We form VOPD instructions in the GCNCreateVOPD pass by combining back-to-back component instructions. There are strict register constraints for creating a legal VOPD, namely that the matching operands (e.g. src0x and src0y, src1x and src1y) must be in different register banks.

The copy operation with any side effect currently will have an implicit operand. It is good to have a separate opcode for such copy operations to distinguish them from the regular copies that have no side effects at all. This would allow targets to control the lowering for copies with side effects. AMDGPU, for instance, have the implicit dependency with exec register for all vector copies and no such dependency for scalar copies and there is a custom pass currently that adds the implicit exec operand to every vector copy and that doesn't look right. This patch introduces a new opcode PRED_COPY, called the predicated equivalent of the existing COPY opcode. Targets can define the default copy opcode and the `getCopyOpcode` callback would return the chosen opcode appropriately. Every interface that needs `TargetOpcode::COPY` should be replaced with a call to `getCopyOpcode`. Targets now get control over how and when to lower the PRED_COPY instructions.

This patch would enable the predicated copy opcode by default for AMDGPU right from the instruction selection. At certain point after regalloc, they will be fixed. When for SGPR copies they become regular COPY opcodes, for all vector copies, the implicit exec use will be added still retaining the PRED_COPY opcode. Based on the register class involved, later `copyPhysReg` called during expand post-RA pseudos will lower all forms of copy opcodes into respective target instructions.

To reduce the register pressure during allocation, when the allocator spills a virtual register that corresponds to a whole wave mode operation, the spill loads and restores should be activated for all lanes by temporarily flipping all bits in exec register to one just before the spills. It is not implemented in the compiler as of today and this patch enables the necessary support. This is a pre-patch before the SGPR spill to virtual VGPR lanes that would eventually causes the whole wave register spills during allocation. Change-Id: Ibae59323cc42555d2cbb992aea208a991c6da008

So far, we haven't exposed the allocation of whole-wave registers to regalloc. We hand-picked them for various whole wave mode operations. With a future patch, we want the allocator to efficiently allocate them rather than using the custom pre-allocation pass. Any liverange split of virtual registers involved in whole-wave operations require the resulting COPY introduced with the split to be performed for all lanes. It isn't implemented in the compiler yet. This patch would identify all such copies and manipulate the exec mask around them to enable all lanes without affecting the value of exec mask elsewhere. Change-Id: Iabdca7767fa718fd8cbefa6d21e6678db08633a1

Currently, the custom SGPR spill lowering pass spills SGPRs into physical VGPR lanes and the remaining VGPRs are used by regalloc for vector regclass allocation. This imposes many restrictions that we ended up with unsuccessful SGPR spilling when there won't be enough VGPRs and we are forced to spill the leftover into memory during PEI. The custom spill handling during PEI has many edge cases and often breaks the compiler time to time. This patch implements spilling SGPRs into virtual VGPR lanes. Since we now split the register allocation for SGPRs and VGPRs, the virtual registers introduced for the spill lanes would get allocated automatically in the subsequent regalloc invocation for VGPRs. Spill to virtual registers will always be successful, even in the high-pressure situations, and hence it avoids most of the edge cases during PEI. We are now left with only the custom SGPR spills during PEI for special registers like the frame pointer which is an unproblematic case. By spilling CSRs into virtual VGPR lanes, we might end up with broken CFIs that can potentially corrupt the frame unwinding in the debugger causing either a crash or a terrible debugging experience. This occurs when regalloc tries to spill or split the liverange of these virtual VGPRs. The CFIs should also be inserted at these intermediate points to correctly propagate the CFI entries. It is not currently implemented in the compiler. As a short-term fix, we continue to spill CSR SGPRs into physical VGPR lanes for the debugger to correctly compute the unwind information.

Liveness extention of virtual VGPRs used for SGPR spilling currently inserts a single KILL instruction in the epilogue blocks marking all of them collectively. This prevents their liveranges from being splittable during allocation and leads to unsuccessful allocation when ran out of allocatable registers. This patch introduces separate KILL instruction for each VGPR involved so that their liveness can be successfully splittable. Change-Id: I0e413177c0039d9606e6f88e7c83c7a283a3b3fb

The BitIntType has no getKind() method, so the FoldingSetID is taken from the APInt value representing the _BitInt(), similar to other methods in StmtProfile.cpp. Crash seen (summary form): clang-tidy: <src-root>/llvm/include/llvm/Support/Casting.h:566: decltype(auto) llvm::cast(const From&) [with To = clang::BuiltinType; From = clang::QualType]: Assertion `isa<To>(Val) && "cast<Ty>() argument of incompatible type!"' failed ``` #9 <address> decltype(auto) llvm::cast<clang::BuiltinType, clang::QualType>(clang::QualType const&) <src-root>/llvm/include/llvm/Support/Casting.h:566:3 #10 <address> clang::BuiltinType const* clang::Type::castAs<clang::BuiltinType>() const <bin-root>/tools/clang/include/clang/AST/TypeNodes.inc:86:1 #11 <address> (anonymous namespace)::StmtProfiler::VisitIntegerLiteral( clang::IntegerLiteral const*) <src-root>/clang/lib/AST/StmtProfile.cpp:1362:64 #12 <address> clang::StmtVisitorBase<llvm::make_const_ptr, (anonymous namespace)::StmtProfiler, void>::Visit(clang::Stmt const*) <src-root>/clang/include/clang/AST/StmtNodes.inc:1225:1 ``` Reviewed By: donat.nagy

…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 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 ??

