Issue

DWARF5 only has Accessibility declarations DW_ACCESS_public, DW_ACCESS_private, and DW_ACCESS_protected. However, FreePascal has a couple more that need to be represented. This is needed so that debuggers can report it back to users and so that ABI checkers like libabigail can detect changes to the API which would then change the ABI of an object.

The full list can be found in the Free Pascal Reference Guide.

Proposal

In Section 2.7:

Add Pascal to the list of languages which have Accessibility of Declarations so that it reads:

Some languages, notably C++, Ada, and Pascal have the concept of the accessibility of an object or of some other program entity. The accessibility specifies which classes of other program objects are permitted access to the object in question.

In Table 2.4 Add three more accessibility codes:

• DW_ACCESS_strict_private
• DW_ACCESS_strict_protected
• DW_ACCESS_published

In Section 8.9 in Table 8.14 Add the following entries to table 8.14:

Accessibility code name	Value
DW_ACCESS_strict_private	TBD
DW_ACCESS_strict_protected	TBD
DW_ACCESS_published	TBD

---

2026-05-10: Added DW_ACCESS_published for completeness.

2026-09-24: Added Pascal to non-normative text listing languages that have accessibility attributes.
