Appendix A GDB Currently available observers

********************************************

A.1 Implementation rationale

============================

An "observer" is an entity which is interested in being notified when

GDB reaches certain states, or certain events occur in GDB.  The entity

being observed is called the "subject".  To receive notifications, the

observer attaches a callback to the subject.  One subject can have

several observers.

   `observer.c' implements an internal generic low-level event

notification mechanism.  This generic event notification mechanism is

then re-used to implement the exported high-level notification

management routines for all possible notifications.

   The current implementation of the generic observer provides support

for contextual data.  This contextual data is given to the subject when

attaching the callback.  In return, the subject will provide this

contextual data back to the observer as a parameter of the callback.

   Note that the current support for the contextual data is only

partial, as it lacks a mechanism that would deallocate this data when

the callback is detached.  This is not a problem so far, as this

contextual data is only used internally to hold a function pointer.

Later on, if a certain observer needs to provide support for user-level

contextual data, then the generic notification mechanism will need to be

enhanced to allow the observer to provide a routine to deallocate the

data when attaching the callback.

   The observer implementation is also currently not reentrant.  In

particular, it is therefore not possible to call the attach or detach

routines during a notification.

A.2 Debugging

=============

Observer notifications can be traced using the command `set debug

observer 1' (*note Optional messages about internal happenings:

(gdb)Debugging Output.).

A.3 `normal_stop' Notifications

===============================

GDB notifies all `normal_stop' observers when the inferior execution

has just stopped, the associated messages and annotations have been

printed, and the control is about to be returned to the user.

   Note that the `normal_stop' notification is not emitted when the

execution stops due to a breakpoint, and this breakpoint has a

condition that is not met.  If the breakpoint has any associated

commands list, the commands are executed after the notification is

emitted.

   The following interfaces are available to manage observers:

 -- Function: extern struct observer *observer_attach_EVENT

          (observer_EVENT_ftype *F)

     Using the function F, create an observer that is notified when

     ever EVENT occurs, return the observer.

 -- Function: extern void observer_detach_EVENT (struct observer

          *OBSERVER);

     Remove OBSERVER from the list of observers to be notified when

     EVENT occurs.

 -- Function: extern void observer_notify_EVENT (void);

     Send a notification to all EVENT observers.

   The following observable events are defined:

 -- Function: void normal_stop (struct bpstats *BS, int PRINT_FRAME)

     The inferior has stopped for real.  The  BS argument describes the

     breakpoints were are stopped at, if any.  Second argument

     PRINT_FRAME non-zero means display the location where the inferior

     has stopped.

 -- Function: void target_changed (struct target_ops *TARGET)

     The target's register contents have changed.

 -- Function: void executable_changed (void)

     The executable being debugged by GDB has changed: The user decided

     to debug a different program, or the program he was debugging has

     been modified since being loaded by the debugger (by being

     recompiled, for instance).

 -- Function: void inferior_created (struct target_ops *OBJFILE, int

          FROM_TTY)

     GDB has just connected to an inferior.  For `run', GDB calls this

     observer while the inferior is still stopped at the entry-point

     instruction.  For `attach' and `core', GDB calls this observer

     immediately after connecting to the inferior, and before any

     information on the inferior has been printed.

 -- Function: void solib_loaded (struct so_list *SOLIB)

     The shared library specified by SOLIB has been loaded.  Note that

     when GDB calls this observer, the library's symbols probably

     haven't been loaded yet.

 -- Function: void solib_unloaded (struct so_list *SOLIB)

     The shared library specified by SOLIB has been unloaded.  Note

     that when GDB calls this observer, the library's symbols have not

     been unloaded yet, and thus are still available.

 -- Function: void new_objfile (struct objfile *OBJFILE)

     The symbol file specified by OBJFILE has been loaded.  Called with

     OBJFILE equal to `NULL' to indicate previously loaded symbol table

     data has now been invalidated.

