--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Fixed in GCC 8 by a few patches combined together.
The final result is the following code which deletes the debug_markers:
/* Turn debug markers into notes if the var-tracking pass has not
been invoked. */
if (!flag_var_tracking && MAY_HAVE_DEBUG_MARKER_INSNS)
delete_vta_debug_insns (false);
Which does for each debug_insn (non debug_marker which is handled as a note):
tree decl = INSN_VAR_LOCATION_DECL (insn);
if (TREE_CODE (decl) == LABEL_DECL
&& DECL_NAME (decl)
&& !DECL_RTL_SET_P (decl))
{
PUT_CODE (insn, NOTE);
NOTE_KIND (insn) = NOTE_INSN_DELETED_DEBUG_LABEL;
NOTE_DELETED_LABEL_NAME (insn)
= IDENTIFIER_POINTER (DECL_NAME (decl));
SET_DECL_RTL (decl, insn);
CODE_LABEL_NUMBER (insn) = debug_label_num++;
}
else
delete_insn (insn);
So yes this is fixed and not made latent.
