From e08bd6c5081f4957ddb60117ac94775dcd618db7 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Sun, 24 May 2020 13:32:25 +0100 Subject: Don't remove C++ aliases from completions if symbol doesn't match completion_list_add_symbol currently tries to remove C++ function aliases from the completions match list even if the symbol passed down wasn't successfully added to the completion list because it didn't match. I.e., we call cp_canonicalize_string_no_typedefs for each and every C++ function in the program, which is useful work. This patch skips that useless work. gdb/ChangeLog: 2020-05-24 Pedro Alves * symtab.c (completion_list_add_name): Return boolean indication of whether the symbol matched. (completion_list_add_symbol): Don't try to remove C++ aliases if the symbol didn't match in the first place. * symtab.h (completion_list_add_name): Return bool. --- gdb/ChangeLog | 8 ++++++++ gdb/symtab.c | 13 ++++++++----- gdb/symtab.h | 5 +++-- 3 files changed, 19 insertions(+), 7 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 35fdc614ee4..9f65e2df970 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,11 @@ +2020-05-24 Pedro Alves + + * symtab.c (completion_list_add_name): Return boolean indication + of whether the symbol matched. + (completion_list_add_symbol): Don't try to remove C++ aliases if + the symbol didn't match in the first place. + * symtab.h (completion_list_add_name): Return bool. + 2020-05-23 Simon Marchi * gdbtypes.h (TYPE_FIELD): Remove.
