This is tremendous!

Can somebody check out a few real embedded application? So we can see if there is any I/O hiccups and get a feel for code improvement? Something very "char/byte" orientated plus some floating point?? oh yes - it should be run and see if it works rather than just compile/simulate.

I have found no issues but I have other optimisation in my setup that now prevent a true comparision.

Hi,

Meanwhile I have run the testsuite (using the simulavr simulator) with and without modes defined tieable. When modes are declared to be tieable, 3 failures disappear:
