__builtin_available() pulls in __isOSVersionAtLeast() from compiler-rt. Comment it out so we don't have to figure out how to pull in this symbol...

This gives numeric names to tuple fields, because lldb clients expect fields to have names, and because using plain numbers seemed most rust-like. Closes rust-lang#21

When `Target::GetEntryPointAddress()` calls `exe_module->GetObjectFile()->GetEntryPointAddress()`, and the returned `entry_addr` is valid, it can immediately be returned. However, just before that, an `llvm::Error` value has been setup, but in this case it is not consumed before returning, like is done further below in the function. In https://bugs.freebsd.org/248745 we got a bug report for this, where a very simple test case aborts and dumps core: ``` * thread #1, name = 'testcase', stop reason = breakpoint 1.1 frame #0: 0x00000000002018d4 testcase`main(argc=1, argv=0x00007fffffffea18) at testcase.c:3:5 1 int main(int argc, char *argv[]) 2 { -> 3 return 0; 4 } (lldb) p argc Program aborted due to an unhandled Error: Error value was Success.

CXXDeductionGuideDecl with a local typedef has its own copy of the TypedefDecl with the CXXDeductionGuideDecl as the DeclContext of that TypedefDecl. ``` template <typename T> struct A { typedef T U; A(U, T); }; A a{(int)0, (int)0}; ``` Related discussion on cfe-dev: http://lists.llvm.org/pipermail/cfe-dev/2020-November/067252.html Without this fix, when we import the CXXDeductionGuideDecl (via VisitFunctionDecl) then before creating the Decl we must import the FunctionType. However, the first parameter's type is the afore mentioned local typedef. So, we then start importing the TypedefDecl whose DeclContext is the CXXDeductionGuideDecl itself. The infinite loop is formed. ``` #0 clang::ASTNodeImporter::VisitCXXDeductionGuideDecl(clang::CXXDeductionGuideDecl*) clang/lib/AST/ASTImporter.cpp:3543:0 #1 clang::declvisitor::Base<std::add_pointer, clang::ASTNodeImporter, llvm::Expected<clang::Decl*> >::Visit(clang::Decl*) /home/egbomrt/WORK/llvm5/build/debug/tools/clang/include/clang/AST/DeclNodes.inc:405:0 rust-lang#2 clang::ASTImporter::ImportImpl(clang::Decl*) clang/lib/AST/ASTImporter.cpp:8038:0 rust-lang#3 clang::ASTImporter::Import(clang::Decl*) clang/lib/AST/ASTImporter.cpp:8200:0 rust-lang#4 clang::ASTImporter::ImportContext(clang::DeclContext*) clang/lib/AST/ASTImporter.cpp:8297:0 rust-lang#5 clang::ASTNodeImporter::ImportDeclContext(clang::Decl*, clang::DeclContext*&, clang::DeclContext*&) clang/lib/AST/ASTImporter.cpp:1852:0 rust-lang#6 clang::ASTNodeImporter::ImportDeclParts(clang::NamedDecl*, clang::DeclContext*&, clang::DeclContext*&, clang::DeclarationName&, clang::NamedDecl*&, clang::SourceLocation&) clang/lib/AST/ASTImporter.cpp:1628:0 rust-lang#7 clang::ASTNodeImporter::VisitTypedefNameDecl(clang::TypedefNameDecl*, bool) clang/lib/AST/ASTImporter.cpp:2419:0 rust-lang#8 clang::ASTNodeImporter::VisitTypedefDecl(clang::TypedefDecl*) clang/lib/AST/ASTImporter.cpp:2500:0 rust-lang#9 clang::declvisitor::Base<std::add_pointer, clang::ASTNodeImporter, llvm::Expected<clang::Decl*> >::Visit(clang::Decl*) /home/egbomrt/WORK/llvm5/build/debug/tools/clang/include/clang/AST/DeclNodes.inc:315:0 rust-lang#10 clang::ASTImporter::ImportImpl(clang::Decl*) clang/lib/AST/ASTImporter.cpp:8038:0 rust-lang#11 clang::ASTImporter::Import(clang::Decl*) clang/lib/AST/ASTImporter.cpp:8200:0 rust-lang#12 llvm::Expected<clang::TypedefNameDecl*> clang::ASTNodeImporter::import<clang::TypedefNameDecl>(clang::TypedefNameDecl*) clang/lib/AST/ASTImporter.cpp:165:0 rust-lang#13 clang::ASTNodeImporter::VisitTypedefType(clang::TypedefType const*) clang/lib/AST/ASTImporter.cpp:1304:0 rust-lang#14 clang::TypeVisitor<clang::ASTNodeImporter, llvm::Expected<clang::QualType> >::Visit(clang::Type const*) /home/egbomrt/WORK/llvm5/build/debug/tools/clang/include/clang/AST/TypeNodes.inc:74:0 rust-lang#15 clang::ASTImporter::Import(clang::QualType) clang/lib/AST/ASTImporter.cpp:8071:0 rust-lang#16 llvm::Expected<clang::QualType> clang::ASTNodeImporter::import<clang::QualType>(clang::QualType const&) clang/lib/AST/ASTImporter.cpp:179:0 rust-lang#17 clang::ASTNodeImporter::VisitFunctionProtoType(clang::FunctionProtoType const*) clang/lib/AST/ASTImporter.cpp:1244:0 rust-lang#18 clang::TypeVisitor<clang::ASTNodeImporter, llvm::Expected<clang::QualType> >::Visit(clang::Type const*) /home/egbomrt/WORK/llvm5/build/debug/tools/clang/include/clang/AST/TypeNodes.inc:47:0 rust-lang#19 clang::ASTImporter::Import(clang::QualType) clang/lib/AST/ASTImporter.cpp:8071:0 rust-lang#20 llvm::Expected<clang::QualType> clang::ASTNodeImporter::import<clang::QualType>(clang::QualType const&) clang/lib/AST/ASTImporter.cpp:179:0 rust-lang#21 clang::QualType clang::ASTNodeImporter::importChecked<clang::QualType>(llvm::Error&, clang::QualType const&) clang/lib/AST/ASTImporter.cpp:198:0 rust-lang#22 clang::ASTNodeImporter::VisitFunctionDecl(clang::FunctionDecl*) clang/lib/AST/ASTImporter.cpp:3313:0 rust-lang#23 clang::ASTNodeImporter::VisitCXXDeductionGuideDecl(clang::CXXDeductionGuideDecl*) clang/lib/AST/ASTImporter.cpp:3543:0 ``` The fix is to first create the TypedefDecl and only then start to import the DeclContext. Basically, we could do this during the import of all other Decls (not just for typedefs). But it seems, there is only one another AST construct that has a similar cycle: a struct defined as a function parameter: ``` int struct_in_proto(struct data_t{int a;int b;} *d); ``` In that case, however, we had decided to return simply with an error back then because that seemed to be a very rare construct.