 -- Function: void new_thread (struct thread_info *T)

     The thread specified by T has been created.

 -- Function: void thread_exit (struct thread_info *T, int SILENT)

     The thread specified by T has exited.  The SILENT argument

     indicates that GDB is removing the thread from its tables without

     wanting to notify the user about it.

 -- Function: void thread_stop_requested (ptid_t PTID)

     An explicit stop request was issued to PTID.  If PTID equals

     MINUS_ONE_PTID, the request applied to all threads.  If

     `ptid_is_pid(ptid)' returns true, the request applied to all

     threads of the process pointed at by PTID.  Otherwise, the request

     applied to the single thread pointed at by PTID.

 -- Function: void target_resumed (ptid_t PTID)

     The target was resumed.  The PTID parameter specifies which thread

     was resume, and may be RESUME_ALL if all threads are resumed.

 -- Function: void about_to_proceed (void)

     The target is about to be proceeded.

 -- Function: void breakpoint_created (int BPNUM)

     A new breakpoint has been created.  The argument BPNUM is the

     number of the newly-created breakpoint.

 -- Function: void breakpoint_deleted (int BPNUM)

     A breakpoint has been destroyed.  The argument BPNUM is the number

     of the newly-destroyed breakpoint.

 -- Function: void breakpoint_modified (int BPNUM)

     A breakpoint has been modified in some way.  The argument BPNUM is

     the number of the modified breakpoint.

 -- Function: void tracepoint_created (int TPNUM)

     A new tracepoint has been created.  The argument TPNUM is the

     number of the newly-created tracepoint.

 -- Function: void tracepoint_deleted (int TPNUM)

     A tracepoint has been destroyed.  The argument TPNUM is the number

     of the newly-destroyed tracepoint.

 -- Function: void tracepoint_modified (int TPNUM)

     A tracepoint has been modified in some way.  The argument TPNUM is

     the number of the modified tracepoint.

 -- Function: void architecture_changed (struct gdbarch *NEWARCH)

     The current architecture has changed.  The argument NEWARCH is a

     pointer to the new architecture.

 -- Function: void thread_ptid_changed (ptid_t OLD_PTID, ptid_t

          NEW_PTID)

     The thread's ptid has changed.  The OLD_PTID parameter specifies

     the old value, and NEW_PTID specifies the new value.

 -- Function: void inferior_appeared (int PID)

     GDB has attached to a new inferior identified by PID.

 -- Function: void inferior_exit (int PID)

     Either GDB detached from the inferior, or the inferior exited.

     The argument PID identifies the inferior.

 -- Function: void memory_changed (CORE_ADDR ADDR, int LEN, const

          bfd_byte *DATA)

     Bytes from DATA to DATA + LEN have been written to the current

     inferior at ADDR.

 -- Function: void test_notification (int SOMEARG)

     This observer is used for internal testing.  Do not use.  See

     testsuite/gdb.gdb/observer.exp.

Appendix B GNU Free Documentation License

*****************************************

                      Version 1.2, November 2002

     Copyright (C) 2000,2001,2002 Free Software Foundation, Inc.

     51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA.

     Everyone is permitted to copy and distribute verbatim copies

     of this license document, but changing it is not allowed.

  0. PREAMBLE

     The purpose of this License is to make a manual, textbook, or other

     functional and useful document "free" in the sense of freedom: to

     assure everyone the effective freedom to copy and redistribute it,

     with or without modifying it, either commercially or

     noncommercially.  Secondarily, this License preserves for the

     author and publisher a way to get credit for their work, while not

     being considered responsible for modifications made by others.

     This License is a kind of "copyleft", which means that derivative

     works of the document must themselves be free in the same sense.

     It complements the GNU General Public License, which is a copyleft

     license designed for free software.

     We have designed this License in order to use it for manuals for

     free software, because free software needs free documentation: a

     free program should come with manuals providing the same freedoms

     that the software does.  But this License is not limited to

     software manuals; it can be used for any textual work, regardless

     of subject matter or whether it is published as a printed book.

