Hi,
I have a question regarding Plus reload situation I ran into in my
port (which was taken from branch 4.6):
I got the following insn: Set d1 (plus r1 -96).
d1 and r1 are 2 registers from different classes.
The reload (which take place at: reload1.c , gen_reload(out = d1, in =
(plus r1 -96))
Hi Ian,
Relevant instruction supported:
add r,r,r
add r,r unsigned
add r,r, signed
add d,d,d
add d,d unsigned
Thanks,
Gal.

oh,
I forgot:
move d,r(d = r)

because it's:add d,d unsigned
we don't have: add d,d signed
and in this case we need: d = r + (-96)
