Subject: [PATCH v2 05/11] gdb: simplify insertion in global_symbol_searcher::add_matching_symbols
Date: Wed, 30 Sep 2026 22:09:22 -0400 [thread overview]
Message-ID: <20261001020952.698419-6-simon.marchi@polymtl.ca> (raw)
In-Reply-To: <20260929194119.155169-1-simon.marchi@efficios.com>
From: Simon Marchi <simon.marchi@efficios.com>
std::set::insert does nothing if an equivalent element is already
in the set, so checking with find first is redundant. Replace find+insert
with emplace.
