[Yonggang Luo]

When I am running QEMU to simulating PowerPC.

And after running the following powerpc code:

00e2b5dc <intUnlock>:
intUnlock():
  e2b5dc: 54 63 04 20 rlwinm r3,r3,0,16,16
  e2b5e0: 7c 80 00 a6 mfmsr r4
  e2b5e4: 7c 83 1b 78 or r3,r4,r3
  e2b5e8: 7c 60 01 24 mtmsr r3
  e2b5ec: 4c 00 01 2c isync
  e2b5f0: 4e 80 00 20 blr

The QEMU are getting stuck and can not running the following instructions,

What I need to do to inspect which instruction are getting stuck and how to fix it?

Any means to debugging that.
