Subject: [Tarantool-patches] [PATCH luajit 0/3] Generation of immediates and TBAR fusion
Date: Thu, 24 Jul 2025 12:03:57 +0300 [thread overview]
Message-ID: <cover.1753344905.git.skaplun@tarantool.org> (raw)
The first 2 patches are required to avoid conflicts with the last one
patch. The last patch fixes incorrect fusion of instructions across IR,
which leads to incorrect label target.
