is -single-step option supposed to work under qemu-system-sparc? Or is it only for non-pipelined CPUs?
I get pretty strange results: some addresses seem to be executed twice, and then qemu hangs on the last nop: -------------- IN: 0x00000000: b 0xb788 -------------- IN: 0x00000004: rd %psr, %l0 -------------- IN: 0x00000004: rd %psr, %l0 -------------- IN: 0x00000008: nop -------------- IN: 0x00000008: nop -------------- IN: 0x0000000c: nop -------------- IN: 0x0000000c: nop ... skipped ...
