From 20c34a9216f41977803659f5bd458618c291d56c Mon Sep 17 00:00:00 2001 From: Brian Cain Date: Sun, 8 Oct 2023 15:09:44 -0700 Subject: [PATCH] target/hexagon: fix some occurrences of -Wshadow=local MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Of the changes in this commit, the changes in `HELPER(commit_hvx_stores)()` are less obvious. They are required because of some macro invocations like SCATTER_OP_WRITE_TO_MEM(). e.g.: In file included from ../target/hexagon/op_helper.c:31: ../target/hexagon/mmvec/macros.h:205:18: error: declaration of ‘i’ shadows a previous local [-Werror=shadow=compatible-local] 205 | for (int i = 0;
