* trans-stmt.c (gfc_trans_where): Tighten up the dependency
check for calling gfc_trans_where_3.
PR fortran/35743
* trans-stmt.c (gfc_trans_where_2): Set the mask size to zero
if it is calculated to be negative.
PR fortran/35745
* trans-stmt.c (gfc_trans_where_3, gfc_trans_where_assign): Set
ss->where for scalar right hand sides.
* trans-array.c (gfc_add_loop_ss_code): If ss->where is set do
not evaluate scalars outside the loop. Clean up whitespace.
* trans.h : Add a bitfield 'where' to gfc_ss.
PR fortran/36233
* interface.c (compare_actual_formal): Do not check sizes if the
actual is BT_PROCEDURE.
