--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Because this is exactly what the C standard says it should be.
See https://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf 6.4.4.1/5 .
For hex (and Octal) constants, if the value is not representable in `signed
long long` (which it is not as it is too big) but representable as `unsigned
long long` then unsigned long long is chosen for LL.
For Decimals, it is just signed.
