Subject: [Qemu-devel] [PATCH] target/xtensa: get rid of gen_callw[i]
Date: Mon, 11 Feb 2019 02:06:31 -0800 [thread overview]
Message-ID: <20190211100631.5263-1-jcmvbkbc@gmail.com> (raw)
Merge gen_callwi and gen_callw into their only users, translate_callw
and translate_callxw. Extract jump slot adjustment logic into a separate
function and use it in gen_jumpi and translate_callw.
