Having both of these is probably not useful. Bernd pointed
out that a 17-bit constant would be more

If you're using a bit to decide between these two, a better encoding
would be to just support a sing

Hard to say. It really depends on the kind of constants you expect your
programs to use. It's generally a good idea to have an efficient way to
load small constants which many progr
Hello all,
I am trying to do a port on GCC 4.5. The target has a memory
resolution of 32bits i.e. char is 32bits in the target (addr 0 selects
1st 32bit and addr 1 selects 2nd 32bit). It has only word (32bit)
access.
In terms of address resolution this target is similar to c4x which
became obsole
