* app/composite/gimp-composite-generic.c
* app/composite/gimp-composite-mmx.c
* app/composite/gimp-composite-sse.c
Incorporated a very clean patch from starox-gimp@starox.org
(Frederic Leroy) which improves the generic performance of the
burn compositing function. Speed is improved at a cost of a 64k
look-up table which is probably manageable for 8bpp images, but at
larger bpp images (which currently are not supported by the GIMP)
this is unlikely to be tolerable.
The generic C implementation of the burn function uses this
look-up table, the mmx/sse implementations have been commented out.
* app/composite/gimp-composite-*test.c: a regression test now
iterates over 8388625 pixels per pass.
* app/composite/gimp-composite-mmx.c
* app/composite/gimp-composite-sse.c
* app/composite/gimp-composite-sse2.c:
Ensured that a clobbered condition code register is reflected in
the clobbered register list for each asm() statement.
This should FIX bug #147013.
* app/composite/gimp-composite.c (gimp_composite_init): Print the
list of active instruction sets if the --verbose command line
switch is ON (via be_verbose)
* app/composite/gimp-composite-x86.h: Factored code from the mmx,
and sse implementations.
* app/composite/make-installer.py: Raised the number of test
iterations from 1 to 10.

* app/composite/gimp-composite-vis-test.c:
Regenerated sources via make-installer.py
* app/composite/gimp-composite-regression.c: Added functions to
print the pixels in their various formats.
* app/composite/gimp-composite-{mmx,sse,sse2}.c: Removed the dodge
optimisation because it has the same problem that the divide
optimisation has.
* app/composite/make-install.py: When generating tests, use a
pixel field of random values.
* app/composite/gimp-composite-3dnow.c:
Incorrectly reported the inverse of whether not the 3dNow instruction set is
supported by the current CPU.
* app/composite/gimp-composite-{mmx,sse}.c:
Removed linkage of gimp_composite_divide_*. Something is
inexplicably broken, and this will get people working again
while I debug. This should close bug #125101.
* app/composite/make-install.py: migrated to new (trimmer) code and
removed dead code. Some beautification for generated code.
* app/composite/gimp-composite-{mmx,sse,sse2,3dnow,altivec,vis,generic}.{c,h}:
All init() functions are also a run-time check and now expected to
return TRUE/FALSE if the particular set of compositing functions can
be used.
* app/composite/gimp-composite.c: No longer has to determine if
the particular set of compositing functions can be used.
* app/composite/gimp-composite-{mmx,sse,sse2,3dnow,altivec,vis}-{install,test}.c:
Regenerated
* app/composite/test-composite.c: Deprecated, removed. All tests are automatically
generated and the code is in app/composite/gimp-composite-{mmx,sse,sse2,3dnow,altivec,vis}-test.c:
* app/composite/Makefile.am: removed unused references to test-composite.c
2003-09-27 Sven Neumann <sven@gimp.org>
* app/gui/info-window.c (info_window_update): improved readability
of this code by introducing a local GimpImage* variable.
* app/composite/gimp-composite-regression.c: use a matching format
string for an u_long variable (should probably use gulong instead).
* app/composite/make-installer.py: output a short note about what
tests are going to be run.

* app/composite/gimp-composite-sse.[ch]
* app/composite/gimp-composite-sse2.[ch]
* app/composite/gimp-composite-vis.[ch]
* app/composite/make-installer.py:
Make it such that when a test is run on the wrong kind of
machine, don't fail without an explanation.
* app/composite/gimp-composite-{mmx,sse,sse2,altivec,vis}.c: Regenerated.
* app/composite/gimp-composite-regression.[ch]: Ensure all ints
are now unsigned longs.
* app/composite/gimp-composite-sse2.c (gimp_composite_addition_rgba8_rgba8_rgba8_sse2):
Enclosed the troublesome (rather dense) asm construct in
__OPTIMIZE__ in which case the compiler can successfully
allocate enough registers to load up the asm()
* app/composite/gimp-composite-mmx.c
* app/composite/gimp-composite-sse.c: Replaced all memory
references in asm() constructs to references to "input" parameters
to the asm(). This should take care of any name mangling issues
(see bug #120893)
Beautified more code to conform to the gimp style guidelines.
No longer doing pointer math in assembly. This should ease some
of the issues of compiling on 64bit machines.
* app/composite/gimp-composite-sse-installer.c
* app/composite/gimp-composite-sse-test.c: Removed reference to
gimp_composite_overlay_* because this code is suspect.
* app/composite/gimp-composite-regression.[ch]: New function to
initialise a GimpCompositeContext
* Makefile.am: do not generate the test form of
gimp-composite-generic.c
* app/composite/gimp-composite-generic-test.c: unused, removed.
