Struct CodeMemory

Source

pub struct CodeMemory { /* private fields */ }

Expand description

Memory manager for executable code.

Implementations§

Source §

impl CodeMemory

Source

pub fn new() -> Self

Create a new CodeMemory instance.

Source

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.

Source

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

Allocate a continuous memory block for a compilation.

Source

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

Make all allocated memory executable.

Source

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

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