There was a problem hiding this comment.
Other than one very minor nit, LGTM. We should probably mirror this change across to the radsan branch, right? And, until RadsanBackend is merged upstream, probably wise to do it in upstream-radsan-v0 as well - what do you think?
Maybe you could do the cherry-picking and parent-project MR for realtime-sanitizer/radsan, and then I can kick off the docker release once it's merged?
Many thanks as always for your efforts on this!

This commit disables short string AddressSanitizer annotations on Apple platforms as a temporary solution to the problem reported in llvm#96099. For more information on Apple's block implementation, please refer to clang/docs/Block-ABI-Apple.rst [1]. The core issue lies in the fact that blocks are unaware of their content, causing AddressSanitizer errors when blocks are moved using `memmove`. I believe - and I'm not alone - that the issue should ideally be addressed within the block moving logic. However, this patch provides a temporary fix until a proper resolution exists in the Blocks runtime. [1]: https://github.com/llvm/llvm-project/blob/main/clang/docs/Block-ABI-Apple.rst

lldb today has two rules: When a thread stops at a BreakpointSite, we set the thread's StopReason to be "breakpoint hit" (regardless if we've actually hit the breakpoint, or if we've merely stopped *at* the breakpoint instruction/point and haven't tripped it yet). And second, when resuming a process, any thread sitting at a BreakpointSite is silently stepped over the BreakpointSite -- because we've already flagged the breakpoint hit when we stopped there originally. In this patch, I change lldb to only set a thread's stop reason to breakpoint-hit when we've actually executed the instruction/triggered the breakpoint. When we resume, we only silently step past a BreakpointSite that we've registered as hit. We preserve this state across inferior function calls that the user may do while stopped, etc. Also, when a user adds a new breakpoint at $pc while stopped, or changes $pc to be the address of a BreakpointSite, we will silently step past that breakpoint when the process resumes. This is purely a UX call, I don't think there's any person who wants to set a breakpoint at $pc and then hit it immediately on resuming. One non-intuitive UX from this change, but I'm convinced it is necessary: If you're stopped at a BreakpointSite that has not yet executed, you `stepi`, you will hit the breakpoint and the pc will not yet advance. This thread has not completed its stepi, and the thread plan is still on the stack. If you then `continue` the thread, lldb will now stop and say, "instruction step completed", one instruction past the BreakpointSite. You can continue a second time to resume execution. I discussed this with Jim, and trying to paper over this behavior will lead to more complicated scenarios behaving non-intuitively. And mostly it's the testsuite that was trying to instruction step past a breakpoint and getting thrown off -- and I changed those tests to expect the new behavior. The bugs driving this change are all from lldb dropping the real stop reason for a thread and setting it to breakpoint-hit when that was not the case. Jim hit one where we have an aarch64 watchpoint that triggers one instruction before a BreakpointSite. On this arch we are notified of the watchpoint hit after the instruction has been unrolled -- we disable the watchpoint, instruction step, re-enable the watchpoint and collect the new value. But now we're on a BreakpointSite so the watchpoint-hit stop reason is lost. Another was reported by ZequanWu in https://discourse.llvm.org/t/lldb-unable-to-break-at-start/78282 we attach to/launch a process with the pc at a BreakpointSite and misbehave. Caroline Tice mentioned it is also a problem they've had with putting a breakpoint on _dl_debug_state. The change to each Process plugin that does execution control is that 1. If we've stopped at a BreakpointSite that has not been executed yet, we will call Thread::SetThreadStoppedAtUnexecutedBP(pc) to record that. When the thread resumes, if the pc is still at the same site, we will continue, hit the breakpoint, and stop again. 2. When we've actually hit a breakpoint (enabled for this thread or not), the Process plugin should call Thread::SetThreadHitBreakpointSite(). When we go to resume the thread, we will push a step-over-breakpoint ThreadPlan before resuming. The biggest set of changes is to StopInfoMachException where we translate a Mach Exception into a stop reason. The Mach exception codes differ in a few places depending on the target (unambiguously), and I didn't want to duplicate the new code for each target so I've tested what mach exceptions we get for each action on each target, and reorganized StopInfoMachException::CreateStopReasonWithMachException to document these possible values, and handle them without specializing based on the target arch. rdar://123942164

