[vaivaswatha]

The preamble final asm looks like this:

;; ASM: Final program
;; Program kind: Script
.program:
move $$tmp $pc
jmpf $zero i10
DATA_SECTION_OFFSET[0..32]
DATA_SECTION_OFFSET[32..64]
Metadata
lw   $$ds $$tmp i1
add  $$ds $$ds $$tmp

The preamble bytecode looks like this:

0x00000000 MOVE R60 $pc                                    ;; [26, 240, 48, 0]
0x00000004 JMPF $zero 0xa                                  ;; [116, 0, 0, 10]
0x00000008                                                 ;; [0, 0, 0, 0, 0, 0, 2, 40]
