Currently the name of a partial DIE is computed eagerly. However, the name is not always needed. This patch changes partial DIEs to compute their name lazily, improving performance by avoiding unnecessary name computations. The run previous to this had times of (see the first patch in the series for an explanation): gdb 1.88 libxul 2.11 Ada 2.60 This patch improves the times to: gdb 1.69 libxul 2.02 Ada 2.52 gdb/ChangeLog 2020-05-27 Tom Tromey <tromey@adacore.com> * dwarf2/read.c (struct partial_die_info) <name>: Declare new method. <canonical_name>: New member. <raw_name>: Rename from "name". (partial_die_info): Initialize canonical_name. (scan_partial_symbols): Check raw_name. (partial_die_parent_scope, partial_die_full_name) (add_partial_symbol, add_partial_subprogram) (add_partial_enumeration, load_partial_dies): Use "name" method. (partial_die_info::name): New method. (partial_die_info::read, guess_partial_die_structure_name) (partial_die_info::fixup): Update. |
