Minutes, October 3, 2000
Eager met with Andrew Salem, President of the IEEE Industry and
Standards Organization to discuss participation under the ISTO
Industry organizations under ISTO are called "forums". There are
currently several standard efforts under the ISTO umbrella: Nexus
5001 (formerly Global Embedded Processor Debug Interface Standard
Consortium), PWG (Printer Working Group), Broadband Wireless Internet
Forum (BWIF), and several others. The standards which these bodies
produce are not IEEE standards, but standards of there respective
Documents produced by the forums may, at the option of the forum,
be freely distributed. IEEE-ISTO will manage billing members,
archiving and publication of documents, and can provide a range of
Salem will send materials necessary to form a Dwarf2 forum.
The existing document contains a copyright and disclaimer by Unix
International. No one appears to have acquired any of the rights
to this copyright when Unix International dissolved.
Changes to the copyright were discussed at the meeting. Suggestions
included: remove all prior copyright statements; mention Unix
International is defunct; say the document is in the public domain.
Final decision was to remove the disclaimer by Unix International
from the copyright page and indicate that Unix International is defunct.
The copyright statement was left as is. Additional changes may be
needed when moved under IEEE-ISTO.
We planned discussion for future meetings:
10/17 -- void * (Brender)
Fortran modules - proposal 000929.1 (Brender)
trampoline/thunk/interlude code (Brender)
10/31 -- factored offset (Anderson)
11/14 -- versioning (Eager)
java support (Burton)
data compression (Dehnert/Anderson)
multiple instruction sets (Eager)
000914.1 Discontinuous Ranges
This proposal is to provide support for objects (compilation
unit, subprogram, etc.) which are not contiguous in memory. Entries
consist of a starting address and length for each segment of the block.
There does not appear to be any conflict with the .debug_aranges
contents, and, since DW_AT_low_pc and DW_AT_high_pc are not currently
generated for discontinuous ranges, there appear to be little or no
problem with upward compatibility. The proposal was accepted with a
few modifications: the range entries are unsorted and contained in
a new section: .debug_ranges. Any object with a discontinuous
range must specify DW_AT_entry_pc.
000915.1 Source File
This proposal, to define that DW_MACINFO_start_file
contains a zero
in the line number, was accepted.
