Performs a packed bit test of two integer vectors to set the ZF flag. The corresponding Intel® AVX instruction is
- first source integer vector
- second source integer vector
Allows setting of the ZF flag. The ZF flag is set based on the result of a bitwise AND operation between the first and second source vectors. The corresponding instruction
VPTESTsets the ZF flag if all the resulting bits are 0. If the resulting bits are non-zeros, the instruction clears the ZF flag.
Non-zero if ZF flag is set
Zero if the ZF flag is not set
