Subject: [PATCH v5 3/4] target/ppc: created tcg-stub.c file
Date: Tue, 25 May 2021 08:53:54 -0300	[thread overview]
Message-ID: <20210525115355.8254-4-bruno.larsen@eldorado.org.br> (raw)
In-Reply-To: <20210525115355.8254-1-bruno.larsen@eldorado.org.br>

Created a file with stubs needed to compile disabling TCG. *_ppc_opcodes
were created to make cpu_init.c have a few less ifdefs, since they are
not needed. softmmu_resize_hpt_* have to be created because the compiler
can't automatically know they aren't used, but they should never be
reached.
