From 776489e0a79a14cb3f1138d4e4158ab9a8c7ecf3 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Wed, 16 Jan 2019 21:46:00 -0700 Subject: [PATCH] Remove cleanups from solib-target.c This removes the remaining cleanups from solib-target.c, plus a VEC, by using std::vector and std::unique_ptr. Tested by the buildbot. gdb/ChangeLog 2019-01-17 Tom Tromey * solib-target.c (lm_info_target_p): Remove typedef. Don't declare VEC. (solib_target_parse_libraries): Change return type. (library_list_start_segment, library_list_start_section) (library_list_end_library, library_list_start_library); Update. (solib_target_free_library_list): Remove. (solib_target_parse_libraries): Remove cleanup. Change return type. (solib_target_current_sos): Update. --- gdb/ChangeLog | 12 ++++++++ gdb/solib-target.c | 68 +++++++++++++++------------------------------- 2 files changed, 34 insertions(+), 46 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 0b403c062d4..d05ff7f5910 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,15 @@ +2019-01-17 Tom Tromey + + * solib-target.c (lm_info_target_p): Remove typedef.
