From 3553eadc8cb5f087ea0fb72ebdd1c52264304e0b Mon Sep 17 00:00:00 2001 From: Keith Seitz Date: Wed, 29 Aug 2018 15:12:23 -0700 Subject: [PATCH] Change `label_symbols' to std::vector in linespec.c structures This patch converts linespec.c's linespec.label_symbols member from a VEC to a std::vector. gdb/ChangeLog: * linespec.c (struct linespec) : Change type to std::vector. Update all users. (find_label_symbols_in_block): Change `result' parameter to std::vector. Update all callers. (find_label_symbols): Return std::vector.
