Subject: [PATCH v5 06/13] target/mips: Pass instruction opcode to decode_opc_mxu()
Date: Fri, 26 Feb 2021 10:31:03 +0100 [thread overview]
Message-ID: <20210226093111.3865906-7-f4bug@amsat.org> (raw)
In-Reply-To: <20210226093111.3865906-1-f4bug@amsat.org>
In the next commit we'll make decode_opc_mxu() match decodetree
prototype by returning a boolean. First pass ctx->opcode as an
argument.
