It's not clear to me whether I should be passing in UNKNOWN_LOCATION
or input_location to the various functions.
cp_build_unary_op used input_location in various places internally,
so I've passed that in wherever there isn't a better value.
Rather than try to get this right now I'm inclined to
This patch avoids the need for calls to protected_set_expr_location
in the followup patch by adding location_t params to the following
functions:
- build_new
- cp_build_indirect_ref
- cp_build_unary_op
- cp_build_c_cast
- cp_build_modify_expr
It's not clear to me whether I should be pass
