2012-06-02Turn all the fetchers into proper iter_get_scanlines_tbits-iterSøren Sandmann Pedersen2-104/+114
This avoids an extra indirection and may later on let the functions cache some more information between calls. Also, this lets us get rid of get_scanline_32/64 in pixman_image_t.
2012-05-30Make use of image flags in mmx and sse2 iteratorsSøren Sandmann Pedersen2-20/+8
Now that we have the full image flags available, the SSE2 and MMX iterators can simply check against SAMPLES_COVER_CLIP_NEAREST (which is computed in pixman_image_composite32()) instead of comparing all the x/y/width/height parameters.
2012-05-30Pass the full image flags to iteratorsSøren Sandmann Pedersen12-33/+40
When pixman_image_composite32() is called some flags are computed that indicate various things about the composite operation that can't be deduced from the image flags themselves. These additional flags are not currently available to iterators. All they can do is read the image flags in image->common.flags. Fix that by passing the info->{src, mask, dest}_flags on to the iterator initialization and store the flags in the iter struct as "image_flags". At the same time rename the *iterator* flags variable to "iter_flags" to avoid confusion.

2012-05-24test: Composite with solid images instead of using pixman_image_fill_*Søren Sandmann Pedersen2-11/+15
There is a couple of places where the test suite uses the pixman_image_fill_* functions to initialize images. These functions can fail, and will do so if the "fast" implementation is disabled. So to make sure the test suite passes even using PIXMAN_DISABLE="fast", use pixman_image_composite32() with a solid image instead of pixman_image_fill_*.

2012-05-23MIPS: DSPr2: Fix bug in over_n_8888_8888_ca/over_n_8888_0565_ca routinesNemanja Lukic1-32/+28
In main loop (unrolled by factor 2), instead of negating multiplied mask values by srca, values of srca was negated, and passed as alpha argument for UN8x4_MUL_UN8x4_ADD_UN8x4 macro. Instead of: ma = ~ma; UN8x4_MUL_UN8x4_ADD_UN8x4 (d, ma, s); Code was doing this: ma = ~srca; UN8x4_MUL_UN8x4_ADD_UN8x4 (d, ma, s); Key is in substituting registers s0/s1 (containing srca value), with t0/t1 containing mask values multiplied by srca. Register usage is also improved (less registers are saved on stack, for over_n_8888_8888_ca routine). The bug was introduced in commit d2ee5631 and revealed by composite test.

2012-05-15configure.ac: Fail the ARM/iwMMXt test if not compiling with -march=iwmmxtMatt Turner1-0/+3
If not compiling with -march=iwmmxt, the configure test will still pass, thinking that the __builtin_arm_* intrinsic is a function instead of generating a single instruction. Since no linking is done, the configure test doesn't catch this, and we get linking errors in the build.

The pack_4x565 makes use of the pack_4xpacked565 function which uses pmadd.

Uses the pmadd technique described in http://software.intel.com/sites/landingpage/legacy/mmx/MMX_App_24-16_Bit_Conversion.pdf The technique uses the packssdw instruction which uses signed saturatation. This works in their example because they pack 888 to 555 leaving the high bit as zero. For packing to 565, it is unsuitable, so we replace it with an or+shuffle.

2012-04-27mmx: Use Loongson pinsrh instruction in pack_565Matt Turner2-0/+25
The pinsrh instruction is analogous to MMX EXT's pinsrw, except like other Loongson vector instructions it cannot access the general purpose registers. In the cases of other Loongson vector instructions, this is a headache, but it is actually a good thing here. Since the instruction is different from MMX, I've named the intrinsic loongson_insert_pi16. text data bss dec hex filename 25976 1952 0 27928 6d18 .libs/libpixman_loongson_mmi_la-pixman-mmx.o 25336 1952 0 27288 6a98 .libs/libpixman_loongson_mmi_la-pixman-mmx.o -and: 181 +and: 147 -dsll: 143 +dsll: 95 -dsrl: 87 +dsrl: 135 -ldc1: 523 +ldc1: 462 -lw: 767 +lw: 721 +pinsrh: 35
2012-04-27mmx: don't pack and unpack src unnecessarilyMatt Turner1-47/+35
The combine function was store8888'ing the result, and all consumers were immediately load8888'ing it, causing lots of unnecessary pack and unpack instructions. It's a very straight forward conversion, except for mmx_combine_over_u and mmx_combine_saturate_u. mmx_combine_over_u was testing the integer result to skip pixels, so we use the is_* functions to test the __m64 data directly without loading it into an integer register. For mmx_combine_saturate_u there's not a lot we can do, since it uses DIV_UN8.
