CSET -- A64

CSET

Conditional Set sets the destination register to 1 if the condition is TRUE, and otherwise sets it to 0.

This is an alias of CSINC. This means:

The encodings in this description are named to match the encodings of CSINC.
The description of CSINC gives the operational pseudocode for this instruction.

32-bit (sf == 0)

CSET <Wd>, <cond>

is equivalent to

CSINC <Wd>, WZR, WZR, invert(<cond>)

and is always the preferred disassembly.

64-bit (sf == 1)

CSET <Xd>, <cond>

is equivalent to

CSINC <Xd>, XZR, XZR, invert(<cond>)

and is always the preferred disassembly.

Assembler Symbols

<Wd>	Is the 32-bit name of the general-purpose destination register, encoded in the "Rd" field.

<Xd>	Is the 64-bit name of the general-purpose destination register, encoded in the "Rd" field.

<cond>

Is one of the standard conditions, excluding AL and NV, encoded in the "cond" field with its least significant bit inverted.

Operation

The description of CSINC gives the operational pseudocode for this instruction.
