profile updates
profile.c: Major reworking. Keep track of new information -- total
function timing (includes descendants), GC usage, total GC usage
(includes descendants). New functions to be called appropriately
from eval.c, alloc.c to keep track of this information. Keep track
of when we're actually in a function vs. in its profile, for more
accurate timing counts. Track profile overhead separately. Create
new mechanism for specifying "internal sections" that are tracked
just like regular Lisp functions and even appear in the backtrace
if `backtrace-with-internal-sections' is non-nil (t by default
for error-checking builds). Add some KKCC information for the
straight (non-Elisp) hash table used by profile, which contains
Lisp objects in its keys -- but not used yet. Remove old ad-hoc
methods for tracking garbage collection, redisplay (which was
incorrect anyway when Lisp was called within these sections).
Don't record any tick info when blocking under MS Windows, since
the timer there is in real time rather than in process time.
Make `start-profiling', `stop-profiling' interactive. Be consistent
wrt. recursive functions and functions currently on the stack when
starting or stopping -- together these make implementing the
`total' values extremely difficult. When we start profiling, we
act as if we just entered all the functions currently on the stack.
Likewise when exiting. Create vars in_profile for tracking
time spent inside of profiling, and profiling_lock for setting
exclusive access to the main hash table when reading from it or
modifying it. (protects against getting screwed up by the signal
handle going off at the same time.
profile.h: New file.
Create macros for declaring internal profiling sections.
lisp.h: Move profile-related stuff to profile.h.
alloc.c: Keep track of total consing, for profile.
Tell profile when we are consing.
Use new profile-section method for noting garbage-collection.
alloc.c: Abort if we attempt to call the allocator reentrantly.
backtrace.h, eval.c: Add info for use by profile in the backtrace frame and transfer
PUSH_BACKTRACE/POP_BACKTRACE from eval.c, for use with profile.
elhash.c: Author comment.
eval.c, lisp.h: New Lisp var `backtrace-with-internal-sections'. Set to t when
error-checking is on.
eval.c: When unwinding,
eval.c: Report to profile when we are about-to-call and just-called wrt. a
function.
alloc.c, eval.c: Allow for "fake" backtrace frames, for internal sections (used by
profile and `backtrace-with-internal-sections'.
event-Xt.c, event-gtk.c, event-msw.c, event-tty.c: Record when we are actually blocking on an event, for profile's sake.
event-stream.c: Record internal profiling sections for getting, dispatching events.
extents.c: Record internal profiling sections for map_extents.
hash.c, hash.h: Add pregrow_hash_table_if_necessary(). (Used in profile code
since the signal handler is the main grower but can't allow
a realloc(). We make sure, at critical points, that the table
is large enough.)
lread.c: Create internal profiling sections for `load' (which may be triggered
internally by autoload, etc.).
redisplay.c: Remove old profile_redisplay_flag. Use new macros to declare
internal profiling section for redisplay.
text.c: Use new macros to declare internal profiling sections for
char-byte conversion and internal-external conversion.
SEMI-UNRELATED CHANGES:
-----------------------
text.c: Update the long comments.

Introduction Thank you for downloading XEmacs. We of the XEmacs development team believe user satisfaction is our number one priority, and we hope that you will be pleased with the power of our editor. Please follow all of the instructions in order to enjoy a quick and easy installation. Getting Started In this guide, information which you will need to supply will be enclosed in angle brackets, <like this>. Commands which you will have to enter will be indented, like this. You will need to provide a loading directory, in which to load the material from tape (/tmp/xemacs is recommended), and a permanent installation directory (/usr/local/xemacs is recommended). Loading From Tape First create and change directory to the loading directory: mkdir <working directory> cd <working directory> Now you are ready to load the software from tape. The specific device name needed to load the tape varies with hardware vendors, and may be found in Appendix A, "Vendors and Device Names". Load the software from tape: tar xvf /dev/<device name> You have now loaded all of the software from tape, and are ready to compile and install the XEmacs Text Editor. Compiling and Installing the XEmacs Editor Compiling and installing the libraries is handled by a user-friendly shell script. You will need to provide some information to the script, such as your organization name and registration number. To run the script, type /bin/sh xemacs/xemacs.install -d <installation directory> Follow the script's directions, and provide the information which it prompts for. When the script prompts you for the directory in which the distribution files are located, you will find that you are unable to provide it with any directory which the script will deem satisfactory. That is because it is necessary to order the following additional parts which are necessary to continue with the installation: Part Number Qty Name Price GM-96-3026 1 Goat, male 1000.00 CB-13-2395 1 Candle, black 50.00 CG-63-6376 1 Chalk dust container 10.00 IB-89-3335 5 Incense sticks 5.00 DE-44-8846 1 Dagger, ebon, curved 500.00 AS-87-2319 1 Altar, silver 10000.00 Wait until the additional parts arrive; you will be ready to continue the installation the next Friday the 13th at midnight. Ritual for Successfully Completing Installation Stand in front of the computer. Pour out the chalk dust in an inscribed pentagram around you; be sure that it is without breaks. Set an incense stick at each of the five corners, the altar in front of the computer, and the candle in front of the altar. Light each of the incense sticks and the candles, chanting in a low voice: Daemons and spirits of the netherworld Forces of all that is chaotic and mysterious Essence of Netscape and MicroSoft I am coming here to appease you I offer you this goat That my software may work I bind you here Do not make my system crash Let the software install as advertised Place the goat on the altar, and slaughter it with the dagger. May this goat feed you Sate your lust for blood Into it may your mischief fly Not my computer Make the software work For this is the only way Then spit into the computer's ventilation slots. This will complete different circuits inside the computer, causing its motherboard and cards to function in ways that the engineers never intended, thereby making your system compatible with our libraries. Reboot your computer. The installation is now complete. [This has undergone a minor rewrite for XEmacs.
