Interesting. I don't know if it's due to the nature of my application,
or maybe the relative crappieness of the HiTech 8051 C compiler compared
to IAR, but I've actually been seeing a significant code size
*reduction* for the  same code moving from 8051 to ARM Gnu Gcc. And
that's using pure ARM kode rather than thumb as I have no pressing space
problems at this stage. (pure byte space size reduction, not cheating
comparing number of instruction words).
I did do a number of tests comparing code size for various compilers
early on using demo versions, and IAR was smaller than GCC for the same
code, but this seemed to be largely due to C-library granularity rather
than C->asm efficiency.