…ehaviour differences between Clang and MSVC (llvm#99426) We have had quite a few issues created around how Clang treats intrinsics vs how MSVC treats intrinsics. While I was writing this I also added some sections on behaviour changes that caught me while porting my MSVC codebase to clang-cl. Hopefully we can point issues around intrinsics to this doc and hopefully it is useful to others who run into similar behaviour differences. The behaviour differences highlighted here are differences, as far as I am aware, that we do not intend to change or fix for MSVC.
This reverts commit 05f0e86. The debuginfo dexter tests are failing, probably because the way stepping over breakpoints has changed with my patches. And there are two API tests fails on the ubuntu-arm (32-bit) bot. I'll need to investigate both of these, neither has an obvious failure reason.
Bias doesn't change after startup. The test is enhanced for optimized sequences and atomic ops.
…-ftime-trace"" (llvm#99731) Reverts llvm#99545 There were a couple of issues reported in the PR: a sanitizer warning (https://lab.llvm.org/buildbot/#/builders/164/builds/1246/steps/14/logs/stdio) and a tmp file accidentally included in the commit.
This shall fix aarch64 builders.
When `cd %t` is used, it's conventional to move it above and omit `-o /dev/null`. We don't check the string before `warning:` since (a) the string is not very useful and (b) downstream might customize `ctx->e.logName` (argv[0]). count 0 is better than `--allow-empty`. In addition, without `2>&1` the previous test was effective.

… exception with pointer type by `void *` exception handler (llvm#99773) As in title, code which checks eligibility of exceptions with pointer types to be handled by exception handler of type `void *` disallowed this case. It was working like this: ```c++ if (isStandardPointerConvertible(ExceptionCanTy, HandlerCanTy) && isUnambiguousPublicBaseClass( ExceptionCanTy->getTypePtr()->getPointeeType().getTypePtr(), HandlerCanTy->getTypePtr()->getPointeeType().getTypePtr())) { ``` but in `isUnambiguousPublicBaseClass` there was code which looked for definitions: ```c++ bool isUnambiguousPublicBaseClass(const Type *DerivedType, const Type *BaseType) { const auto *DerivedClass = DerivedType->getCanonicalTypeUnqualified()->getAsCXXRecordDecl(); const auto *BaseClass = BaseType->getCanonicalTypeUnqualified()->getAsCXXRecordDecl(); if (!DerivedClass || !BaseClass) return false; ``` This code disallowed usage of `void *` type which was already correctly detected in `isStandardPointerConvertible`. AFAIK this seems like misinterpretation of specification: > 14.4 Handling an exception > a standard [pointer conversion](https://eel.is/c++draft/conv.ptr) not involving conversions to pointers to private or protected or ambiguous classes (https://eel.is/c++draft/except.handle#3.3.1) and > 7.3.12 Pointer conversions > ...

The slot addresses are not really correct (for fixed as well as scalable), but this prints something a little better with the limited information curently available.
This reverts commit f55b79f. The known issues with chained fixups have been addressed by llvm#98913, llvm#98305, llvm#97156 and llvm#95171. Compared to the original commit, support for xrOS (which postdates chained fixups' introduction) was added and an unnecessary test change was removed. ---------- Original commit message: Enable chained fixups in lld when all platform and version criteria are met. This is an attempt at simplifying the logic used in ld 907: https://github.com/apple-oss-distributions/ld64/blob/93d74eafc37c0558b4ffb88a8bc15c17bed44a20/src/ld/Options.cpp#L5458-L5549 Some changes were made to simplify the logic: - only enable chained fixups for macOS from 13.0 to avoid the arch check - only enable chained fixups for iphonesimulator from 16.0 to avoid the arch check - don't enable chained fixups for not specifically listed platforms - don't enable chained fixups for arm64_32

Added new headergen documentation.
Add example as unit test for creating a wrapper type/view for RankedTensorType with encoding. This view provides a more restricted & typed API while it allows one to avoid repeated casting queries and accessing the encoding directly. For users with more advance encodings, the expectation would be a separate attribute type, but here just StringAttr is used.
) Summary: This file is an object library, but uses the `LIBC_COPT_PUBLIC_PACKAING` option. This will always be undefined which leads to a type mismatch when uses actually try to link against it. This patch simply removes this and turns it into a header only library. This means that the implementations of the callback lists and the mutexes need to live in their respective files. The result is that `atexit` needs to be defined for `at_quick_exit` to be valid.
…it to avoid segfault in dlsym (llvm#98679) Follows llvm#98268 with a fix for a segfault during preinit on `ubuntu:20.04` environments. Previously, `rtsan` was not handling the situation where `dlsym` calls `calloc` during the interceptors initialization, resulting in a call to a function at a null address. @cjappl and I took inspiration from the solution in `nsan`, but we re-used the sanitizer internal allocator instead of our own static buffer. This PR also re-enables the existing non-instrumented `rtsan` tests for `x86_64` and `arm64` architectures. --------- Co-authored-by: Chris Apple <cja-private@pm.me>

