if (MODE_COMPOSITE_P (outermode)
7347
&& (CONST_SCALAR_INT_P (op)
7348
|| CONST_DOUBLE_AS_FLOAT_P (op)
7349
|| CONST_FIXED_P (op)
7350
|| GET_CODE (op) == CONST_VECTOR))
7351
return NULL_RTX;
it's odd to reject CONST_INT_P but not CONST_DOUBLE-as-int, no? Did you
mean to do
if (MODE_COMPOSITE_P (outermode))
switch (GET_CODE (op))
{
CASE_CONST_ANY:
return NULL_RTX;
default:;
}
? (yeah, CONST_ANY_P is missing it seems)
