From d0e66c897f2cdfb0807b76567a17d7811487fac3 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Wed, 5 Apr 2023 13:26:51 -0700 Subject: tcg: Split out tcg_out_ext8u MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We will need a backend interface for performing 8-bit zero-extend. Use it in tcg_reg_alloc_op in the meantime.
