Minutes, Dwarf 2 Meeting - November 23, 1999
The issues list was posted to the email reflector. Discussion at
the meeting focused on the issues which had written proposals, followed
by other issues.
991021.1 Non-contiguous functions
Jason Merrill will write a proposal, which will include issue
991108.1 (Multiple instruction set support).
991026.3 Duplicate Dwarf data deletion
Champion is now Jason Merrill, who will write a proposal.
991102.1 Modify field definitions for 64-bit arch Adopted
A compiler would need to be told to generate 64-bit Dwarf data.
A smart linker might be able to combine 32-bit Dwarf with 64-bit
Dwarf, but lacking this, all Dwarf files would need to be the
same type. An existing tool which did not handle 64-bit Dwarf
would likely fail upon reading a 64-bit Dwarf file, rather than
provide spurious results.
A number of editorial changes will be required.
991108.1 Multiple instruction set support
Merged into 991021.1
991108.3 Attribute spelling Adopted
Figure 1 should be corrected to use the spelling in the body of the

In Section 6.1.2, insert the word "non-zero" before "length of that
991108.6 DW_OP_add Adopted
Editorial: This should be spelled DW_OP_plus.
991108.7 DW_AT_const_value Adopted
Editorial: The appendix should be corrected to use the spelling
of DW_AT_const_value in the text.
991108.8 Attribute Encodings Withdrawn
Editorial: In Section 7.5.4, the description of "constant" is worded
awkwardly and can be improved.
991108.9 DW_OP_bregx Adopted
Reword description in Section 18.104.22.168 to indicate that the register
number preceeds the offset.
991118.1 Unicode support Adopted
Strings use UTF-8 encoding. A reference to IEC/ISO 10646 should be
