Performs a packed bit test of two 256-bit or 128-bit float32 vectors to check ZF and CF flag settings. The corresponding Intel® AVX instruction is
- first source float32 vector
- second source float32 vector
Performs a packed bit test of
s2instruction and checks the status of the ZF and CF flags. The intrinsic returns 1 if both ZF and CF flags are not 1 (that is, both flags are not set), otherwise returns 0 (that is, one of the flags is set).
VTESTPDinstruction performs a bitwise comparison of all the sign bits of the single-precision elements in the first source operand and corresponding sign bits in the second source operand. If the AND of the first source operand sign bits with the second source operand sign bits produces all zeros, the ZF flag is set else the ZF flag is clear. If the AND of the inverted first source operand sign bits with the second source operand sign bits produces all zeros the CF flag is set, else the CF flag is clear.
_mm_testnzc_psintrinsic checks the ZF and CF flags according to results of the 128-bit float32 source vectors. The
_m256_testnzc_psintrinsic checks the ZF and CF flags according to the results of the 256-bit float32 s
