This simplifies resource management, and should improve performance for most use
cases.

Identified with misc-include-cleaner.

These types performed identical roles. Merging them simplifies interoperability
between JITLink and ORC APIs (allowing us to address a few FIXMEs).
|
|
This type has been moved up into the llvm::orc::shared namespace.
This type was originally put in the detail:: namespace on the assumption that
few (if any) LLVM source files would need to use it. In practice it has been
needed in many places, and will continue to be needed until/unless
OrcTargetProcess is fully merged into the ORC runtime.

This re-applies e32b1eee6aab52e2b7b75ee15e506b3e7dd30e68, which was reverted in
20675d8f7dab293172266fdde426c2173b5b3997 due to broken unit tests. This patch
includes fixes for the tests.

This reverts commit e32b1eee6aab52e2b7b75ee15e506b3e7dd30e68.
Reverting while I fix some broken unit 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."

This reverts commit bef55a2b47a938ef35cbd7b61a1e5fa74e68c9ed while I investigate
failures on some bots. Also reverts "[lli] Add ChildTarget dependence on

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.

Removing the 'ess' suffix improves the ergonomics without sacrificing clarity.
Since this class is likely to be used more frequently in the future it's worth
some short term pain to fix this now.

This was already the case, but the recent change (957334382cd1) altered
the behavior on some of our bots where __unw_add_dynamic_fde is not
found. This restores the prior behavior on Darwin while also retaining
the new behavior from that change.
|
|
libgcc and libunwind have different flavours of __register_frame. Both
flavours are already correctly handled, except that the code to handle
the libunwind flavour is guarded by __APPLE__. This change uses the
presence of __unw_add_dynamic_fde in libunwind instead to detect whether
libunwind is used, rather than hardcoding it as Apple vs. non-Apple.
Fixes PR44074.
Thanks to Albert Jin <albert.jin@gmail.com> and Chris Schafmeister
<chris.schaf@verizon.net> for identifying the problem.

Replace the existing WrapperFunctionResult type in
llvm/include/ExecutionEngine/Orc/Shared/TargetProcessControlTypes.h with a
version adapted from the ORC runtime's implementation.
Also introduce the SimplePackedSerialization scheme (also adapted from the ORC
runtime's implementation) for wrapper functions to avoid manual serialization
and deserialization for calls to runtime functions involving common types.

implementation.
This patch aims to improve support for out-of-process JITing using OrcV2. It
introduces two new class templates, OrcRPCTargetProcessControlBase and
OrcRPCTPCServer, which together implement the TargetProcessControl API by
forwarding operations to an execution process via an Orc-RPC Endpoint. These
utilities are used to implement out-of-process JITing from llvm-jitlink to
a new llvm-jitlink-executor tool.
This patch also breaks the OrcJIT library into three parts:
-- OrcTargetProcess: Contains code needed by the JIT execution process.
-- OrcShared: Contains code needed by the JIT execution and compiler
processes
-- OrcJIT: Everything else.
This break-up allows JIT executor processes to link against OrcTargetProcess
and OrcShared only, without having to link in all of OrcJIT. Clients executing
JIT'd code in-process should start linking against OrcTargetProcess as well as
OrcJIT.
In the near future these changes will enable:
-- Removal of the OrcRemoteTargetClient/OrcRemoteTargetServer class templates
which provided similar functionality in OrcV1.
-- Restoration of Chapter 5 of the Building-A-JIT tutorial series, which will
serve as a simple usage example for these APIs.
-- Implementation of lazy, cross-target compilation in lli's -jit-kind=orc-lazy
mode.
