I am one of the developers of the free sdcc compiler and currently working on register and stack allcoation. I see that what I implemented results in better code when compiling my own programs, Contiki, dhrystone, Coremark. But I'd like to know if there is any code for which the new approach performs worse than the on epreviously used in sdcc. And I'd like to know it know, instead of having to wait for bug reports about code size regressions coming in after the next release. Philipp
