Detailed Description

Definitions for the Fun VM bytecode: opcodes, instruction format, and bytecode container API.

This header declares the VM's operation codes (OpCode), the compact instruction representation (Instruction), and the owning bytecode container (Bytecode) together with minimal constructor/manipulation helpers. The concrete execution semantics for each opcode are implemented in the VM (see vm.c and vm/* handlers).

Definition in file bytecode.h.

Typedef Documentation

◆ Bytecode

typedef struct Bytecode Bytecode

Enumeration Type Documentation

◆ OpCode

enum OpCode

VM operation codes executed by the Fun virtual machine.

Unless stated otherwise, opcodes operate on the VM stack. Comments on each opcode describe stack effects using a left-to-right pop order and the value pushed as a result. For example, "pops b, a; pushes a+b" means the instruction will pop first b then a from the stack and finally push the result of a+b.

Function Documentation

◆ bytecode_add_constant()

int bytecode_add_constant	(	Bytecode *	bc,
		Value	v )

Append a constant to a Bytecode's constant table.

The value is deep-copied into the table; the caller retains ownership of v and may free it independently.

Parameters

bc	Target bytecode (must not be NULL).
v	Value to store (copied).

Returns: The index of the stored constant (zero-based).

Definition at line 48 of file bytecode.c.

Here is the caller graph for this function:

◆ bytecode_add_instruction()

int bytecode_add_instruction	(	Bytecode *	bc,
		OpCode	op,
		int32_t	operand )

Append a single instruction to the instruction stream.

Parameters

bc	Target bytecode (must not be NULL).
op	Opcode to emit.
operand	Operand value (semantics depend on opcode).

Returns: The index of the emitted instruction (zero-based).

Definition at line 62 of file bytecode.c.

Here is the caller graph for this function:

◆ bytecode_dump()

void bytecode_dump ( const Bytecode * bc )

Print a human-readable dump of constants and instructions to stdout.

Intended for debugging and tests. Formats constants with print_value() and shows each instruction index, mnemonic and operand.

Parameters

bc	Bytecode to dump (prints "<null bytecode>" if NULL).

Definition at line 423 of file bytecode.c.

Here is the call graph for this function:

Here is the caller graph for this function:

◆ bytecode_free()

void bytecode_free ( Bytecode * bc )

Free a Bytecode and all memory it owns.

Frees constants (deep), instruction array, and metadata strings. Accepts NULL and is then a no-op.

Parameters

bc	Bytecode to free (may be NULL).

Definition at line 92 of file bytecode.c.

Here is the call graph for this function:

Here is the caller graph for this function:

◆ bytecode_new()

Bytecode * bytecode_new ( void )

Allocate and initialize an empty Bytecode object.

Initializes instruction and constant arrays to empty and clears metadata. Caller owns the returned pointer and must free it with bytecode_free().

Returns: Newly allocated Bytecode*, or NULL on allocation failure.

Definition at line 27 of file bytecode.c.

Here is the caller graph for this function:

◆ bytecode_set_operand()

void bytecode_set_operand	(	Bytecode *	bc,
		int	idx,
		int32_t	operand )

Patch the operand of a previously emitted instruction.

Silently ignores out-of-bounds indices.

Parameters

bc	Target bytecode.
idx	Instruction index to patch.
operand	New operand value.
