Hi all,
Could someone help to point out what kind of DWARF info should be generated for
below c++ source? Thanks
```
template<class T>
using ptr = T*;
ptr<int> abc;
```
We declare a template alias here, so we may generate
`DW_TAG_template_type_parameter` like:
```
0x00000057: DW_TAG_base_type
DW_AT_name ("int")
DW_AT_byte_size (0x04)
DW_AT_encoding (DW_ATE_signed)
0x0000005e: DW_TAG_pointer_type
DW_AT_type (0x00000057 "int")
0x00000064: DW_TAG_template_alias
DW_AT_name ("ptr")
DW_AT_type (0x0000005e "int *")
0x00000076: DW_TAG_template_type_parameter
DW_AT_name ("T")
DW_AT_type (0x00000057 "int")
0x0000007e: DW_TAG_variable
DW_AT_name ("abc")
DW_AT_type (0x00000064 "ptr<int>")
```
` DW_TAG_template_type_parameter ` should be for a notation to create a
template base on another template, but as you can see the referred type
0x0000005e is not a template. What kind of DWARF info should we generate here?
We should use ` DW_TAG_typedef` instead of ` DW_TAG_template_type_parameter`
for this special case?
