This is not currently supported. See this comment in arm-tdep.c arm_m_exception_cache() /* ARMv8-M Exception and interrupt handling is not considered here. In the ARMv8-M architecture also EXC_RETURN bit S is controlling if the Secure or Non-secure stack was used. To separate Secure and Non-secure stacks, processors that are based on the ARMv8-M architecture support 4 stack pointers: MSP_S, PSP_S, MSP_NS, PSP_NS. In addition, a stack limit feature is provided using stack limit registers (accessible using MSR and MRS instructions) in Privileged level. */ -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
