[PATCH] Revise linker plugin API to better preserve link order.
ld/ChangeLog: 2011-03-10 Dave Korn <dave.korn.cygwin@gmail.com> * ldlang.h (lang_input_statement_type): Add new 'claim_archive' flag, wrapping both it and 'claim' flag in #ifdef ENABLE_PLUGINS. * ldmain.c (add_archive_element): Set it if the member is claimed. * ldlang.c (new_afile): Initialise claim_archive and claimed members. (find_replacements_insert_point): New helper function. (lang_process): After adding and opening replacement files passed from plugin, splice them into correct place in statement list and file chains to preserve critical link order. (lang_list_insert_after): New helper function. (lang_list_remove_tail): Likewise.
