Rename the function to reflect its correct behavior and to be consistent
with `Module::getOrInsertFunction`. This is also in preparation of
adding a new `Intrinsic::getDeclaration` that will have behavior similar
to `Module::getFunction` (i.e, just lookup, no creation).
This is an almost-final step in eliminating debug-intrinsics -- read more
about that here: https://llvm.org/docs/RemoveDIsDebugInfo.html . To
correctly update variable location information in the background when
inserting instructions, we need some information carried at runtime in
BasicBlock::iterator, hence deprecating pointer-insertion.
An immediate fix for any deprecation warnings is to call "getIterator"
on the insertion position pointer. If you intend on inserting at the start
of a block, use BB->begin() or similar methods to fetch the appropriate
iterator.
Fix the builds with LLVM_TOOL_LLVM_DRIVER_BUILD enabled.
LLVM_ENABLE_EXPORTED_SYMBOLS_IN_EXECUTABLES is not completely
compatible with export_executable_symbols as the later will be ignored
if the previous is set to NO.
Fix the issue by passing if symbols need to be exported to
llvm_add_exectuable so the link flag can be determined directly
without calling export_executable_symbols_* later.

Update the folder titles for targets in the monorepository that have not
seen taken care of for some time. These are the folders that targets are
organized in Visual Studio and XCode
(`set_property(TARGET <target> PROPERTY FOLDER "<title>")`)
when using the respective CMake's IDE generator.
* Ensure that every target is in a folder
* Use a folder hierarchy with each LLVM subproject as a top-level folder
* Use consistent folder names between subprojects
* When using target-creating functions from AddLLVM.cmake, automatically
deduce the folder. This reduces the number of
`set_property`/`set_target_property`, but are still necessary when
`add_custom_target`, `add_executable`, `add_library`, etc. are used. A
LLVM_SUBPROJECT_TITLE definition is used for that in each subproject's
root CMakeLists.txt.
At the moment, Clang is rather liberal in assuming that 0 (and by extension unqualified) is always a safe default. This does not work for targets that actually use a different value for the default / generic AS (for example, the SPIRV that obtains from HIPSPV or SYCL). This patch is a first, fairly safe step towards trying to clear things up by querying a modules' default AS from the target, rather than assuming it's 0, alongside fixing a few places where things break / we encode the 0 == DefaultAS assumption. A bunch of existing tests are extended to check for non-zero default AS usage.
The ExceptionDemo example was no longer compiling (since llvm 14 at
least). The PR makes the example work with the current API and also
transition from MCJIT to ORC.
Fixes#63702
The base class llvm::ThreadPoolInterface will be renamed
llvm::ThreadPool in a subsequent commit.
This is a breaking change: clients who use to create a ThreadPool must
now create a DefaultThreadPool instead.
Some maintenance on implementation and tests:
* Drop manual TargetMachineBuilder setup
* Drop addDebugSupport() in favor of Orc's enableDebuggerSupport()
* Check that debug support plugins append jit_code_entry
* Update and reduce sample input
https://github.com/llvm/llvm-project/pull/74764 reported that the
`lljit-with-remote-debugging` test fails on AArch64 hosts, because the
input IR file states arch x86_64 explicitly. In order to drop the target
triple we have to remove a check in the example implementation.
Not sure it's fully portable now, but at least it's better than before.
This removes `CreateMalloc` from `CallInst` and adds it to the `IRBuilderBase`
class.
We no longer needed the `Instruction *InsertBefore` and
`BasicBlock *InsertAtEnd` arguments of the `createMalloc` helper
function because we're using `IRBuilder` now. That's why I we also don't
need 4 `CreateMalloc` functions, but only two.

This will make it easy for callers to see issues with and fix up calls
to createTargetMachine after a future change to the params of
TargetMachine.
This matches other nearby enums.
For downstream users, this should be a fairly straightforward
replacement,

CYGWIN uses the same format of WIN32 for shared libraries.
As the comment says: "a shared library can't have undefined references", in this case CYGWIN must be handled like WIN32 by CMakeLists.txt, otherwise you will get several errors when linking because some symbols are undefined.
Attached patch fixes this issue and allows to complete the build process for those targets.

In preparation for removing the `#include "llvm/ADT/StringExtras.h"`
from the header to source file of `llvm/Support/Error.h`, first add in
all the missing includes that were previously included transitively
through this header.
This reapplies 85c649bc02a, which was reverted in 35767e43d62 due to failures
with some example programs. The fix was to add export_executable_symbols to the
example programs.
This reapplies 371cb1af61d, which was reverted in 0b2240eda01 due to bot
failures.
The clang-repl test failure is fixed by dropping the process symbols definition
generator that was manually attached to the main JITDylib, since LLJIT now
exposes process symbols by default. (The bug was triggered when JIT'd code used
the process atexit provided by the generator, rather than the JIT atexit which
has been moved into the platform JITDylib).
Any LLJIT clients that see crashes in static destructors should likewise remove
any process symbol generators attached to their main JITDylib.
Configure the plugin to automatically call the debugger rendezvous breakpoint `__jit_debug_register_code()` for every translation unit (enabled) or never at all (disabled). Default API and behavior remain unchanged.
If AutoRegisterCode is turned off, it's the client's own responsibility to call the rendezvous breakpoint function at an appropriate time.
Depending on the complexity of the debugger's rendezvous breakpoint implementation, this can provide significant performance improvements in cases where many debug objects are added in sequence.

ExecutorAddr was introduced in b8e5f918166 as an eventual replacement for
JITTargetAddress. ExecutorSymbolDef is introduced in this patch as a
replacement for JITEvaluatedSymbol: ExecutorSymbolDef is an (ExecutorAddr,
JITSymbolFlags) pair, where JITEvaluatedSymbol was a (JITTargetAddress,
JITSymbolFlags) pair.
A number of APIs had already migrated from JITTargetAddress to ExecutorAddr,
but many of ORC's internals were still using the older type. This patch aims
to address that.
Some public APIs are affected as well. If you need to migrate your APIs you can
use the following operations:
* ExecutorAddr::toPtr replaces jitTargetAddressToPointer and
jitTargetAddressToFunction.
* ExecutorAddr::fromPtr replace pointerToJITTargetAddress.
* ExecutorAddr(JITTargetAddress) creates an ExecutorAddr value from a
JITTargetAddress.
* ExecutorAddr::getValue() creates a JITTargetAddress value from an
ExecutorAddr.
JITTargetAddress and JITEvaluatedSymbol will remain in JITSymbol.h for now, but
the aim will be to eventually deprecate and remove these types (probably when
MCJIT and RuntimeDyld are deprecated).
LLJIT needs access to symbols (e.g. llvm_orc_registerEHFrameSectionWrapper)
that will be defined in the executable when LLVM is linked statically.
Should fix https://github.com/llvm/llvm-project/issues/61712.
