=== c.not

Synopsis::
Bitwise not, 16-bit encoding

Mnemonic::
c.not _rd'/rs1'_

Encoding (RV32, RV64)::
[wavedrom, , svg]
....
{reg:[
    { bits:  2, name: 0x1, attr: ['C1'] },
    { bits:  3, name: 0x5, attr: ['C.NOT'] },
    { bits:  2, name: 0x3, attr: ['FUNCT2'] },
    { bits:  3, name: 'rd\'/rs1\'', attr: ['SRCDST'] },
    { bits:  3, name: 0x7 },
    { bits:  3, name: 0x4, attr: ['FUNCT3'] },
],config:{bits:16}}
....

Description::
This instruction takes the one's complement of _rd'/rs1'_ and writes the result to the same register.

[NOTE]
  _rd'/rs1'_ is from the standard 8-register set x8-x15.

Prerequisites::
None

32-bit equivalent::
[source,sail]
--
xori rd, rs, -1
--

[NOTE]

  The SAIL module variable for _rd'/rs1'_ is called _rsdc_.

Operation::
[source,sail]
--
X(rsdc) = X(rsdc) XOR -1;
--
