Subject: linux-user/sparc: Handle priviledged opcode trap
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=97ff1478d2783b8c0e71540085aec66a70f2d52b;p=qemu.git

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.
