When a shared library appears within --start-group/--end-group ld may only discover a need for loading the library on the second or subsequent pass over archive libraries, as more objects are extracted. ld/ PR 17068 * ldlang.c (load_symbols): Always check flags.reload. (open_input_bfds): Always reload --as-needed shared libraries, not just when rescanning. * ldlang.h (struct lang_input_statement_flags): Update reload comment. * plugin.c (plugin_should_reload): Assume shared library arg. * plugin.h (plugin_should_reload): Update comment. ld/testsuite * ld-elf/pr17068.s: New. * ld-elf/pr17068a.s: New. * ld-elf/pr17068b.s: New. * ld-elf/pr17068c.s: New. * ld-elf/pr17068d.s: New. * ld-elf/pr17068e.s: New. * ld-elf/pr17068ez.s: New. * ld-elf/elf.exp: Run new test.
