[PATCH] Change rs6000_const_f32_to_i32 return type.
The function rs6000_const_f32_to_i32 called REAL_VALUE_TO_TARGET_SINGLE
with a long long type and returns it. This patch changes the type to long
which is the proper type for REAL_VALUE_TO_TARGET_SINGLE.
I have done bootstraps on little endian power9 and big endian power8 systems.
Can I check this into the trunk?
This does not need to go into GCC 11, unless some of the other patches that use
this function are also back ported.
