Hi,

I updated the arm backend in the dynrec.

The most important change is the option to use armv7 instructions. A version using armv7 instructions is 50% faster than a version without this update - using doom2 timedemo (75% faster in a benchmark without graphics output).

Diff file of trunk against revision 3778 is in the attachement.

Changed files:
src/cpu/core_dynrec.cpp
src/cpu/core_dynrec/Makefile.am
src/cpu/core_dynrec/risc_armv4le.h
src/cpu/core_dynrec/risc_armv4le-o3.h
