X-Received-From: 2607:f8b0:4864:20::643 Subject: [Qemu-devel] [PATCH v3 04/31] tcg: Specify optional vector requirements with a list X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: alex.bennee@linaro.org, david@redhat.com Errors-To: qemu-devel-bounces+patch=linaro.org@nongnu.org Sender: "Qemu-devel" Replace the single opcode in .opc with a null-terminated array in .opt_opc. We still require that all opcodes be used with the same .vece. Validate the contents of this list with CONFIG_DEBUG_TCG. All tcg_gen_*_vec functions will check any list active during .fniv expansion. Swap the active list in and out as we expand other opcodes, or take control away from the front-end function. Convert all existing vector aware front ends.
