The v7m CONTROL register bit 1 is SPSEL, which indicates the stack being used. We were storing this information not in v7m.control but in the separate v7m.other_sp structure field. Unfortunately, the code handling reads of the CONTROL register didn't take account of this, and so if SPSEL was updated by an exception entry or exit then a subsequent guest read of CONTROL would get the wrong value. Using a separate structure field doesn't really gain us anything in efficiency, so drop this unnecessary complexity in favour of simply storing all the bits in v7m.control. This is a migration compatibility break for M profile CPUs only. Backports commit abc24d86cc0364f402e438fae3acb14289b40734 from qemu |