* app/composite/make-installer.py app/composite/*-test.c: New
tests were broken because the byte-for-byte checks checked the
same buffer against itself.
* app/composite/: Regenerated installers and testers.
* app/composite/make-install.py: increased tests of pixels to 1024*1024+1
* app/composite/gimp-composite-mmx.c (gimp_composite_overlay_rgba8_rgba8_rgba_mmx):
Backed out of the current build. Although the unit tests all
pass, the emperical evidence is that something is wrong with it.
* app/composite/gimp-composite-dispatch.[ch]: retired and removed.
* app/composite/Makefile.am: The 'test' target now builds and runs
all the tests in TESTS
Fixed typos of mismatched parenthesis in 'regenerate' target
* app/composite/Makefile.am: TESTS now include ss2 and 3dnow
instruction sets.
* app/composite/make-gimp-composite-dispatch.py: retired and removed.
* app/composite/gimp-composite.c: call the installers of all the
various instruction sets supplied by x86 type processors.
* app/base/base.c (base_init): Call gimp_composite_init() *before*
paint_funcs_setup() (preparation for retiring
app/paint-funcs/paint-funcs.c)
* app/composite/gimp-composite-sse2.[ch]
* app/composite/gimp-composite-3dnow.[ch]
* app/composite/gimp-composite-sse2-installer.c
* app/composite/gimp-composite-3dnow-installer.c:
Added
* app/composite/make-installer.py: generate regression test
programmes that take the command line arguments --iterations and
--n-pixels for the number of iterations of a set of tests, and the
number of pixels to use in each test, respectively.
Conditionally compile tests in order to build and run tests on
machines that can actually perform the tests.
Failing a regression test now causes remaining tests to be
skipped and a non-zero exit code by the programme.
* app/composite/gimp-composite-{mmx,sse,altivec,vis}-{installer,test}.c:
regnerated
* app/composite/gimp-composite-sse.c
(gimp_composite_overlay_rgba8_rgba8_rgba8_sse): fixed (rewrote)
* app/composite/make-installer.py:
command line option --iterations to set the number of iterations for a test.
command line option --n_ixels to set the number of pixels for a test.
* app/composite/gimp-composite-mmx.c
(gimp_composite_grain_merge_rgba8_rgba8_rgba8_mmx): fixed (rewrote)
(gimp_composite_overlay_rgba8_rgba8_rgba8_mmx): fixed (rewrote)
(gimp_composite_value_rgba8_rgba8_rgba8_mmx):
new testing shows it to be broken (temporarily removed from use)
* composite/ modularisation of the automatic compositing function
"wiring" to construct the table of compositing functions at
run-time instead of compile time.
The environment variable GIMP_COMPOSITE is a hexadecimal number
representing a bit-field used to set/reset options in the
gimp-composite code.
* gimp-composite-altivec.[ch]: added
* gimp-composite-altivec-installer.[ch]: added
* gimp-composite-vis.[ch]: added
* gimp-composite-vis-installer.[ch]: added
* gimp-composite-mmx-installer.[ch]: added
* gimp-composite-sse-installer.[ch]: added
* gimp-composite-altivec-test.[ch]: added
* gimp-composite-vis-test.[ch]: added
* gimp-composite-mmx-test.[ch]: added
* gimp-composite-sse-test.[ch]: added
* make-installer.py: Added meta programme for generating code to
1) construct a table of compositing functions indexed by
operation, and the pixel formats of the sources and destination,
and 2) generating code for regression testing of these compositing
functions against the same functions in gimp-composite-generic.c
* gimp-composite-mmx.c (xxxgimp_composite_overlay_rgba8_rgba8_rgba8_mmx):
removing from the current set of optimisations because it appears
to be broken.
* Makefile.am: modified regression testing targets to now build
gimp-composite-*-test where * is any of generic, mmx, sse,
altivec, and vis.
* gimp-composite.c: moved in initialisation code
gimp_composite_init() from gimp-composite-dispatch.c
* gimp-composite.c: removed gimp_composite_unsupported().
* gimp-composite.c: use cpu_accel() to determine at run-time which
set of optimisations are to be used.
* gimp-composite.c: conditionally compile code for ARCH_X86.
* make-gimp-composite-dispatch.c: retired. See make-installer.py
* gimp-composite-mmx.c (op_overlay): namespace cleanup, op_overlay()
and all of the constant values are now static
* gimp-composite-mmx.c, gimp-composite-sse.c: fixed bug with the
alpha mask being the address of the alpha mask, not the mask
itself.
* app/paint-funcs/paint-funcs.c: Check gimp_composite_options.use
to see if we should use the new code or the old code.
