31 /* Define some macros which can expand into proxy functions between
32 * ARM assembly optimized functions and the rest of pixman fast path API.
33 *
34 * All the low level ARM assembly functions have to use ARM EABI
35 * calling convention and take up to 8 arguments:
36 * width, height, dst, dst_stride, src, src_stride, mask, mask_stride
37 *
38 * The arguments are ordered with the most important coming first (the
39 * first 4 arguments are passed to function in registers, the rest are
40 * on stack). The last arguments are optional, for example if the
41 * function is not using mask, then 'mask' and 'mask_stride' can be
42 * omitted when doing a function call.
43 *
44 * Arguments 'src' and 'mask' contain either a pointer to the top left
45 * pixel of the composited rectangle or a pixel color value depending
46 * on the function type. In the case of just a color value (solid source
47 * or mask), the corresponding stride argument is unused.
