Each bit of result is corresponding bit of a if corresponding bit of c is 0.
gentype bitselect(gentype a,
gentype b,
gentype c)halfn bitselect (halfn a, halfn b,
halfn c) // if half extension enabled
Description
Each bit of result is corresponding bit of a if corresponding bit of c is 0.
Otherwise it is the corresponding bit of b.
Notes
If an implementation extends this specification to support IEEE-754 flags or exceptions, then all built-in relational functions shall proceed without raising the invalid floating-point exception when one or more of the operands are NaNs.
The built-in relational functions are extended with cl_khr_fp16 to include versions that take half, and half{2|3|4|8|16} as arguments.
The argment type gentype can be char, charn, uchar, ucharn, short, shortn, ushort, ushortn, int, intn, uint, uintn, long, longn, ulong, ulongn, float, floatn, double, and doublen.
