[ORC] Update ELF debugger support plugin to use AllocActions (#167866)

2025-11-17T08:33:03+00:00

The `DebugObjectManagerPlugin` implements debugger support for ELF
platforms with the GDB JIT Interface. It emits a separate debug object
allocation in addition to the LinkGraph's own allocation. This used to
happen in the plugin's `notifyEmitted()` callback, i.e. after the
LinkGraph's allocation was finalized. In the meantime, it had to block
finalization of the corresponding materialization unit to make sure that
the debugger can register the object before the code runs.

This patch switches the plugin to use an allocation action instead. We
can remove the `notifyEmitted()` hook and implement all steps as JITLink
passes.

[ORC] Drop EHFrameRegistrar, register eh-frames with AllocActions (#130719)

2025-03-11T23:02:30+00:00

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

[ORC] Use EPC bootstrap symbols to communicate eh-frame registration fn addrs.

2023-08-23T21:19:12+00:00

By using bootstrap symbols to communicate these addresseses, rather than dlsym
lookups, we no longer need them to be exported from the main executable. On ELF,
where symbols aren't exported from the main executable by default, this
eliminates a common source of missing symbol errors and allows for smaller
executables (if exports from the main executable aren't otherwise needed and
can be removed).

[ORC] Add a generic bootstrap key-value store to SimpleRemoteEPC.

2023-04-02T17:27:06+00:00

SimpleRemoteEPC already included a "bootstrap symbols map" that could be used
to communicate the addresses of symbols needed for JIT bootstrap. The new
bootstrap map can be used to communicate arbitrary bootstrap values (encoded as
SPS buffers).

The bootstrap symbols map is kept as distinct becasue bootstrap symbols are
significant, and having a known value type for them allows for better debug
logging (we know how to render the values) and tooling (e.g. utils for adding
all bootstrap symbols to a JITDylib).

[ORC] Remove more unnecessary ExecutorAddr::getValue calls.

[NFC][TargetParser] Replace uses of llvm/Support/Host.h

2023-02-10T09:59:46+00:00

The forwarding header is left in place because of its use in
`polly/lib/External/isl/interface/extract_interface.cc`, but I have
added a GCC warning about the fact it is deprecated, because it is used
in `isl` from where it is included by Polly.

[ORC] Move CWrapperFunctionResult out of the detail:: namespace.

2021-10-30T23:12:45+00:00

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.
