Re: [avr-gcc-list] register allocation - something not right

[HutchinsonAndy]

Eric,

my experiments are WITHOUT new-ra for the very reason you state.

My point was that avr register allocation order and/or function call register 
assigment are not sympathetic. Better code is produced using a different 
register allocation order. 

I have yet to try changing the function parameter registers (that is bit more 
involved and I am now sidetracked on code improvements and better cost 
modelling)

best regards
