Hi List,

this patchset adds a new -dfilter option and address range matching. With this
execlog can match only a certain range of address for both instruction and
data adresses.

Example usage:

qemu-system-xxx <other options> -d plugin -plugin libexeclog.so,afilter=0x1000-0x2000,dfilter=0x388

This would only log instruction in the address range 0x1000 to 0x2000
and accessing data at address 0x388.

Changes in v2:
- rebased on top of latest master

Sven Schnelle (3):
  plugins/execlog: pass matches array to parse_vaddr_match
  plugins/execlog: add data address match
  plugins/execlog: add address range matching

Yes, i got a 550 mail. But i'll look into the qemu_set_dfilter_ranges()
before resending.
