typedef struct
{
int i;
} AAA;
typedef struct BBB
{
int i;
} BBB;
int main(void) {
BBB bb;
AAA aa;
return 0;
}
produces
<3><a2>: Abbrev Number: 9 (DW_TAG_variable)
<a3> DW_AT_name : bb
<a6> DW_AT_decl_file : 1
<a7> DW_AT_decl_line : 13
<a8> DW_AT_type : <0x66>
<ac> DW_AT_location : 2 byte block: 91 60 (DW_OP_fbreg: -32)

<b5> DW_AT_type : <0x2d>

where
<1><66>: Abbrev Number: 6 (DW_TAG_typedef)

<31> DW_AT_name : AAA
<35> DW_AT_sibling : <0x46>
(bad)
This seems to be because in gen_type_die_with_usage we arrive with a
type that has a non-typedef type-decl as its name.
