it looks like we have a bug here but I am not sure.
Currently<br class="gmail_msg">
if we have two similar types with implicit_const attributes
and<br class="gmail_msg">
different values we end up with only one abbrev in
.debug_abbrev<br class="gmail_msg">
section. For example consider two structures: S1 with
implicit_const<br class="gmail_msg">
attribute ATTR and value VAL1 and S2 with implicit_const
ATTR and value<br class="gmail_msg">
VAL2. The .debug_abbrev section will contain only 1 related
record:<br class="gmail_msg">
<br class="gmail_msg">
[N] DW_TAG_structure_type DW_CHILDREN_yes<br
class="gmail_msg">
DW_AT_ATTR DW_FORM_implicit_const VAL1<br
class="gmail_msg">
// ....<br class="gmail_msg">
<br class="gmail_msg">
However it looks like we need to have two different
abbreviations here:<br class="gmail_msg">
<br class="gmail_msg">
[N] DW_TAG_structure_type DW_CHILDREN_yes<br
class="gmail_msg">
DW_AT_ATTR DW_FORM_implicit_const VAL1<br

// ....<br class="gmail_msg">
<br class="gmail_msg">
[M] DW_TAG_structure_type DW_CHILDREN_yes<br
class="gmail_msg">
DW_AT_ATTR DW_FORM_implicit_const VAL2<br
class="gmail_msg">
// ....<br class="gmail_msg">
<br class="gmail_msg">
What do you think? If it is a bug I will fix it (as I was
the one who<br class="gmail_msg">
added support for DW_FORM_implicit_const).<br
