    how to print __uint128_t number using gcc? Is there PRIu128 that behaves similar to PRIu64 from : No. Instead to print in decimal, print to a string. The size of string buffer needed is just enough to do the job per the value of x.

Using the GNU Compiler Collection (GCC): __int128

    https://gcc.gnu.org/onlinedocs/gcc/_005f_005fint128.html
    6.9 128-bit Integers. As an extension the integer scalar type __int128 is supported for targets which have an integer mode wide enough to hold 128 bits. Simply write __int128 for a signed 128-bit integer, or unsigned __int128 for an unsigned 128-bit integer. There is no support in GCC for expressing an integer constant of type __int128 for targets with long long integer less than 128 bits wide.

    May 11, 2013 · Although you are right that it doesn't really matter since the calling convention doesn't distinguish between the type of the object like it does on linux. x86_64 is little endian, so the lo byte should be first. Taking that into account the assembly seems to agree with GCC.

    GCC, Clang, and Intel ICC all support a built-in __int128 type. Microsoft MSVC does not support any 128-bit integral type as far as I’m aware. On GCC, Clang, and ICC, __int128 is a token similar to int: you can modify it with unsigned to produce unsigned __int128.However, all three front-ends also support the built-in synonyms __int128_t and __uint128_t.
