By the way, don't spend more time on this right now; I think it's a good
time to decide on a slightly less surprizing interface. Apart from the
whole global-fetching idea, another confusing aspect is that the
rtype_xyz() methods receive s_abc arguments that are not the main thing
they operate on -- they usually operate on variables (v_abc) instead.
So I am thinking about introducing a "high-level operation" concept and
changing the signature of the rtype_xyz() methods:
class __extend__(pairtype(SomeInteger, SomeInteger)):
def rtype_add(_, hlop, llops): # ignore the (s_int1, s_int2) pair
if hlop.s_result.unsigned:
v1, v2 = hlop.convertinputs(Unsigned, Unsigned)
v3 = llops.generate('uint_add', [v1, v2], resulttype=Unsigned)
return v3
else:
v1, v2 = hlop.convertinputs(Signed, Signed)
v3 = llops.generate('int_add', [v1, v2], resulttype=Signed)
return v3
