Or should that be 'longer long', 'longerer long', 'longest long'? ;)

longest is sadly not future proof, but longer is nice, I propose (forgoing any copyright claims, if the C standard committee is reading ;-)), ordered by increasing width:

long
longer
long long
long longer
longer long
longer longer

(sorry couldn't resist)

As long as we get `biggulp long` to store our AVX4096 registers as scalars too :) .

AVX4096? Why are you using such a small, and imprecise (and OLD) extension. Everyone now days knows that AVX4096K is the bare minimum.

can't we just have

int32
int64
int128

and, as a nod to those weird old architectures out there with 6 or 9 or whatever-bit bytes, those types are simply defined as the smallest power-of-two bytes that contain that number of bits.

Might be a bit wasteful of bits - the old ICL would need 16 6-bit bytes for an int64 (96 bits) - but then it probably doesn't have enough RAM for a program to want an int64 :-)

Move into the 21st century, guys :-), let history catch up if it wants to!

Cheers,
Wol

Aka int_least64_t and friends?

Terry Cavanagh solved the problem with future proofing longest in Super Hexagon:

long longer longest longester longestest longestester etc.

How about _BitInt(128)? This might even already work

One of the problems with teaching rocks to think is they start counting like Discworld Trolls: One, Two, Many, Lots.

How about "even longer"? ;)

And, in the opposite direction, can we also get a "rather short"? ^^
