Originally posted by: TracyR IBM XL C/C++ for AIX, V13.1 supports a vector population count procedure vec popcnt. This built-in function computes the population count (number of set bits) in each element of their input. This function is valid only when the -qarch option is set to target...
Originally posted by: TracyR In IBM XL C/C++ for Linux, V13.1, we support a vector built-in function vec gbb that can perform a gather-bits-by-bytes operation on the input. NOTE: This built-in function is valid only when -qarch is set to target POWER8™ processors. Syntax ...
