// in the bit-reflected ("twisted") representation that gcm_init_v8 uses and
// m(A,B) packs the Karatsuba middle terms A.lo ^ A.hi (low 64 bits) and
// B.lo ^ B.hi (high 64 bits) of the two neighbouring powers into one entry;
// four powers suffice because GHASH is folded four blocks at a time, and

// Origin: derived from the 'clean' (readability-oriented) AArch64 AES-GCM
// implementation by Hanno Becker, itself derived from the assembly generated by
// aesv8-gcm-armv8.pl (Fangming Fang, OpenSSL) and ultimately from ARM's
// AArch64cryptolib (Samuel Lee).  The main four-block loop is software-pipelined
// and the whole kernel rescheduled with the SLOTHY superoptimizer; the
// surrounding assembler boilerplate follows the s2n-bignum house style.
