## Examples - MUL dest:reg, count:u64
This: Multiply the first COUNT "arg" registers and place the result in DEST.
```lisp
(format t "Hello World~%")
```
Compiles into:
```text
INTERN_LIT val0, "Hello World~%"
```
This: - DIV dest:reg, count:u64
```lisp Divide "arg0" by the product of the COUNT - 1 "arg" registers starting from "arg1"
(defun foo (bar &key baz &rest qux)
"FOO each of BAR and BAZ as well as each of QUX."
(let (some-val (genval bar))
(foo-internal some-val :baz baz qux)))
(foo 10 :baz 20) - INT_DIV dest:reg, val1:reg, val2:reg
``` Divide VAL1 by VAL2 and place the integer part of the result in DEST.
Compiles into:
```text - RECIP dest:reg, val:reg
NEWFUNCTION val0, 13 ;; not counting this instruction Divide 1 by VAL and place the result in DEST.
ENTER_LEXENV
INTERN_LIT saved0, "foo" - MOD dest:reg, val1:reg, val2:reg
ENTER_BLOCK saved0, 9 ;; not counting this instruction Divide VAL1 by VAL2 and place the remainder in DEST.
INTERN_LIT val0, "genval"
;; NOTE bar already in arg0 - SQRT dest:reg, val:reg
FUNCALL val0 ;; NOTE val0 clobbered here Take the square root of VAL and place it in DEST.
INTERN_LIT val0, "foo-internal"
MOV arg0, ret0 - POW dest:reg, base:reg, exp:reg
MOV arg3, arg2 Raise BASE to the EXP power and place the result in DEST.
MOV arg2, arg1
INTERN_LIT arg1, ":baz" - LN dest:reg, val:reg
FUNCALL val0 Take the natural log of VAL and place the result in DEST.
LEAVE_BLOCK saved0
LEAVE_LEXENV - EXP dest:reg, val:reg
Take the exponential function at VAL and place the result in DEST.
- SIN dest:reg, val:reg
COS dest:reg, val:reg
TAN dest:reg, val:reg
Take the sine, cosine, or tangent of VAL (in radians) and place it into DEST.
- ASIN dest:reg, val:reg
ACOS dest:reg, val:reg
ATAN dest:reg, val:reg
Take the inverse sine, cosine, or tangent of VAL and place the result (in
radians) into DEST.
- BITAND dest:reg, val1:reg, val2:reg
BITOR dest:reg, val1:reg, val2:reg
BITXOR dest:reg, val1:reg, val2:reg
BITNOR dest:reg, val1:reg, val2:reg
Perform the given bit-wise operation on VAL1 and VAL2 and place the result
into DEST.
- BITNEG dest:reg, val:reg
Negate each bit in VAL. That is, flip each bit in VAL.
- LSH dest:reg, val:reg, by:reg
ASH dest:reg, val:reg, by:reg
Either logically or arithmetically shift VAL by BY bits to the left (or right
is BY is negative). Put the result in DEST.
INTERN_LIT val1, "foo"
