This re-applies e32b1eee6aab52e2b7b75ee15e506b3e7dd30e68, which was reverted in
20675d8f7dab293172266fdde426c2173b5b3997 due to broken unit tests. This patch
includes fixes for the tests.
SPSExecutorAddr will now be serializable to/from ExecutorAddr, rather than
uint64_t. This improves type safety when working with serialized addresses.
Also updates the SupportFunctionCall to use an ExecutorAddrRange (rather than
a separate ExecutorAddr addr and uint64_t size field), and updates the
tpctypes::*Write data structures to use ExecutorAddr rather than
JITTargetAddress.
This reintroduces "[ORC] Introduce EPCGenericRTDyldMemoryManager."
(bef55a2b47a938ef35cbd7b61a1e5fa74e68c9ed) and "[lli] Add ChildTarget dependence
on OrcTargetProcess library." (7a219d801bf2c3006482cf3cbd3170b3b4ea2e1b) which were
reverted in 99951a56842d8e4cd0706cd17a04f77b5d0f6dd0 due to bot failures.
The root cause of the bot failures should be fixed by "[ORC] Fix uninitialized
variable." (0371049277912afc201da721fa659ecef7ab7fba) and "[ORC] Wait for
handleDisconnect to complete in SimpleRemoteEPC::disconnect."
(320832cc9b7e7fea5fc8afbed75c34c4a43287ba).
This reverts commit bef55a2b47a938ef35cbd7b61a1e5fa74e68c9ed while I investigate
failures on some bots. Also reverts "[lli] Add ChildTarget dependence on
OrcTargetProcess library." (7a219d801bf2c3006482cf3cbd3170b3b4ea2e1b) which was
a fallow-up to bef55a2b47a.
EPCGenericRTDyldMemoryMnaager is an EPC-based implementation of the
RuntimeDyld::MemoryManager interface. It enables remote-JITing via EPC (backed
by a SimpleExecutorMemoryManager instance on the executor side) for RuntimeDyld
clients.
The lli and lli-child-target tools are updated to use SimpleRemoteEPC and
SimpleRemoteEPCServer (rather than OrcRemoteTargetClient/Server), and
EPCGenericRTDyldMemoryManager for MCJIT tests.
By enabling remote-JITing for MCJIT and RuntimeDyld-based ORC clients,
EPCGenericRTDyldMemoryManager allows us to deprecate older remote-JITing
support, including OrcTargetClient/Server, OrcRPCExecutorProcessControl, and the
Orc RPC system itself. These will be removed in future patches.
