NAME

bit.ops - Bitwise Opcodes

DESCRIPTION

Operations that deal with bits directly, either individually or in groups.

The variant with an appended s like bands work on strings.

When making changes to any ops file, run make bootstrap-ops to regenerate all generated ops files.

band(inout INT, in INT)

Set the bits of $1 according to the and of the corresponding bits from $1 and $2.

band(out INT, in INT, in INT)

Set the bits of $1 according to the and of the corresponding bits from $2 and $3.

bor(inout INT, in INT)

Set the bits of $1 according to the or of the corresponding bits from $1 and $2.

bor(out INT, in INT, in INT)

Set the bits of $1 according to the or of the corresponding bits from $2 and $3.

shl(inout INT, in INT)

Shift left $1 by $2 bits.

shl(out INT, in INT, in INT)

Set $1 to the value of $2 shifted left by $3 bits.

shr(inout INT, in INT)

Shift right $1 by $2 bits.

shr(out INT, in INT, in INT)

Set $1 to the value of $2 shifted right by $3 bits.

lsr(out INT, in INT)

Shift $1 logically shifted right by $2 bits.

lsr(out INT, in INT, in INT)

Set $1 to the value of $2 logically shifted right by $3 bits.

bxor(inout INT, in INT)

Set the bits of $1 according to the xor of the corresponding bits from $1 and $2.

bxor(out INT, in INT, in INT)

Set the bits of $1 according to the xor of the corresponding bits from $2 and $3.
