Subject: [PATCH v2 22/29] target/mips: Move Special opcodes to tcg/sysemu/special_helper.c
Date: Mon, 19 Apr 2021 00:50:51 +0200	[thread overview]
Message-ID: <20210418225058.1257014-23-f4bug@amsat.org> (raw)
In-Reply-To: <20210418225058.1257014-1-f4bug@amsat.org>

Move the Special opcodes helpers to tcg/sysemu/special_helper.c.

Since mips_io_recompile_replay_branch() is set as
CPUClass::io_recompile_replay_branch handler in cpu.c,
we need to declare its prototype in "tcg-internal.h".
