From 1c05d53baf1366e1f34a055a7f4ab91c11dc211e Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Mon, 27 May 2024 17:08:46 +0000 Subject: tcg/loongarch64: Support TCG_TYPE_V64 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We can implement this with fld_d, fst_d for load and store, and then use the normal v128 operations in registers. This will improve support for guests which use v64.