     We recommend this License principally for works whose purpose is

     instruction or reference.

  1. APPLICABILITY AND DEFINITIONS

     This License applies to any manual or other work, in any medium,

     that contains a notice placed by the copyright holder saying it

     can be distributed under the terms of this License.  Such a notice

     grants a world-wide, royalty-free license, unlimited in duration,

     to use that work under the conditions stated herein.  The

     "Document", below, refers to any such manual or work.  Any member

     of the public is a licensee, and is addressed as "you".  You

     accept the license if you copy, modify or distribute the work in a

     way requiring permission under copyright law.

     A "Modified Version" of the Document means any work containing the

     Document or a portion of it, either copied verbatim, or with

     modifications and/or translated into another language.

     A "Secondary Section" is a named appendix or a front-matter section

     of the Document that deals exclusively with the relationship of the

     publishers or authors of the Document to the Document's overall

     subject (or to related matters) and contains nothing that could

     fall directly within that overall subject.  (Thus, if the Document

     is in part a textbook of mathematics, a Secondary Section may not

     explain any mathematics.)  The relationship could be a matter of

     historical connection with the subject or with related matters, or

     of legal, commercial, philosophical, ethical or political position

     regarding them.

     The "Invariant Sections" are certain Secondary Sections whose

     titles are designated, as being those of Invariant Sections, in

     the notice that says that the Document is released under this

     License.  If a section does not fit the above definition of

     Secondary then it is not allowed to be designated as Invariant.

     The Document may contain zero Invariant Sections.  If the Document

     does not identify any Invariant Sections then there are none.

     The "Cover Texts" are certain short passages of text that are

     listed, as Front-Cover Texts or Back-Cover Texts, in the notice

     that says that the Document is released under this License.  A

     Front-Cover Text may be at most 5 words, and a Back-Cover Text may

     be at most 25 words.

     A "Transparent" copy of the Document means a machine-readable copy,

     represented in a format whose specification is available to the

     general public, that is suitable for revising the document

     straightforwardly with generic text editors or (for images

     composed of pixels) generic paint programs or (for drawings) some

     widely available drawing editor, and that is suitable for input to

     text formatters or for automatic translation to a variety of

     formats suitable for input to text formatters.  A copy made in an

     otherwise Transparent file format whose markup, or absence of

     markup, has been arranged to thwart or discourage subsequent

     modification by readers is not Transparent.  An image format is

     not Transparent if used for any substantial amount of text.  A

     copy that is not "Transparent" is called "Opaque".

     Examples of suitable formats for Transparent copies include plain

     ASCII without markup, Texinfo input format, LaTeX input format,

     SGML or XML using a publicly available DTD, and

     standard-conforming simple HTML, PostScript or PDF designed for

     human modification.  Examples of transparent image formats include

     PNG, XCF and JPG.  Opaque formats include proprietary formats that

     can be read and edited only by proprietary word processors, SGML or

     XML for which the DTD and/or processing tools are not generally

     available, and the machine-generated HTML, PostScript or PDF

     produced by some word processors for output purposes only.

     The "Title Page" means, for a printed book, the title page itself,

     plus such following pages as are needed to hold, legibly, the

     material this License requires to appear in the title page.  For

     works in formats which do not have any title page as such, "Title

     Page" means the text near the most prominent appearance of the

     work's title, preceding the beginning of the body of the text.

     A section "Entitled XYZ" means a named subunit of the Document

     whose title either is precisely XYZ or contains XYZ in parentheses

     following text that translates XYZ in another language.  (Here XYZ

     stands for a specific section name mentioned below, such as

     "Acknowledgements", "Dedications", "Endorsements", or "History".)

     To "Preserve the Title" of such a section when you modify the

     Document means that it remains a section "Entitled XYZ" according

     to this definition.

