Subject: [Tarantool-patches] [PATCH luajit v3 1/5] core: add const to lj_debug_line proto parameter
Date: Fri, 20 Aug 2021 14:05:42 +0700
Message-ID: <20210820070546.115293-2-m.shishatskiy@tarantool.org> (raw)
In-Reply-To: <20210820070546.115293-1-m.shishatskiy@tarantool.org>

As `lj_debug_line` function does not change data under `pt`
pointer argument neither by designation nor in fact, it is
more correct to mark this pointer const.
