I have created some units for nxp cortex-m0 cpu's and have integrated 
them into the arm-embedded rtl

but they fail to assemble, seems that the generated assembler code is 
not cortex-m0 compatible !!??!!:

make clean buildbase CROSSINSTALL=1 OS_TARGET=embedded CPU_TARGET=arm 
SUBARCH=armv6m CROSSOPT="-godwarfsets -gw2 -O-" 
BINUTILSPREFIX=arm-none-eabi-
