Provided Methods

fn malloc_align(&self, size: u64) -> Align

Returns the alignment that malloc would guarantee for requests of the given size.

fn emulate_allocator( &mut self, default: impl FnOnce(&mut MiriInterpCx<'mir, 'tcx>) -> InterpResult<'tcx> ) -> InterpResult<'tcx, EmulateItemResult>

Emulates calling the internal _rust* allocator functions

fn malloc( &mut self, size: u64, zero_init: bool ) -> InterpResult<'tcx, Pointer<Option<Provenance>>>

fn posix_memalign( &mut self, memptr: &OpTy<'tcx, Provenance>, align: &OpTy<'tcx, Provenance>, size: &OpTy<'tcx, Provenance> ) -> InterpResult<'tcx, Scalar<Provenance>>

fn free(&mut self, ptr: Pointer<Option<Provenance>>) -> InterpResult<'tcx>

fn realloc( &mut self, old_ptr: Pointer<Option<Provenance>>, new_size: u64 ) -> InterpResult<'tcx, Pointer<Option<Provenance>>>

fn aligned_alloc( &mut self, align: &OpTy<'tcx, Provenance>, size: &OpTy<'tcx, Provenance> ) -> InterpResult<'tcx, Pointer<Option<Provenance>>>
