    Hello all, I am currently implementing support for DWARFv5
    DW_AT_alignment attribute
    (<a class="moz-txt-link-freetext" href="http://www.dwarfstd.org/ShowIssue.php?issue=140528.1">http://www.dwarfstd.org/ShowIssue.php?issue=140528.1</a>). I am not
    100% sure which entities we should mark with this attr.<br>
    <br>
    Consider the following C11 code (sample from
    <a class="moz-txt-link-freetext" href="http://en.cppreference.com/w/c/language/_Alignas">http://en.cppreference.com/w/c/language/_Alignas</a>):<br>
    <br>
    // every object of type struct data will be aligned to 128-byte
    boundary <br>
    struct data { <br>
    char x; <br>
    _Alignas(128) char cacheline[128]; // over-aligned array of char, <br>
    // not array of over-aligned chars <br>
    }; <br>
    <br>
    int main(void) <br>
    { <br>
    _Alignas(2048) struct data d; // this instance of data is aligned
    even stricter<br>
    return 0; <br>
    } <br>
    <br>
    What should be marked as DW_AT_alignment? The link above says that
    the attribute can be applied to: <br>
    <pre><big>DW_TAG_array_type, DW_TAG_atomic_type, DW_TAG_base_type, DW_TAG_class_type,
DW_TAG_coarray_type, DW_TAG_const_type, DW_TAG_dynamic_type,
DW_TAG_enumeration_type, DW_TAG_file_type, DW_TAG_interface_type,
DW_TAG_packed_type, DW_TAG_pointer_type, DW_TAG_pointer_to_member_type,
DW_TAG_reference_type, DW_TAG_restrict_type, DW_TAG_rvalue_reference_type,
DW_TAG_set_type, DW_TAG_shared_type, DW_TAG_string_type, DW_TAG_structure_type,
DW_TAG_subprogram, DW_TAG_subrange_type, DW_TAG_subroutine_type,
DW_TAG_thrown_type, DW_TAG_typedef, DW_TAG_union_type, DW_TAG_variable</big></pre>
    <br>
    ┬áHere we have<br>
    <br>
    * DW_TAG_array_type<br>
    * DW_TAG_subrange_type<br>
    * DW_TAG_member <br>
    * DW_TAG_structure_type<br>
    * DW_TAG_basic_type<br>
    * DW_TAG_variable<br>
    <br>
    Currently I mark only variable "d" as aligned, however I am not
    sure, that this is correct? Which of the listed should contain this
    attribute? What do you think?<br>
