WebMay 12, 2024 · It seems to be a "gcc issue" when code calls intrinsic function _addcarry_u32. Indeed, the output is correct when either of the below happens: clang or icc is selected; the call to _addcarry_u32 is replaced by expression b += a (which generates the same assembly instructions for -O1 level). Another thing that plays a role is the …

WebUnfortunately compilers and in particular GCC are not very good at optimizing big integers and/or cryptographic code even when using intrinsics like addcarry_u64. Compilers with proper support of addcarry_u64 like Clang, MSVC and ICC may generate code up to 20~25% faster than GCC.

Clang 3.7 and GCC 5.2 still don't produce efficient code with this intrinsic. Clang in addition has a built-in which one would think does this, __builtin_addcll, but it does not produce efficient code either.
