Struct BytecodeLoader

pub struct BytecodeLoader<R: Read> {
    pub function_map: HashMap<Option<String>, Gs2BytecodeAddress>,
    pub instructions: Vec<Instruction>,
    pub block_address_to_function: HashMap<Gs2BytecodeAddress, Option<String>>,
    /* private fields */
}

A structure for loading bytecode from a reader.

Fields

function_map: HashMap<Option<String>, Gs2BytecodeAddress>

A map of function names to their addresses.

instructions: Vec<Instruction>

The instructions in the module.

block_address_to_function: HashMap<Gs2BytecodeAddress, Option<String>>

A map of block start addresses to their corresponding function name.

Implementations

impl<R: Read> BytecodeLoader<R>

pub fn get_function_name_for_address( &self, address: Gs2BytecodeAddress, ) -> Result<Option<String>, BytecodeLoaderError>

Get the function name for a given address.

Arguments

• address: The address to get the function name for.

Returns

• The function name, if it exists.

Errors

• BytecodeLoaderError::UnreachableBlock if the block is unreachable, and therefore, the function name cannot be determined.

pub fn is_instruction_reachable(&self, address: Gs2BytecodeAddress) -> bool

Checks if an instruction is reachable.

Arguments

• address: The address to check.

Returns

• true if the instruction is reachable, false otherwise.

pub fn find_block_start_address( &self, address: Gs2BytecodeAddress, ) -> Gs2BytecodeAddress

Helper function to figure out what block the address is in. This basically looks at the argument, and finds the closest block start address that is less than or equal

Arguments

• address: The address to find the block for.

Returns

• The block start address.
