[Qemu-devel] [PATCH 0/4] Clean up cpu_exec part 2/n

[Paolo Bonzini <pbonzini@redhat.com>]

The management of env->current_tb is quite complicated.  In particular,
a while loop that has it as a test condition is actually executed just
once, and it is cleared long after it has ceased being meaningful.

This patch set straightens things a bit.  Patch 1 clears env->current_tb
when it is not meaningful anymore.  Patch 2 adds assertions that test
the change done in patch 3.  These are then removed in patch 4.

I preferred to be defensive, but I'd understand squashing the three 
patches together as well.

Paolo Bonzini (4):
  clean up env->current_tb
  add assertions about env->current_tb
  change while to if
  remove assertions
