With the `cmp` operation the comparison operators ==, !=, <, <=, >, >=, <=>
can be applied.
Its first argument is an attribute that defines the comparison operator:
- equal to (mnemonic: `"eq"`; integer value: `0`)
- not equal to (mnemonic: `"ne"`; integer value: `1`)
- less than (mnemonic: `"lt"`; integer value: `2`)
- less than or equal to (mnemonic: `"le"`; integer value: `3`)
- greater than (mnemonic: `"gt"`; integer value: `4`)
- greater than or equal to (mnemonic: `"ge"`; integer value: `5`)
- three-way-comparison (mnemonic: `"three_way"`; integer value: `6`)
Example:
```mlir
// Custom form of the cmp operation.
