// If we have SSSE3 support, pick off 12 bytes at a time for as long as we can.
// But because we read 16 bytes at a time, ensure we have enough room to do a
// full 16-byte read without segfaulting:
while (srclen >= 16)
{
// Load string:
__m128i str = _mm_loadu_si128((__m128i *)c);
// Reshuffle:
str = enc_reshuffle(str);
// Translate reshuffled bytes to the Base64 alphabet:
str = enc_translate(str);
// Store:
_mm_storeu_si128((__m128i *)o, str);
c += 12; // 3 * 4 bytes of input
o += 16; // 4 * 4 bytes of output
outl += 16;
srclen -= 12;
