From 97ff1478d2783b8c0e71540085aec66a70f2d52b Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Wed, 15 Feb 2023 19:45:11 -1000 Subject: [PATCH] linux-user/sparc: Handle priviledged opcode trap For the most part priviledged opcodes are ifdefed out of the user-only sparc translator, which will then incorrectly produce illegal opcode traps. But there are some code paths that properly raise TT_PRIV_INSN, so we must handle it.