     The Document may include Warranty Disclaimers next to the notice

     which states that this License applies to the Document.  These

     Warranty Disclaimers are considered to be included by reference in

     this License, but only as regards disclaiming warranties: any other

     implication that these Warranty Disclaimers may have is void and

     has no effect on the meaning of this License.

  2. VERBATIM COPYING

     You may copy and distribute the Document in any medium, either

     commercially or noncommercially, provided that this License, the

     copyright notices, and the license notice saying this License

     applies to the Document are reproduced in all copies, and that you

     add no other conditions whatsoever to those of this License.  You

     may not use technical measures to obstruct or control the reading

     or further copying of the copies you make or distribute.  However,

     you may accept compensation in exchange for copies.  If you

     distribute a large enough number of copies you must also follow

     the conditions in section 3.

     You may also lend copies, under the same conditions stated above,

     and you may publicly display copies.

  3. COPYING IN QUANTITY

     If you publish printed copies (or copies in media that commonly

     have printed covers) of the Document, numbering more than 100, and

     the Document's license notice requires Cover Texts, you must

     enclose the copies in covers that carry, clearly and legibly, all

     these Cover Texts: Front-Cover Texts on the front cover, and

     Back-Cover Texts on the back cover.  Both covers must also clearly

     and legibly identify you as the publisher of these copies.  The

     front cover must present the full title with all words of the

     title equally prominent and visible.  You may add other material

     on the covers in addition.  Copying with changes limited to the

     covers, as long as they preserve the title of the Document and

     satisfy these conditions, can be treated as verbatim copying in

     other respects.

     If the required texts for either cover are too voluminous to fit

     legibly, you should put the first ones listed (as many as fit

     reasonably) on the actual cover, and continue the rest onto

     adjacent pages.

     If you publish or distribute Opaque copies of the Document

     numbering more than 100, you must either include a

     machine-readable Transparent copy along with each Opaque copy, or

     state in or with each Opaque copy a computer-network location from

     which the general network-using public has access to download

     using public-standard network protocols a complete Transparent

     copy of the Document, free of added material.  If you use the

     latter option, you must take reasonably prudent steps, when you

     begin distribution of Opaque copies in quantity, to ensure that

     this Transparent copy will remain thus accessible at the stated

     location until at least one year after the last time you

     distribute an Opaque copy (directly or through your agents or

     retailers) of that edition to the public.

     It is requested, but not required, that you contact the authors of

     the Document well before redistributing any large number of

     copies, to give them a chance to provide you with an updated

     version of the Document.

  4. MODIFICATIONS

     You may copy and distribute a Modified Version of the Document

     under the conditions of sections 2 and 3 above, provided that you

     release the Modified Version under precisely this License, with

     the Modified Version filling the role of the Document, thus

     licensing distribution and modification of the Modified Version to

     whoever possesses a copy of it.  In addition, you must do these

     things in the Modified Version:

       A. Use in the Title Page (and on the covers, if any) a title

          distinct from that of the Document, and from those of

          previous versions (which should, if there were any, be listed

          in the History section of the Document).  You may use the

          same title as a previous version if the original publisher of

          that version gives permission.

       B. List on the Title Page, as authors, one or more persons or

          entities responsible for authorship of the modifications in

          the Modified Version, together with at least five of the

          principal authors of the Document (all of its principal

          authors, if it has fewer than five), unless they release you

          from this requirement.

       C. State on the Title page the name of the publisher of the

          Modified Version, as the publisher.

       D. Preserve all the copyright notices of the Document.

       E. Add an appropriate copyright notice for your modifications

          adjacent to the other copyright notices.

       F. Include, immediately after the copyright notices, a license

          notice giving the public permission to use the Modified

          Version under the terms of this License, in the form shown in

          the Addendum below.

       G. Preserve in that license notice the full lists of Invariant

          Sections and required Cover Texts given in the Document's

          license notice.

