// The exported functions in this file have got the following signature:
// void itxfm_add(pixel *dst, ptrdiff_t dst_stride, coef *coeff, int eob,
// int bitdepth_max);
// Most of the functions use the following register layout:
// x0-x3 external parameters
// x4 function pointer to first transform
// x5 function pointer to second transform
// x6 output parameter for helper function
// x7 input parameter for helper function
// x8 input stride for helper function
// x9-x12 scratch variables for helper functions
// x13 pointer to list of eob thresholds
// x14 return pointer for helper function
// x15 return pointer for main function
// The SIMD registers most often use the following layout:
// v0-v1 multiplication coefficients
// v2-v7 scratch registers
// v8-v15 unused
// v16-v31 inputs/outputs of transforms
