- **VCMPEQUD** "Vector Compare Equal Unsigned Doubleword". This instruction is used to compare the corresponding doublewords (64-bit elements) in two vector registers for equality. - **VCMPEQUD** "Vector Compare Equal Unsigned Doubleword". This instruction is used to compare the corresponding doublewords (64-bit elements) in two vector registers for equality.
- **VCMPEQUDCC** "Vector Compare Equal Unsigned Doubleword and Conditionally Clear". This instruction is used to compare two vector registers for equality on a doubleword (64-bit) basis. The instruction compares the doublewords in the source registers for equality. If the doublewords are equal, the corresponding element in the result is set to all ones; otherwise, it is set to all zeros. The result of the comparison is stored in the condition register field CR6. If the comparison result is true (all ones), the instruction also clears the condition register field CR6.
