From 53c934e9fed9a35542661690e4e71febcbebb539 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Tue, 5 Dec 2017 16:30:25 -0500 Subject: Make tdesc_feature::types an std::vector This patch makes tdesc_feature::types an std::vector of unique_ptr of tdesc_type. This way, we don't need to manually free the objects and the vector in ~tdesc_feature. gdb/ChangeLog: * target-descriptions.c (tdesc_type_p): Remove typedef. (DEF_VEC_P (tdesc_type_p)): Remove. (struct tdesc_feature) : Change type to std::vector. <~tdesc_feature>: Replace with default implementation. : Adjust. (tdesc_named_type): Adjust. (tdesc_create_vector): Adjust. (tdesc_create_struct): Adjust. (tdesc_create_union): Adjust. (tdesc_create_flags): Adjust.
