…fine.parallel verifier
This patch updates AffineParallelOp::verify() to check each result type matches
its corresponding reduction op (i.e, the result type must be a `FloatType` if
the reduction attribute is `addf`)
affine.parallel will crash on --lower-affine if the corresponding result type
cannot match the reduction attribute.
```
%128 = affine.parallel (%arg2, %arg3) = (0, 0) to (8, 7) reduce ("maxf") -> (memref<8x7xf32>) {
%alloc_33 = memref.alloc() : memref<8x7xf32>
affine.yield %alloc_33 : memref<8x7xf32>
}
```
This will crash and report a type conversion issue when we run `mlir-opt --lower-affine`
```
Assertion failed: (isa<To>(Val) && "cast<Ty>() argument of incompatible type!"), function cast, file Casting.h, line 572.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.

…tePluginObject After llvm#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.

The concurrent tests all do a pthread_join at the end, and concurrent_base.py stops after that pthread_join and sanity checks that only 1 thread is running. On macOS, after pthread_join() has completed, there can be an extra thread still running which is completing the details of that task asynchronously; this causes testsuite failures. When this happens, we see the second thread is in ``` frame #0: 0x0000000180ce7700 libsystem_kernel.dylib`__ulock_wake + 8 frame #1: 0x0000000180d25ad4 libsystem_pthread.dylib`_pthread_joiner_wake + 52 frame #2: 0x0000000180d23c18 libsystem_pthread.dylib`_pthread_terminate + 384 frame #3: 0x0000000180d23a98 libsystem_pthread.dylib`_pthread_terminate_invoke + 92 frame #4: 0x0000000180d26740 libsystem_pthread.dylib`_pthread_exit + 112 frame #5: 0x0000000180d26040 libsystem_pthread.dylib`_pthread_start + 148 ``` there are none of the functions from the test file present on this thread. In this patch, instead of counting the number of threads, I iterate over the threads looking for functions from our test file (by name) and only count threads that have at least one of them. It's a lower frequency failure than the darwin kernel bug causing an extra step instruction mach exception when hardware breakpoint/watchpoints are used, but once I fixed that, this came up as the next most common failure for these tests. rdar://110555062

…ne symbol size as symbols are created (llvm#117079)" This reverts commit ba668eb. Below test started failing again on x86_64 macOS CI. We're unsure if this patch is the exact cause, but since this patch has broken this test before, we speculatively revert it to see if it was indeed the root cause. ``` FAIL: lldb-shell :: Unwind/trap_frame_sym_ctx.test (1692 of 2162) ******************** TEST 'lldb-shell :: Unwind/trap_frame_sym_ctx.test' FAILED ******************** Exit Code: 1 Command Output (stderr): -- RUN: at line 7: /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/lldb-build/bin/clang --target=specify-a-target-or-use-a-_host-substitution --target=x86_64-apple-darwin22.6.0 -isysroot /Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk -fmodules-cache-path=/Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/lldb-build/lldb-test-build.noindex/module-cache-clang/lldb-shell /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/llvm-project/lldb/test/Shell/Unwind/Inputs/call-asm.c /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/llvm-project/lldb/test/Shell/Unwind/Inputs/trap_frame_sym_ctx.s -o /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/lldb-build/tools/lldb/test/Shell/Unwind/Output/trap_frame_sym_ctx.test.tmp + /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/lldb-build/bin/clang --target=specify-a-target-or-use-a-_host-substitution --target=x86_64-apple-darwin22.6.0 -isysroot /Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk -fmodules-cache-path=/Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/lldb-build/lldb-test-build.noindex/module-cache-clang/lldb-shell /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/llvm-project/lldb/test/Shell/Unwind/Inputs/call-asm.c /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/llvm-project/lldb/test/Shell/Unwind/Inputs/trap_frame_sym_ctx.s -o /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/lldb-build/tools/lldb/test/Shell/Unwind/Output/trap_frame_sym_ctx.test.tmp clang: warning: argument unused during compilation: '-fmodules-cache-path=/Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/lldb-build/lldb-test-build.noindex/module-cache-clang/lldb-shell' [-Wunused-command-line-argument] RUN: at line 8: /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/lldb-build/bin/lldb --no-lldbinit -S /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/lldb-build/tools/lldb/test/Shell/lit-lldb-init-quiet /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/lldb-build/tools/lldb/test/Shell/Unwind/Output/trap_frame_sym_ctx.test.tmp -s /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/llvm-project/lldb/test/Shell/Unwind/trap_frame_sym_ctx.test -o exit | /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/lldb-build/bin/FileCheck /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/llvm-project/lldb/test/Shell/Unwind/trap_frame_sym_ctx.test + /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/lldb-build/bin/lldb --no-lldbinit -S /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/lldb-build/tools/lldb/test/Shell/lit-lldb-init-quiet /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/lldb-build/tools/lldb/test/Shell/Unwind/Output/trap_frame_sym_ctx.test.tmp -s /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/llvm-project/lldb/test/Shell/Unwind/trap_frame_sym_ctx.test -o exit + /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/lldb-build/bin/FileCheck /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/llvm-project/lldb/test/Shell/Unwind/trap_frame_sym_ctx.test /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/llvm-project/lldb/test/Shell/Unwind/trap_frame_sym_ctx.test:21:10: error: CHECK: expected string not found in input ^ <stdin>:26:64: note: scanning from here frame #1: 0x0000000100003ee9 trap_frame_sym_ctx.test.tmp`tramp ^ <stdin>:27:2: note: possible intended match here frame #2: 0x00007ff7bfeff6c0 ^ Input file: <stdin> Check file: /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake/llvm-project/lldb/test/Shell/Unwind/trap_frame_sym_ctx.test -dump-input=help explains the following input dump.

## Description This PR fixes a segmentation fault that occurs when passing options requiring arguments via `-Xopenmp-target=<triple>`. The issue was that the function `Driver::getOffloadArchs` did not properly parse the extracted option, but instead assumed it was valid, leading to a crash when incomplete arguments were provided. ## Backtrace ```sh llvm-project/build/bin/clang++ main.cpp -fopenmp=libomp -fopenmp-targets=powerpc64le-ibm-linux-gnu -Xopenmp-target=powerpc64le-ibm-linux-gnu -o PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
