[PATCH 1/1] target/i386: Generate an illegal opcode exception on cmp instructions with lock prefix

target/i386: As specified by Intel Manual Vol2 3-180, cmp instructions are not allowed to have lock prefix and a `UD` should be raised. Without this patch, s1->T0 will be uninitialized and used in the case OP_CMPL. Signed-off-by: Ziqiao Kong --- target/i386/tcg/translate.c | 11 ++- 1
