* acinclude.m4
* m4macros/Makefile.am
* m4macros/detectcflags.m4: new macro: GIMP_DETECT_CFLAGS; used
to detect which of a set of compiler options a compiler supports.
* configure.in: use the above for the altivec and -fno-strict-aliasing
flags. Also, use it to detect the presence of -mmmx and -msse, since
those are needed to compile even MMX/SSE assembly with gcc 4.0. Define
MMX/SSE_EXTRA_CFLAGS.
* app/composite/Makefile.am: compile each of the composite flavors
into their own library, so we can use automake's per-target CFLAGS.
Use MMX/SSE/ALTIVEC_EXTRA_CFLAGS in the appropriate places. Build
libappcomposite.a out of the resulting objects.
* app/composite/gimp-composite-3dnow.c
* app/composite/gimp-composite-altivec.c
* app/composite/gimp-composite-mmx.c
* app/composite/gimp-composite-sse.c
* app/composite/gimp-composite-sse2.c
* app/composite/gimp-composite-vis.c
* app/composite/make-installer.py: move the _init functions into
the installers, so only actually mmx/sse/etc. code gets compiled
under the appropriate CFLAGS.
* app/composite/gimp-composite-3dnow-installer.c
* app/composite/gimp-composite-altivec-installer.c
* app/composite/gimp-composite-mmx-installer.c
* app/composite/gimp-composite-sse-installer.c
* app/composite/gimp-composite-sse2-installer.c
* app/composite/gimp-composite-vis-installer.c: regenerated.
* app/composite/gimp-composite.c: remove useless cpu-accel.h include.
* app/composite/gimp-composite-sse2.c:
Trying to be more flexible in register use so the compiler can do
reloads without running out of registers when using optimisation
modes other than 2.
Avoid the message "error: can't find a register in class
`GENERAL_REGS' while reloading `asm'"
* app/composite/gimp-composite-x86.h
Use more newlines in asm() macros to ensure that gcc gets the
instruction count correct. This is partially complete as of this
commit.
* app/composite/gimp-composite-sse2.c: Repaired a latent bug in
gimp_composite_lighten_rgba8_rgba8_rgba8_sse2 where setting up
the alpha masks were not done correctly. A redundant (better?)
fix to bug #164061
Use movntq instructions to avoid processor cache pollution.
Some adjustments to register allocation specifications.

* app/composite/gimp-composite-sse2.c
(gimp_composite_lighten_rgba8_rgba8_rgba8_sse2): applied a patch
from Joao S. O. Bueno Calligaris that changes the SSE2 code to
load the proper register. Fixes bug #164061.
* app/composite/gimp-composite-x86.h
* app/composite/gimp-composite-sse.c
* app/composite/gimp-composite-sse2.c: Fixed a bunch of
warnings due to bad type casting.
* app/composite/gimp-composite-mmx.c
* app/composite/gimp-composite-sse.c
* app/composite/gimp-composite-x86.h
* app/composite/gimp-composite-sse2.c:
The last changes to fix the the clobber registers bug #147013.
Commented out some dead code to be reviewed later.
* app/composite/gimp-composite-sse.c
* app/composite/gimp-composite-sse2.c: More updates to accomodate
the clobber registers. Additional progress against bug #147013.
* app/composite/gimp-composite-sse.h: Fixed a bug where the wrong
manifest constant definition caused sse2 instructions to never be
compiled.
identifies itself as GCC, but doesn't support the same extended
assembly features/misfeatures as GCC. With the help of the Intel
compiler group, we've determined that the Intel compiler can be
identified at compile time by the definition of the preprocessor
variable __INTEL_COMPILER.
These changes make all of the assembly code currently written to
simply avoid the Intel compiler.
This is an interim solution to get a build working despite the
Intel compiler. A more correct solution has been identified, see
the discussion of bug #147013 for more information.
* 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/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

* app/composite/gimp-composite-vis.c: moved includes out of the
#if __GNUC__ >= 3 to make the code compile on other compilers.

* app/composite/gimp-composite-sse.[ch]
* app/composite/gimp-composite-sse2.[ch]

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-sse2.c (gimp_composite_swap_rgba8_rgba8_rgba8_sse2):
Removed clobbered register declaration in an attempt to get this
to compile with gcc 3.2.3
* gimp-composite-sse2-installer.c, gimp-composite-sse2-test.c:
regenerated with new functions.
* gimp-composite-sse.c, gimp-composite-sse2.c:
Distinguish between 64bit and 128bit constants with a little
faux hungarian notation.
* gimp-composite-sse2.[ch]: Added implementations of
addition_rgba8_rgba8_rgba8, subtract_rgba8_rgba8_rgba8, and
swap_rgba8_rgba8_rgba8
* gimp-composite-generic.c:
Some formating beautification
* app/composite/gimp-composite-mmx.c
app/composite/gimp-composite-sse.c
app/composite/gimp-composite-sse2.c:
Convert "unsigned long" to guint32 in preparation for 64bit
machinery.
2003-09-04 Manish Singh <yosh@gimp.org>
* configure.in: #define ARCH_X86 on x86-64 too.
* app/composite/gimp-composite-sse2.c: dererference pointers outside
of asm() construct.
Now this stuff builds on x86-64, but fails some of the tests. Need
to fix it later.
* 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.
