From 53229a7703eeb2bbe101a19a33ef22aaf960c65b Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Sun, 17 Mar 2019 00:27:29 +0000 Subject: tcg: Specify optional vector requirements with a list MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
