<p>bit.ops - Bitwise Opcodes</p>
<h1><a name="DESCRIPTION"
>DESCRIPTION</a></h1>
<p>Operations that deal with bits directly,
either individually or in groups.</p>
<p>The variant with an appended <b>s</b> like <b>bands</b> work on strings.</p>
<p>When making changes to any ops file,
run <code>make bootstrap-ops</code> to regenerate all generated ops files.</p>
<dl>
<dt><a name="band(inout_INT,_in_INT)"
><b>band</b>(inout INT,
in INT)</a></dt>
Set the bits of $1 according to the <b>and</b> of the corresponding bits from $1 and $2.
<dt><a name="band(out_INT,_in_INT,_in_INT)"
><b>band</b>(out INT,
in INT,
in INT)</a></dt>
Set the bits of $1 according to the <b>and</b> of the corresponding bits from $2 and $3.
<dt><a name="bor(inout_INT,_in_INT)"
><b>bor</b>(inout INT,
in INT)</a></dt>
Set the bits of $1 according to the <b>or</b> of the corresponding bits from $1 and $2.
<dt><a name="bor(out_INT,_in_INT,_in_INT)"
><b>bor</b>(out INT,
in INT,
in INT)</a></dt>
Set the bits of $1 according to the <b>or</b> of the corresponding bits from $2 and $3.
<dt><a name="shl(inout_INT,_in_INT)"
><b>shl</b>(inout INT,
in INT)</a></dt>
Shift left $1 by $2 bits.
<dt><a name="shl(out_INT,_in_INT,_in_INT)"
><b>shl</b>(out INT,
in INT,
in INT)</a></dt>
Set $1 to the value of $2 shifted left by $3 bits.
<dt><a name="shr(inout_INT,_in_INT)"
><b>shr</b>(inout INT,
in INT)</a></dt>
Shift right $1 by $2 bits.
<dt><a name="shr(out_INT,_in_INT,_in_INT)"
><b>shr</b>(out INT,
in INT,
in INT)</a></dt>
Set $1 to the value of $2 shifted right by $3 bits.
<dt><a name="lsr(out_INT,_in_INT)"
><b>lsr</b>(out INT,
in INT)</a></dt>
Shift $1 logically shifted right by $2 bits.
<dt><a name="lsr(out_INT,_in_INT,_in_INT)"
><b>lsr</b>(out INT,
in INT,
in INT)</a></dt>
Set $1 to the value of $2 logically shifted right by $3 bits.
<dt><a name="bxor(inout_INT,_in_INT)"
><b>bxor</b>(inout INT,
in INT)</a></dt>
Set the bits of $1 according to the <b>xor</b> of the corresponding bits from $1 and $2.
<dt><a name="bxor(out_INT,_in_INT,_in_INT)"
><b>bxor</b>(out INT,
in INT,
in INT)</a></dt>
