here is a tree code :
for example output of debug_tree(t1)

<real_type 0xb77a6120 float address-space-1 SF
    size <integer_cst 0xb76d42c0 type <integer_type 0xb76e8060
bit_size_type> constant 32>
    unit size <integer_cst 0xb76d4060 type <integer_type 0xb76e8000
long unsigned int> constant 4>
    align 32 symtab 0 alias set -1 canonical type 0xb77a6120 precision 32>

if I use addr_space_t asl = TYPE_ADDR_SPACE (t1);
I get the address space value in asl.


now, I have another tree code :
 debug_tree(t2)

 <var_decl 0xb781d284 z
    type <real_type 0xb781c120 float address-space-1 SF
        size <integer_cst 0xb774a2c0 constant 32>
        unit size <integer_cst 0xb774a060 constant 4>
        align 32 symtab 0 alias set -1 canonical type 0xb781c120 precision 32>
    used public external common SF defer-output file /tmp/test.c line
21 col 21 size <integer_cst 0xb774a2c0 32> unit size <integer_cst
0xb774a060 4>
    align 32>

if I use addr_space_t asl = TYPE_ADDR_SPACE (t2);
I am not getting the address space value .

so , what is the difference of this two tree?
how do I get the address space value of the 2nd one?
