Function mmtk::util::malloc::realloc_with_old_size

pub fn realloc_with_old_size<VM: VMBinding>(
    mmtk: &MMTK<VM>,
    addr: Address,
    size: usize,
    old_size: usize
) -> Address

Reallocate the given area of memory. Similar to libc’s realloc. This also adjusts the allocated memory size based on the original allocation and the new allocation, and counts that into the heap size for the given MMTk instance.
