Struct ReadOnly 

pub struct ReadOnly<'a> { /* private fields */ }

Where a pass puts the tables it asks for, until the pipeline takes them.

Implementations

impl<'a> ReadOnly<'a>

pub fn new( names: &'a mut Interner, taken: &'a HashSet<Symbol>, pointer_bits: u32, next: u32, ) -> Self

A place for tables in a module where taken are the names already in use.

next is the number the next name is made from. The pipeline makes one of these for every function a pass runs over, so the count is handed in and read back out with ReadOnly::next, and two functions never get the same name.

pub const fn pointer_bits(&self) -> u32

The width of an address on the target, which is how wide an index into a table is made.

pub fn table(&mut self, ty: Type, cells: Vec<i128>) -> Symbol

Asks for a table and gets back the name to load from it by.

The name is gcc’s, CSWTCH. and a number, which nothing written in C can spell because of the dot and which reads the same in a disassembly of either compiler. A name the module already has is stepped over rather than trusted not to be there, since an asm label can spell anything.

pub const fn next(&self) -> u32

The number the next name will be made from.

pub fn into_tables(self) -> Vec<Table>

Every table asked for so far, in the order they were asked for.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
