please note that the semihosting support is still incomplete, the code to pass 
the semihosting command line is not in; we discussed a lot about this, I fixed 
it in my fork (GNU ARM Eclipse QEMU), I prepared some patches, but finally they 
were not included.

the code I currently use reflects the latest discussed solution, to add the 
command line to -semihosting-config:

"-semihosting-config [enable=on|off,]target=native|gdb|auto[,cmdline=string]   
semihosting configuration\n",

it is functional, but I'm not sure the usability is ok, requiring to use double 
commas in the command string (if I remember right).



p.s. these days I finally was able to allocate some time to my GNU ARM Eclipse 
QEMU subproject; right now I'm updating the build procedures and then I plan to 
continue work on the generic Cortex-M code.
