pub struct CodeMemory { /* fields omitted */ }

Memory manager for executable code.

Implementations

impl CodeMemory

pub fn new() -> Self

Create a new CodeMemory instance.

pub fn allocate_functions<K>(
    &mut self,
    registry: &mut UnwindRegistry,
    compilation: &PrimaryMap<K, FunctionBody>
) -> Result<PrimaryMap<K, FunctionBodyPtr>, String> where
    K: EntityRef, 

Allocate a continuous memory block for a compilation.

Allocates memory for both the function bodies as well as function unwind data.

pub fn allocate_for_function(
    &mut self,
    registry: &mut UnwindRegistry,
    func: &FunctionBody
) -> 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_executable_custom_section(
    &mut self,
    section: &SectionBody
) -> Result<&mut [u8], String>

Allocate a continuous memory block for an executable custom section.

pub fn allocate_for_custom_section(
    &mut self,
    section: &SectionBody
) -> Result<&mut [u8], String>

Allocate a continuous memory block for a readable custom section.

pub fn publish(&mut self)

Make all allocated memory executable.
