clz alias clz = __builtin_clz: Undocumented in source.
moveMask alias moveMask = __builtin_ia32_pmovmskb128: Undocumented in source.

alignPtrNext T* alignPtrNext(T* ptr, size_t pot): Aligns a pointer to the closest multiple of pot (a power of two), which is equal to or larger than value.
bsf int bsf(ulong u): Undocumented in source. Be warned that the author may not have intended to support it.
bsr int bsr(ulong u): Undocumented in source. Be warned that the author may not have intended to support it.
clz ubyte clz(U u): Count leading zeroes.
clz ubyte clz(ulong u): Undocumented in source. Be warned that the author may not have intended to support it.
clz ubyte clz(ulong u): Undocumented in source. Be warned that the author may not have intended to support it.
clz ubyte clz(U u): Undocumented in source. Be warned that the author may not have intended to support it.
ctfeJoin enum ctfeJoin(string fmt, string joiner): Generates a mixin string for repeating code. It can be used to unroll variadic arguments. A format string is instantiated a certain number times with an incrementing parameter. The results are then concatenated using an optional joiner.
getUDA enum getUDA(): Undocumented in source. Be warned that the author may not have intended to support it.
moveMask uint moveMask(ubyte16 ): Undocumented in source.

isPowerOf2 bool isPowerOf2 [@property getter]: Returns whether the (positive) argument is an integral power of two.

FieldNameTuple template FieldNameTuple(T): Get as an expression tuple the names of the fields of a struct, class, or union. This consists of the fields that take up memory space, excluding the hidden fields like the virtual function table pointer or a context pointer for nested types. If T isn't a struct, class, or union returns an expression tuple with an empty string.
SIMDFromScalar template SIMDFromScalar(V, alias scalar): Undocumented in source.
SIMDFromString template SIMDFromString(string str): Undocumented in source.
UnsignedOf template UnsignedOf(I): For any integral type, returns the unsigned type of the same bit-width.
staticIota template staticIota(int beg, int end): Undocumented in source.
