[fpc-devel] thumb2 code generation

Someone pointed me at this page:


And I started adding a device (and perhaps more after that), starting 
with a cortex-m3 though which is thumb/thumb2 only.

Following the instructions on the page work fine:

fpc -Parm -Tembedded -Wplpc2124 tled1.pp

Added my device as well as tried the two other cortex-m3 devices and

fpc -Parm -Tembedded -Wpdevice test.pp

I tried -Parm, -Pthumb, thumb2, cortex-m3 but it just keeps generating 
arm instructions.  I can certainly target an arm processor first but 
would rather try a thumb/thumb2 first.
