Conditional Invert returns, in the destination register, the bitwise inversion of the value of the source register if the condition is TRUE, and otherwise returns the value of the source register.
This is an alias of CSINV. 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 |
sf | 1 | 0 | 1 | 1 | 0 | 1 | 0 | 1 | 0 | 0 | != 11111 | != 111x | 0 | 0 | != 11111 | Rd | |||||||||||||||

is equivalent to
CSINV <Wd>, <Wn>, <Wn>, invert(<cond>)
and is the preferred disassembly when Rn == Rm.
is equivalent to
CSINV <Xd>, <Xn>, <Xn>, invert(<cond>)
and is the preferred disassembly when Rn == Rm.
<Wd> |
Is the 32-bit name of the general-purpose destination register, encoded in the "Rd" field. |
<Wn> |
Is the 32-bit name of the general-purpose source register, encoded in the "Rn" and "Rm" fields. |
<Xd> |
Is the 64-bit name of the general-purpose destination register, encoded in the "Rd" field. |
<Xn> |
Is the 64-bit name of the general-purpose source register, encoded in the "Rn" and "Rm" fields. |
<cond> |
Is one of the standard conditions, excluding AL and NV, encoded in the "cond" field with its least significant bit inverted. |
The description of CSINV gives the operational pseudocode for this instruction.
