[Qemu-devel] [PATCH v2] hmp: fix info cpus for sparc targets

[Aurelien Jarno <aurelien@aurel32.net>]

On sparc targets, info cpus returns this kind of output:

| info cpus
| * CPU #0: pc=0x0000000000424d18pc=0x0000000000424d18npc=0x0000000000424d1c thread_id=19460

pc is printed twice, there is no space between pc, pc and npc.

With this patch, pc is not printed anymore when has_npc is set. In addition
the space is printed before pc/nip/npc/PC instead of after the colon so that
multiple prints are possible. This result on the following kind of input on
sparc targets:

| info cpus
| * CPU #0: pc=0x0000000000424d18 npc=0x0000000000424d1c thread_id=19460