This is a combination of multiple commits. This is the 1st commit message: DIOp-based DIExpression infrastructure Add the minimal support for DIOp-in-DIExpression, including DIOpFragment and DW_OP_LLVM_poisoned, and the API to differentiate the variants. This is the commit message #2: [Bitcode] Serialization for DIOp-based DIExpression This is the commit message #3: Dwarf generation for DIOp-based DIExpression This is a rather large patch with very minimal testing. It should probably be split up further, and more tests exercising every path are needed. This is the commit message #4: Extend clang option and add clang codegen for DIOp-based DIExpression This is the commit message #5: Support DIOp-based DIExpressions in SROA/mem2reg/instcombine This patch doesn't actually touch those passes, but just the utilities they use, namely createFragmentExpression(), and ConvertDebugDeclareToDebugValue(). This doesn't include assignment tracking, which has some special handling in SROA.cpp and PromoteMemoryToRegister.cpp. We're not planning on using dbg.assign for this (at least for the time being), so I just ignored that for now. This is the commit message #6: [HeterogeneousDwarf] Handle signed integers in DIOpShr and DIOpConvert This commit adds new DI operations to differentiate between a zext/sext DIOpConvert and a ashr/lshr DIOpShr. It isn't possible to use the IR type for this, since it doesn't distinguish between signed and unsigned integers. Fixes SWDEV-466183. This is the commit message #7: [Debugify] Add a flag to make DIOp-based DIExpressions This should be useful for porting debugify-based optimizer tests. Part of SWDEV-462843.

This is the commit message #10: [IRGen] Strip addrspacecasts when creating dbg.declares dbg.def does this in DIBuilder, but this commit just adds it to clang to avoid introducing a diff with upstream. This is the commit message #11: Verifier support for DIOp-based DIExpression Effectively a ported and updated version of https://gerrit-git.amd.com/c/lightning/ec/llvm-project/+/974933 Changed to one overload set rather than distinct method names for visitor base so the derived class can opt in to non-exhaustive visiting, rather than it be implied. Added a means to visit the result of the expression when it is otherwise valid (i.e. there is exactly one result). Moved as much of the validation as possible into the base class, leaving the only derived class using the visitor so far to essentially just do bitsize-based type checks when the arguments and/or DataLayout are available. The AsmPrinter support could be ported over to the visitor pattern eventually, and the verifier can be ported over to DIExpr, but these are left as future improvements. This is the commit message #12: Add DIOp AsmPrinter support for Convert/ZExt/SExt Since AsmPrinter currently require values on evaluation stack to be of generic type, we have to use the "legacy" dwarf-4 conversion operations. This can be a little verbose, particularly for sext. It would be technically possible to represent these with three DW_OP_converts (converting generic -> signed FromBits -> signed ToBits -> generic), but using the legacy version seemed simpler. In the future we could use DW_OP_convert to implement these, but in order to do that we would need to ensure that values on the dwarf evaluation stack have non-generic types. For instance, we would need to use use DW_OP_const_type instead of DW_OP_lit for constants. Failing to do so would break binary operators, which require compatible types for their inputs. One note: it seems like it's ambigious whether a DIOpArg that produces a negative signed value with a type smaller than the generic type will have it's higher order bits signed extended or not. For constants, FastISel produces a zero extended value, and non-fast ISel produces a sign extended value (see FastISel.cpp:1263 vs InstrEmitter:740 @ this commit). This can be observed by passing --fast-isel=false to the test file. SExt is correct for both cases, and always creates a fully sign-extended value of the generic type.

Several `FIXME(diexpression-poison)` comments mark places where there is additional work required still, e.g. workarounds or partial fixes to get changes passing PSDB.

… 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) #15 0x0000000004200277 clang::CodeGen::CodeGenModule::Release() (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x4200277) #16 0x00000000046b6a49 (anonymous namespace)::CodeGeneratorImpl::HandleTranslationUnit(clang::ASTContext&) ModuleBuilder.cpp:0:0 #17 0x00000000046b4cb6 clang::BackendConsumer::HandleTranslationUnit(clang::ASTContext&) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x46b4cb6) #18 0x0000000006204d5c clang::ParseAST(clang::Sema&, bool, bool) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x6204d5c) #19 0x000000000496b278 clang::FrontendAction::Execute() (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x496b278) #20 0x00000000048dd074 clang::CompilerInstance::ExecuteAction(clang::FrontendAction&) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x48dd074) #21 0x0000000004a38092 clang::ExecuteCompilerInvocation(clang::CompilerInstance*) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0x4a38092) #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) #23 0x0000000000fcca73 ExecuteCC1Tool(llvm::SmallVectorImpl<char const*>&, llvm::ToolContext const&) driver.cpp:0:0 #24 0x0000000000fd140c clang_main(int, char**, llvm::ToolContext const&) (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0xfd140c) #25 0x0000000000ee2ef3 main (/opt/cray/pe/cce/18.0.1/cce-clang/x86_64/bin/clang-18+0xee2ef3) #26 0x00007f8e4a10224c __libc_start_main (/lib64/libc.so.6+0x3524c) #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 <[email protected]>

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.

When generating `arm_neon.h`, NeonEmitter outputs code that violates strict aliasing rules (C23 6.5 Expressions ROCm#7, C++23 7.2.1 Value category [basic.lval] ROCm#11), for example: bfloat16_t __reint = __p0; uint32_t __reint1 = (uint32_t)(*(uint16_t *) &__reint) << 16; __ret = *(float32_t *) &__reint1; This patch fixed the offending code by replacing it with a call to `__builtin_bit_cast`.
