Convert strings to little endian hexadecimal representation for fast, optimization-friendly comparisons in native languages (this was written to help with the development of a C99 program where the compiler was not cooperating).
Currently hand limited to 64 bytes because it doesn't really make any sense (for my use case) to generate a constant bigger than what can fit in an avx512 register, but the code allows for arbitrarily long strings to be converted, just remove the if statement.
Hello turns into 6f6c6c6548
Little-endian turns into 6e6169646e652d656c7474694c
If you need it to consider the null terminator too, just add a 00 in front of the number :).
