Which ones are incompatible with ARC?
Pass-by-value slices as 2 machine words
64bit pointers are only 40-48 bits, so there's 32bits waste for
an
offset... and if the base pointer is 32byte aligned (all
allocated
memory is aligned), then you can reclaim another 5 bits
there... I
think saving an arg register would probably be worth a shift.
32bit pointers... not so luck :/
video games consoles though have bugger all memory, so heaps of
spare
bits in the pointers! :P
I thought x86_64 pointers are sign extended? or does that just
apply to real memory pointers and not virtual memory pointers?
