Implementations

impl CodeMemory

pub fn new() -> Self

Create a new CodeMemory instance.

pub fn allocate_for_function(
    &mut self,
    func: &CompiledFunction
) -> Result<&mut [VMFunctionBody], String>

Allocate a continuous memory block for a single compiled function. TODO: Reorganize the code that calls this to emit code directly into the mmap region rather than into a Vec that we need to copy in.

pub fn allocate_for_compilation(
    &mut self,
    compilation: &Compilation
) -> Result<Box<[&mut [VMFunctionBody]]>, String>

Allocate a continuous memory block for a compilation.

pub fn publish(&mut self, isa: &dyn TargetIsa)

Make all allocated memory executable.

pub fn published_contains(&self, addr: usize) -> bool

Returns whether any published segment of this code memory contains addr.