       H. Include an unaltered copy of this License.

       I. Preserve the section Entitled "History", Preserve its Title,

          and add to it an item stating at least the title, year, new

          authors, and publisher of the Modified Version as given on

          the Title Page.  If there is no section Entitled "History" in

          the Document, create one stating the title, year, authors,

          and publisher of the Document as given on its Title Page,

          then add an item describing the Modified Version as stated in

          the previous sentence.

       J. Preserve the network location, if any, given in the Document

          for public access to a Transparent copy of the Document, and

          likewise the network locations given in the Document for

          previous versions it was based on.  These may be placed in

          the "History" section.  You may omit a network location for a

          work that was published at least four years before the

          Document itself, or if the original publisher of the version

          it refers to gives permission.

       K. For any section Entitled "Acknowledgements" or "Dedications",

          Preserve the Title of the section, and preserve in the

          section all the substance and tone of each of the contributor

          acknowledgements and/or dedications given therein.

       L. Preserve all the Invariant Sections of the Document,

          unaltered in their text and in their titles.  Section numbers

          or the equivalent are not considered part of the section

          titles.

       M. Delete any section Entitled "Endorsements".  Such a section

          may not be included in the Modified Version.

       N. Do not retitle any existing section to be Entitled

          "Endorsements" or to conflict in title with any Invariant

          Section.

       O. Preserve any Warranty Disclaimers.

     If the Modified Version includes new front-matter sections or

     appendices that qualify as Secondary Sections and contain no

     material copied from the Document, you may at your option

     designate some or all of these sections as invariant.  To do this,

     add their titles to the list of Invariant Sections in the Modified

     Version's license notice.  These titles must be distinct from any

     other section titles.

     You may add a section Entitled "Endorsements", provided it contains

     nothing but endorsements of your Modified Version by various

     parties--for example, statements of peer review or that the text

     has been approved by an organization as the authoritative

     definition of a standard.

     You may add a passage of up to five words as a Front-Cover Text,

     and a passage of up to 25 words as a Back-Cover Text, to the end

     of the list of Cover Texts in the Modified Version.  Only one

     passage of Front-Cover Text and one of Back-Cover Text may be

     added by (or through arrangements made by) any one entity.  If the

     Document already includes a cover text for the same cover,

     previously added by you or by arrangement made by the same entity

     you are acting on behalf of, you may not add another; but you may

     replace the old one, on explicit permission from the previous

     publisher that added the old one.

     The author(s) and publisher(s) of the Document do not by this

     License give permission to use their names for publicity for or to

     assert or imply endorsement of any Modified Version.

  5. COMBINING DOCUMENTS

     You may combine the Document with other documents released under

     this License, under the terms defined in section 4 above for

     modified versions, provided that you include in the combination

     all of the Invariant Sections of all of the original documents,

     unmodified, and list them all as Invariant Sections of your

     combined work in its license notice, and that you preserve all

     their Warranty Disclaimers.

     The combined work need only contain one copy of this License, and

     multiple identical Invariant Sections may be replaced with a single

     copy.  If there are multiple Invariant Sections with the same name

     but different contents, make the title of each such section unique

     by adding at the end of it, in parentheses, the name of the

     original author or publisher of that section if known, or else a

     unique number.  Make the same adjustment to the section titles in

     the list of Invariant Sections in the license notice of the

     combined work.

     In the combination, you must combine any sections Entitled

     "History" in the various original documents, forming one section

     Entitled "History"; likewise combine any sections Entitled

     "Acknowledgements", and any sections Entitled "Dedications".  You

     must delete all sections Entitled "Endorsements."

  6. COLLECTIONS OF DOCUMENTS

     You may make a collection consisting of the Document and other

     documents released under this License, and replace the individual

     copies of this License in the various documents with a single copy

     that is included in the collection, provided that you follow the

     rules of this License for verbatim copying of each of the

     documents in all other respects.

