Peter Maydell 76eff04d16 target/arm: Implement SG instruction corner cases ... The common situation of the SG instruction is that it is executed from S&NSC memory by a CPU in NS state. That case is handled by v7m_handle_execute_nsc(). However the instruction also has defined behaviour in a couple of other cases: * SG instruction in NS memory (behaves as a NOP) * SG in S memory but CPU already secure (clears IT bits and does nothing else) * SG instruction in v8M without Security Extension (NOP) These can be implemented in translate.c.
