Closing this issue, as the layered graph fusion extension at https://github.com/sommerlukas/llvm/blob/proposal/graph-fusion/sycl/doc/extensions/proposed/sycl_ext_oneapi_graph_fusion.asciidoc takes responsibility of this by providing properties to buffer accessors and USM allocations |

…tePluginObject After llvm/llvm-project#68052 this function changed from returning a nullptr with `return {};` to returning Expected and hitting `llvm_unreachable` before it could do so. I gather that we're never supposed to call this function, but on Windows we actually do call this function because `interpreter->CreateScriptedProcessInterface()` returns `ScriptedProcessInterface` not `ScriptedProcessPythonInterface`. Likely because `target_sp->GetDebugger().GetScriptInterpreter()` also does not return a Python related class. The previously XFAILed test crashed with: ``` # .---command stderr------------ # | PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace. # | Stack dump: # | 0.

`----------------------------- # error: command failed with exit status: 0xc000001d ``` That might be a bug on the Windows side, or an artifact of how our build is setup, but whatever it is, having `CreatePluginObject` return an error and the caller check it, fixes the failing test. The built lldb can run the script command to use Python, but I'm not sure if that means anything.

TestCases/Misc/Linux/sigaction.cpp fails because dlsym() may call malloc on failure. And then the wrapped malloc appears to access thread local storage using global dynamic accesses, thus calling ___interceptor___tls_get_addr, before REAL(__tls_get_addr) has been set, so we get a crash inside ___interceptor___tls_get_addr. For example, this can happen when looking up __isoc23_scanf which might not exist in some libcs. Fix this by marking the thread local variable accessed inside the debug checks as "initial-exec", which does not require __tls_get_addr. This is probably a better alternative to llvm/llvm-project#83886. This fixes a different crash but is related to llvm/llvm-project#46204. Backtrace: ``` #0 0x0000000000000000 in ??

When a graph is created by recording a queue with record & replay there is no way to tag memory objects internal to the graph, which would enable optimizations on the internal memory. Without this tagging, enabling kernel fusion on a graph created by record & replay may not be possible.
Such an interface must support both buffers and USM allocations.
