Hi!
Many thanks for this hint. Yes, the code was not ideal in that point.

Hi Sean,
as far as I understand, your tool runs on asm code, i.e. you map short
sequences of asm instructions (which must not contain code labels) to
other instruction sequences.
Right, and it's far from
Hi,
All this talk of super-optimisers, etc. brings this issue I've had,
to the fore again.
Perhaps there are suggestions on how to encourage the compiler to do the
optimisations rather than having to hand-code to get the best result.
Take this code:

Hi All,
Special note to toolchain distribution maintainers, and people who build the
toolchain themselves:
GCC 4.4.0 will soon be released (within days). One of the major new features of
the 4.4 series is a new Integrated Register Allocator (IRA) for all ports,
including the AVR.
While some

I didn't know this...
Is there any workaround
for this? (the datasheet does not say anything...)
Switch to an ATmega1281?
