     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.