… depobj construct (llvm#114221) A codegen crash is occurring when a depend object was initialized with omp_all_memory in the depobj directive. llvm#114214 The root cause of issue looks to be the improper handling of the dependency list when omp_all_memory was specified. The change introduces the use of OMPTaskDataTy to manage dependencies. The buildDependences function is called to construct the dependency list, and the list is iterated over to emit and store the dependencies. Reduced Test Case : ``` #include <omp.h> int main() { omp_depend_t obj; #pragma omp depobj(obj) depend(inout: omp_all_memory) } ``` ``` #1 0x0000000003de6623 SignalHandler(int) Signals.cpp:0:0 #2 0x00007f8e4a6b990f (/lib64/libpthread.so.0+0x1690f) #3 0x00007f8e4a117d2a raise (/lib64/libc.so.6+0x4ad2a) #4 0x00007f8e4a1193e4 abort (/lib64/libc.so.6+0x4c3e4) #5 0x00007f8e4a10fc69 __assert_fail_base (/lib64/libc.so.6+0x42c69) #6 0x00007f8e4a10fcf1 __assert_fail (/lib64/libc.so.6+0x42cf1) #7 0x0000000004114367 clang::CodeGen::CodeGenFunction::EmitOMPDepobjDirective(clang::OMPDepobjDirective const&) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x4114367) #8 0x00000000040f8fac clang::CodeGen::CodeGenFunction::EmitStmt(clang::Stmt const*, llvm::ArrayRef<clang::Attr const*>) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x40f8fac) #9 0x00000000040ff4fb clang::CodeGen::CodeGenFunction::EmitCompoundStmtWithoutScope(clang::CompoundStmt const&, bool, clang::CodeGen::AggValueSlot) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x40ff4fb) #10 0x00000000041847b2 clang::CodeGen::CodeGenFunction::EmitFunctionBody(clang::Stmt const*) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x41847b2) #11 0x0000000004199e4a clang::CodeGen::CodeGenFunction::GenerateCode(clang::GlobalDecl, llvm::Function*, clang::CodeGen::CGFunctionInfo const&) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x4199e4a) #12 0x00000000041f7b9d clang::CodeGen::CodeGenModule::EmitGlobalFunctionDefinition(clang::GlobalDecl, llvm::GlobalValue*) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x41f7b9d) #13 0x00000000041f16a3 clang::CodeGen::CodeGenModule::EmitGlobalDefinition(clang::GlobalDecl, llvm::GlobalValue*) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x41f16a3) #14 0x00000000041fd954 clang::CodeGen::CodeGenModule::EmitDeferred() (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x41fd954) realtime-sanitizer#15 0x0000000004200277 clang::CodeGen::CodeGenModule::Release() (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x4200277) realtime-sanitizer#16 0x00000000046b6a49 (anonymous namespace)::CodeGeneratorImpl::HandleTranslationUnit(clang::ASTContext&) ModuleBuilder.cpp:0:0 realtime-sanitizer#17 0x00000000046b4cb6 clang::BackendConsumer::HandleTranslationUnit(clang::ASTContext&) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x46b4cb6) realtime-sanitizer#18 0x0000000006204d5c clang::ParseAST(clang::Sema&, bool, bool) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x6204d5c) realtime-sanitizer#19 0x000000000496b278 clang::FrontendAction::Execute() (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x496b278) realtime-sanitizer#20 0x00000000048dd074 clang::CompilerInstance::ExecuteAction(clang::FrontendAction&) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x48dd074) realtime-sanitizer#21 0x0000000004a38092 clang::ExecuteCompilerInvocation(clang::CompilerInstance*) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x4a38092) realtime-sanitizer#22 0x0000000000fd4e9c cc1_main(llvm::ArrayRef<char const*>, char const*, void*) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0xfd4e9c) realtime-sanitizer#23 0x0000000000fcca73 ExecuteCC1Tool(llvm::SmallVectorImpl<char const*>&, llvm::ToolContext const&) driver.cpp:0:0 realtime-sanitizer#24 0x0000000000fd140c clang_main(int, char**, llvm::ToolContext const&) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0xfd140c) realtime-sanitizer#25 0x0000000000ee2ef3 main (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0xee2ef3) realtime-sanitizer#26 0x00007f8e4a10224c __libc_start_main (/lib64/libc.so.6+0x3524c) realtime-sanitizer#27 0x0000000000fcaae9 _start /home/abuild/rpmbuild/BUILD/glibc-2.31/csu/../sysdeps/x86_64/start.S:120:0 clang: error: unable to execute command: Aborted ``` --------- Co-authored-by: Chandra Ghale <ghale@pe31.hpc.amslabs.hpecorp.net>
