Hello qemu developers!

I=B4m using QEMU for some ARM debugging an= d I have som questions regardning the CPSR register. I get the feeling th= at the CPSR condition code bits, representing the results from the ALU, a= re not maintained.

What I want to do is to try to verify QEMU main= tains the CPSR register and if not fix it. However, it is not trivial ide= ntify where the updates should be placed. The relationship between transl= ate.c and op.c is not trival I must say :)

I would be happy I anyo= ne here could give me some pointers on how the updates of the CPSR regist= er is done today and what the strategy is. I guess there are plenty of pe= rformance ideas here as in the rest of qemu.

Does anyone have any = reflection on this topic or can anyone give me some pointers?
