From 0ad20314f1e11acaeedcb14135b178a5711766f5 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 6 Nov 2020 15:27:37 +0000 Subject: [PATCH] linux-user/sparc: Don't restore %g7 in sparc64_set_context() The kernel does not restore the g7 register in sparc64_set_context(); neither should we. (We still save it in sparc64_get_context().)
