Static bytecode simulator

Overview

SEA

Static bytecode simulator for creating dependency/dependant based experimental bytecode format for CPython.

Example

a = random()

if a >= 5.0:
    print('a is too big')
    a = 5.0
elif a <= 2.0:
    print('a is too small')
    a *= 2

for counter in range(int(a)):
    if counter > 4:
        print('up to 4')
        break
    
    print(counter)

print('done')

Would normally compile to this

However with basic SEA, it is getting compiled to this

python -m sea (click to expand)
$0 = LOAD_NAME('random')

$2 = STORE_NAME('a', $1)
$3 = LOAD_NAME('a')
$4 = LOAD_CONST(5.0)
$5 = COMPARE_OP('>=', $3, $4)
$6 = POP_JUMP_IF_FALSE(28, $5)
$7 = LOAD_NAME('print')
$8 = LOAD_CONST('a is too big')
$9 = CALL_FUNCTION(1, $7, $8)
$10 = POP_TOP($9)
$11 = LOAD_CONST(5.0)
$12 = STORE_NAME('a', $11)
$13 = JUMP_FORWARD(52)
$14 = LOAD_NAME('a')
$15 = LOAD_CONST(2.0)
$16 = COMPARE_OP('<=', $14, $15)
$17 = POP_JUMP_IF_FALSE(52, $16)
$18 = LOAD_NAME('print')
$19 = LOAD_CONST('a is too small')
$20 = CALL_FUNCTION(1, $18, $19)
$21 = POP_TOP($20)
$22 = LOAD_NAME('a')
$23 = LOAD_CONST(2)
$24 = INPLACE_MULTIPLY($22, $23)
$25 = STORE_NAME('a', $24)
$26 = LOAD_NAME('range')
$27 = LOAD_NAME('int')
$28 = LOAD_NAME('a')
$29 = CALL_FUNCTION(1, $27, $28)
$30 = CALL_FUNCTION(1, $26, $29)
$31 = GET_ITER($30)
$32 = FOR_ITER(98)
$33 = STORE_NAME('counter', $32)
$34 = LOAD_NAME('counter')
$35 = LOAD_CONST(4)
$36 = COMPARE_OP('>', $34, $35)
$37 = POP_JUMP_IF_FALSE(88, $36)
$38 = LOAD_NAME('print')
$39 = LOAD_CONST('up to 4')
$40 = CALL_FUNCTION(1, $38, $39)
$41 = POP_TOP($40)
$42 = POP_TOP($31)
$43 = JUMP_ABSOLUTE(98)
$44 = LOAD_NAME('print')
$45 = LOAD_NAME('counter')
$46 = CALL_FUNCTION(1, $44, $45)

$51 = CALL_FUNCTION(1, $49, $50)
$52 = POP_TOP($51)
$53 = LOAD_CONST(None)
$54 = RETURN_VALUE($53)

And with the IR mode, it even supports basic control flow operations accross blocks;
