2012-02-24Disable MMX when Clang is being used.Søren Sandmann Pedersen1-0/+3
There are several issues with the Clang compiler and pixman-mmx.c: - When not optimizing, it doesn't seem to recognize that an argument to an __always_inline__ function is compile-time constant. This results in this error being produced: fatal error: error in backend: Invalid operand for inline asm constraint 'K'! - This inline assembly: asm ("pmulhuw %1, %0\n\t" : "+y" (__A) : "y" (__B) ); results in fatal error: error in backend: Unsupported asm: input constraint with a matching output constraint of incompatible type! So disable MMX when the compiler is Clang.

2012-01-10test: Port composite test over to use new pixel_checker_t object.Søren Sandmann Pedersen1-195/+95
Also make some tweaks to the way the errors are printed.
2012-01-10test: Add a new "pixel_checker_t" object.Søren Sandmann Pedersen2-0/+166
Add a new pixel_checker_t object to test/utils.[ch]. This object should be initialized with a format and can then be used to check whether a given "real" pixel in that format is close enough to a "perfect" pixel given as a double precision ARGB struct. The acceptable deviation is calcuated as follows. Each channel of the perfect pixel has 0.004 subtracted from it and is then converted to the format. The resulting value is the minimum value that will be accepted. Similarly, to compute the maximum value, the channel has 0.004 added to it and is then converted to the given format. Checking a pixel is then a matter of splitting it into channels and checking that each is within the computed bounds. The value of 0.004 was chosen because it is the minimum one that will make the existing composite test pass (see next commit). A problem with this value is that it causes 0xFE to be acceptable when the correct value is 1.0, and 0x01 to be acceptable when the correct value is 0. It would be better if, when the result is exactly 0 or exactly 1, an a8r8g8b8 pixel were required to produce exactly 0x00 or 0xff to preserve full black and full white. A deviation value of 0.003 would produce this, but currently this would cause tests with operators that involve divisions to fail.

2012-01-10Get rid of delegates for combinersSøren Sandmann Pedersen3-134/+34
Add a new function _pixman_implementation_lookup_combiner() that will find a usable combiner given an operator and information about whether the combiner should apply component alpha and whether it should be 64 bit. In pixman-general.c use this function to look up a combiner up front instead of walking the delegate chain for every scanline.
2012-01-10test/alphamap.c: Make dst and orig_dst more independent of each otherSøren Sandmann Pedersen1-27/+32
When making the copy of the destination, do so separately for the image and the alpha map. This ensures that the alpha channel of the alpha map will be different from the alpha channel of the actual image. Previously, orig_dst would be copied onto dst along with its alpha map, which mean that the alpha map of orig_dst would become the new alpha channel of *both* dst and dst's alpha map. This meant that test didn't actually test that the alpha maps alpha channel was actually fetched.
2012-01-10Fix bugs with alpha mapsSøren Sandmann Pedersen1-11/+42
The alpha channel from the alpha map must be inserted as the new alpha channel when a scanline is fetched from an image. Previously the alpha map would overwrite the buffer instead. This wasn't caught be the alpha map test because it would only verify that the resulting alpha channel was correct, and not pay attention to incorrect color channels.
2012-01-10test: In the alphamap test, also test that we get the right red valueSøren Sandmann Pedersen1-6/+79
There is a bug where the red channel of the alpha map of the destination image is used instead of the red channel of the destination image itself.

2012-01-09Reject trapezoids where top (botttom) is above (below) the edgesSøren Sandmann Pedersen2-5/+9
When a trapezoid has a top/bottom that is above/below the left/right edges, degenerate trapezoids become possible. For example the edge could be very short and close to horizontal. If the bottom edge is far below the bottom point of such a short edge, the result is that the lower right corner of the trapezoid will be extremely far to the left. This kind of trapezoid causes overflows in the rasterization code, so change pixman_trapezoid_valid() to reject them.
2012-01-09In MUL_UNc() cast to comp2_tSøren Sandmann Pedersen1-1/+1
Otherwise, when comp1_t is 16 bits wide, we can end up with a signed integer overflow.
2012-01-09Fix a bunch of signed overflow issuesSøren Sandmann Pedersen6-22/+39
In pixman-fast-path.c: (1 << 31) - 1 causes a signed overflow, so change to (1U << n) - 1. In pixman-image.c: The check for whether m10 == -m01 will overflow when -m01 == INT_MIN. Instead just check whether the variables are 1 and -1. In pixman-utils.c: When the depth of the topmost channel is 0, we can end up shifting by 32. In blitters-test.c: Replicating the mask would end up shifting more than 32. In region-contains-test.c: Computing the average of two large integers could overflow. Instead add half the difference between them to the first integer. In stress-test.c: Masking the value in fake_reader() would sometimes shift by 32. Instead just use the most significant bits instead of the least significant. All these issues were found by the IOC tool: http://embed.cs.utah.edu/ioc/
