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<'a>(
&mut self,
func: &'a 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 publish(&mut self, isa: &dyn TargetIsa)

Make all allocated memory executable.

source

pub fn published_ranges<'a>(
&'a self
) -> impl Iterator<Item = (usize, usize )> + 'a

Returns all published segment ranges.