     You may extract a single document from such a collection, and

     distribute it individually under this License, provided you insert

     a copy of this License into the extracted document, and follow

     this License in all other respects regarding verbatim copying of

     that document.

  7. AGGREGATION WITH INDEPENDENT WORKS

     A compilation of the Document or its derivatives with other

     separate and independent documents or works, in or on a volume of

     a storage or distribution medium, is called an "aggregate" if the

     copyright resulting from the compilation is not used to limit the

     legal rights of the compilation's users beyond what the individual

     works permit.  When the Document is included in an aggregate, this

     License does not apply to the other works in the aggregate which

     are not themselves derivative works of the Document.

     If the Cover Text requirement of section 3 is applicable to these

     copies of the Document, then if the Document is less than one half

     of the entire aggregate, the Document's Cover Texts may be placed

     on covers that bracket the Document within the aggregate, or the

     electronic equivalent of covers if the Document is in electronic

     form.  Otherwise they must appear on printed covers that bracket

     the whole aggregate.

  8. TRANSLATION

     Translation is considered a kind of modification, so you may

     distribute translations of the Document under the terms of section

     4.  Replacing Invariant Sections with translations requires special

     permission from their copyright holders, but you may include

     translations of some or all Invariant Sections in addition to the

     original versions of these Invariant Sections.  You may include a

     translation of this License, and all the license notices in the

     Document, and any Warranty Disclaimers, provided that you also

     include the original English version of this License and the

     original versions of those notices and disclaimers.  In case of a

     disagreement between the translation and the original version of

     this License or a notice or disclaimer, the original version will

     prevail.

     If a section in the Document is Entitled "Acknowledgements",

     "Dedications", or "History", the requirement (section 4) to

     Preserve its Title (section 1) will typically require changing the

     actual title.

  9. TERMINATION

     You may not copy, modify, sublicense, or distribute the Document

     except as expressly provided for under this License.  Any other

     attempt to copy, modify, sublicense or distribute the Document is

     void, and will automatically terminate your rights under this

     License.  However, parties who have received copies, or rights,

     from you under this License will not have their licenses

     terminated so long as such parties remain in full compliance.

 10. FUTURE REVISIONS OF THIS LICENSE

     The Free Software Foundation may publish new, revised versions of

     the GNU Free Documentation License from time to time.  Such new

     versions will be similar in spirit to the present version, but may

     differ in detail to address new problems or concerns.  See

     `http://www.gnu.org/copyleft/'.

     Each version of the License is given a distinguishing version

     number.  If the Document specifies that a particular numbered

     version of this License "or any later version" applies to it, you

     have the option of following the terms and conditions either of

     that specified version or of any later version that has been

     published (not as a draft) by the Free Software Foundation.  If

     the Document does not specify a version number of this License,

     you may choose any version ever published (not as a draft) by the

     Free Software Foundation.

B.1 ADDENDUM: How to use this License for your documents

========================================================

To use this License in a document you have written, include a copy of

the License in the document and put the following copyright and license

notices just after the title page:

       Copyright (C)  YEAR  YOUR NAME.

       Permission is granted to copy, distribute and/or modify this document

       under the terms of the GNU Free Documentation License, Version 1.2

       or any later version published by the Free Software Foundation;

       with no Invariant Sections, no Front-Cover Texts, and no Back-Cover

       Texts.  A copy of the license is included in the section entitled ``GNU

       Free Documentation License''.

   If you have Invariant Sections, Front-Cover Texts and Back-Cover

Texts, replace the "with...Texts." line with this:

         with the Invariant Sections being LIST THEIR TITLES, with

         the Front-Cover Texts being LIST, and with the Back-Cover Texts

         being LIST.

   If you have Invariant Sections without Cover Texts, or some other

combination of the three, merge those two alternatives to suit the

situation.

   If your document contains nontrivial examples of program code, we

recommend releasing these examples in parallel under your choice of

free software license, such as the GNU General Public License, to

permit their use in free software.
