Subject: [Tarantool-patches] [PATCH luajit 5/7] memprof: add profile common section
Date: Wed,  8 Sep 2021 20:50:48 +0300
Message-ID: <e5d6b75269b5d38b754f009fad781d59d061df87.1631122521.git.m.kokryashkin@tarantool.org> (raw)
In-Reply-To: <cover.1631122521.git.m.kokryashkin@tarantool.org>

A Lua API for sysprof needs to be introduced, but sysprof's C API is quite
similar with memprof's. Considering this, there are some structures and
functions that should be common between memprof's and sysprof's
implementations of Lua API to avoid duplication.
