _GLOBAL_OFFSET_TABLE_ as a GOT access.
