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