Floating-point compare less than vector.
Compare active floating-point elements in the first source vector being less than corresponding elements in the second source vector, and place the boolean results of the comparison in the corresponding elements of the destination predicate. Inactive elements in the destination predicate register are set to zero. Does not set the condition flags.
This is an alias of FCM<cc> (vectors). This means:
31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
0 | 1 | 1 | 0 | 0 | 1 | 0 | 1 | size | 0 | Zm | 0 | 1 | 0 | Pg | Zn | 1 | Pd |
FCMLT <Pd>.<T>, <Pg>/Z, <Zm>.<T>, <Zn>.<T>
is equivalent to
FCMGT <Pd>.<T>, <Pg>/Z, <Zn>.<T>, <Zm>.<T>
but is never the preferred disassembly.
<Pd> |
Is the name of the destination scalable predicate register, encoded in the "Pd" field. |
<Zm> |
Is the name of the second source scalable vector register, encoded in the "Zm" field. |
<Zn> |
Is the name of the first source scalable vector register, encoded in the "Zn" field. |
<T> |
Is the size specifier,
encoded in
size:
|
<Pg> |
Is the name of the governing scalable predicate register P0-P7, encoded in the "Pg" field. |
The description of FCM<cc> (vectors) gives the operational pseudocode for this instruction.
