--- Comment #1 from Hannes Domani <ssbssa at sourceware dot org> ---
Both A::val_ and A::val2_ have basically the same debug information, so the=
re
is now way that gdb could know that only A::val_ was originally a T:

        .uleb128 0x7     # (DIE (0xf7) DW_TAG_member)
        .ascii "val_\0"  # DW_AT_name
        .byte   0x1      # DW_AT_decl_file (gdb-20540.cpp)
        .byte   0x7      # DW_AT_decl_line
        .byte   0x5      # DW_AT_decl_column
        .long   0x12c    # DW_AT_type
        .byte   0        # DW_AT_data_member_location
        .uleb128 0x7     # (DIE (0x105) DW_TAG_member)
        .ascii "val2_\0"         # DW_AT_name
        .byte   0x1      # DW_AT_decl_file (gdb-20540.cpp)
        .byte   0x8      # DW_AT_decl_line
        .byte   0x7      # DW_AT_decl_column
        .long   0x12c    # DW_AT_type
        .byte   0x4      # DW_AT_data_member_location

Both have DW_AT_type 0x12c, which is int in this case:

        .uleb128 0xb     # (DIE (0x12c) DW_TAG_base_type)
        .byte   0x4      # DW_AT_byte_size
        .byte   0x5      # DW_AT_encoding
        .ascii "int\0"   # DW_AT_name

And it's the same for A::get and A::add.
