This file is called
https://github.com/openjdk/leyden/blob/premain/src/hotspot/share/cds/cdsAccess.hpp
in the Leyden repo and provides an abstract API for accessing contents of the
AOT cache. In Leyden, we have APIs for accessing cached oops:
static int get_archived_object_permanent_index(oop obj)
NOT_CDS_JAVA_HEAP_RETURN_(-1);
static oop get_archived_object(int permanent_index)
NOT_CDS_JAVA_HEAP_RETURN_(nullptr);
and various pointer operations
static uint delta_from_shared_address_base(address addr);
template <typename T>
static void set_pointer(T** ptr, T* value) {
set_pointer((address*)ptr, (address)value);
}
static void set_pointer(address* ptr, address value);
Let's keep the AOTCacheAccess name for now and wait until we merge this PR down
to the Leyden repo. There's some overlap between AOTCacheAccess and CDSConfig.
Maybe we should do a refactor/rename later.
