The get_std_name_hint function so far uses linear search to locate matching entries. After adding more hint entries this might not be appropriate anymore. Therefore this patch also replaces the linear array with a gperf-generated hash table. contrib/ChangeLog * gcc_update (files_and_dependencies): Add rule for gcc/cp/std-name-hint.h. gcc/cp/ChangeLog * Make-lang.in: Add rule to rebuild std-name-hint.h from std-name-hint.gperf. * name-lookup.cc (get_std_name_hint): Remove hints array. Use gperf-generated class std_name_hint_lookup. Include "std-name-hint.h". * std-name-hint.gperf: New file. * std-name-hint.h: New file. Generated from the .gperf file.
