Struct Irgen

pub struct Irgen {
    decls: BTreeMap<String, Declaration>,
    typedefs: HashMap<String, Dtype>,
    structs: HashMap<String, Option<Dtype>>,
    struct_tempid_counter: usize,
}

A C file going through IR generation.

Fields

decls: BTreeMap<String, Declaration>

Declarations made in the C file (e.g, global variables and functions)

typedefs: HashMap<String, Dtype>

Type definitions made in the C file (e.g, typedef my_type = int;)

structs: HashMap<String, Option<Dtype>>

Structs defined in the C file,

struct_tempid_counter: usize

Temporary counter for anonymous structs. One should not need to use this any more.

Implementations

impl Irgen

const BID_INIT: BlockId

const BID_COUNTER_INIT: usize = 1usize

const TEMPID_COUNTER_INIT: usize = 0usize

fn add_declaration(&mut self, source: &Declaration) -> Result<(), IrgenError>

Add a declaration. It can be either a struct, typedef, or a variable.

fn add_function_definition( &mut self, source: &FunctionDefinition, ) -> Result<(), IrgenError>

Add a function definition.

fn add_decl(&mut self, name: &str, decl: Declaration) -> Result<(), IrgenError>

Adds a possibly existing declaration.

Returns error if the previous declearation is incompatible with decl.

impl Default for Irgen

fn default() -> Irgen

Returns the “default value” for a type.
