When searching static symbols, gdb would search over all expanded symtabs of all objfiles, and if that fails only then would it search all partial/gdb_index tables of all objfiles. This means that the user could get a random instance of the symbol depending on what symtabs have been previously expanded. Now the search is consistent, searching each objfile completely before proceeding to the next one. gdb/ChangeLog: PR symtab/17564 * symtab.c (lookup_symbol_in_all_objfiles): Delete. (lookup_static_symbol): Move definition to new location and rewrite. (lookup_symbol_in_objfile): New function. (lookup_symbol_global_iterator_cb): Call it. gdb/testsuite/ChangeLog: PR symtab/17564 * gdb.base/symtab-search-order.exp: New file. * gdb.base/symtab-search-order.c: New file. * gdb.base/symtab-search-order-1.c: New file. * gdb.base/symtab-search-order-shlib-1.c: New file.
