[PATCH v3 16/66] target/sparc: Remove DEBUG_UNALIGNED

Posted by Richard Henderson 2 years, 10 months ago

The printf should have been qemu_log_mask, the parameters
themselves no longer compile, and because this is placed
before unwinding the PC is actively wrong.

We get better (and correct) logging on the other side of
raising the exception, in sparc_cpu_do_interrupt.
