missing instructions in "Dual-Issue Scheduling Rules"

[Gravis]

the Dual-Issue Scheduling Rules does not list iadd | isub | imul | imadd | imsub on the categorized table of instructions. while i would assume they are IALU instructions, they are conditional based on the ARITHMODE flag. so where do these belong on the list of instruction types?

Have a look at:

Though aolofsson does not give a concrete answer, it seems likely that secondary IALU opcodes behave just like FPU opcodes do.

so... any new info here? i really do want to know about the penalty information in regards to the secondary IALU. at the very least, i hope they are well documented in the next version of the epiphany architecture reference... and that it comes out soon.

Sweet! Now I don't have to worry about converting between ints and floats.