…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.

`----------------------------- # 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#83886. This fixes a different crash but is related to llvm#46204. Backtrace: ``` #0 0x0000000000000000 in ??

… 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 rust-lang#2 0x00007f8e4a6b990f (/lib64/libpthread.so.0+0x1690f) rust-lang#3 0x00007f8e4a117d2a raise (/lib64/libc.so.6+0x4ad2a) rust-lang#4 0x00007f8e4a1193e4 abort (/lib64/libc.so.6+0x4c3e4) rust-lang#5 0x00007f8e4a10fc69 __assert_fail_base (/lib64/libc.so.6+0x42c69) rust-lang#6 0x00007f8e4a10fcf1 __assert_fail (/lib64/libc.so.6+0x42cf1) rust-lang#7 0x0000000004114367 clang::CodeGen::CodeGenFunction::EmitOMPDepobjDirective(clang::OMPDepobjDirective const&) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x4114367) rust-lang#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) rust-lang#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) rust-lang#10 0x00000000041847b2 clang::CodeGen::CodeGenFunction::EmitFunctionBody(clang::Stmt const*) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x41847b2) rust-lang#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) rust-lang#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) rust-lang#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) rust-lang#14 0x00000000041fd954 clang::CodeGen::CodeGenModule::EmitDeferred() (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x41fd954) rust-lang#15 0x0000000004200277 clang::CodeGen::CodeGenModule::Release() (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x4200277) rust-lang#16 0x00000000046b6a49 (anonymous namespace)::CodeGeneratorImpl::HandleTranslationUnit(clang::ASTContext&) ModuleBuilder.cpp:0:0 rust-lang#17 0x00000000046b4cb6 clang::BackendConsumer::HandleTranslationUnit(clang::ASTContext&) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x46b4cb6) rust-lang#18 0x0000000006204d5c clang::ParseAST(clang::Sema&, bool, bool) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x6204d5c) rust-lang#19 0x000000000496b278 clang::FrontendAction::Execute() (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x496b278) rust-lang#20 0x00000000048dd074 clang::CompilerInstance::ExecuteAction(clang::FrontendAction&) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x48dd074) rust-lang#21 0x0000000004a38092 clang::ExecuteCompilerInvocation(clang::CompilerInstance*) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x4a38092) rust-lang#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) rust-lang#23 0x0000000000fcca73 ExecuteCC1Tool(llvm::SmallVectorImpl<char const*>&, llvm::ToolContext const&) driver.cpp:0:0 rust-lang#24 0x0000000000fd140c clang_main(int, char**, llvm::ToolContext const&) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0xfd140c) rust-lang#25 0x0000000000ee2ef3 main (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0xee2ef3) rust-lang#26 0x00007f8e4a10224c __libc_start_main (/lib64/libc.so.6+0x3524c) rust-lang#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>

Two possible fixes are available: - Update calling conventions to properly support passing `f16` as integers. - Update `useFPRegsForHalfType()` to return `true` so that `f16` are still kept in `f32` registers, as before llvm#110199. This PR implements the first solution to not introduce any more ABI changes as llvm#110199 already did. As of what is the correct ABI for halfs, I don't think there is a correct answer. GCC doesn't support halfs on MIPS, and I couldn't find any information on old MIPS ABI manuals either.

Give names to tuple fields

7b4e719

This gives numeric names to tuple fields, because lldb clients expect fields to have names, and because using plain numbers seemed most rust-like. Closes rust-lang#21
