fold (conv (load x)) -> (load (conv*)x).
This allows us to compile this:
void foo(double);
void bar(double *X) { foo(*X); }
To this:
bar:
save -96, %o6, %o6
ld [%i0+4], %o1
ld [%i0], %o0
call foo
nop
restore %g0, %g0, %g0
retl
nop
instead of this:
bar:
save -104, %o6, %o6
ldd [%i0], %f0
std %f0, [%i6+-8]
ld [%i6+-4], %o1
ld [%i6+-8], %o0
call foo
nop
restore %g0, %g0, %g0
retl
nop
on SparcV8.
