Thanks but ppc target doesn't work here with gcc 4.3 trunk , i686-linux :

gcc -mtune=native -march=native -O2 -pipe -fomit-frame-pointer 
-Wstrict-overflow -Wall -O2 -g -fno-strict-aliasing -fomit-frame-pointer -I. 
-I..

../dyngen -g -o gen-op.h op.o
dyngen: ret or jmp expected at the end of op_divw

This is for ppc-linux-user .

Also arm-linux-user is broken :
