Right now __moddi3, __umoddi3, __divdi3 and __udivdi3 contain inlined versions of __udivmoddi4. Un-inlining them should save about 5KB in the worst case, 4KB typical. I'm working on it. (These routines implement signed and unsigned 64-bit divides and mods. We use these in dealing with our 64-fixed point frequency representation.)
I just commented out all the lines in print_tune_result, and the size of txrx went down to 21404. Adding -Os gives 20900 (didn't test these builds). Did not test -Os version.
Jeff, which RFX board are you using?
