From a8a9d7d926202450645deae872d4d9dc11d63215 Mon Sep 17 00:00:00 2001 From: Richard-Qin-X Date: Sun, 2 Aug 2026 03:37:46 +0800 Subject: [CodeGen] Model machine debug metadata Replace marker-based metadata operands with scoped references and inline DIExpression values. Add structured DILocation chains, instruction debug attachments, stack variable records, and entry values with unified verification, builder support, and deterministic cloning. --- backend/lib/CodeGen/MachineOperand.cpp | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) (limited to 'backend/lib/CodeGen/MachineOperand.cpp') diff --git a/backend/lib/CodeGen/MachineOperand.cpp b/backend/lib/CodeGen/MachineOperand.cpp index 0e5febd..cd2d217 100644 --- a/backend/lib/CodeGen/MachineOperand.cpp +++ b/backend/lib/CodeGen/MachineOperand.cpp @@ -158,11 +158,12 @@ Expected MachineOperand::registerMask(std::shared_ptr MachineOperand::metadata(std::string Marker, std::uint32_t TargetFlags) { - if (Marker.empty()) { - return makeUnexpected(ErrorCode::InvalidArgument, "metadata operand marker cannot be empty"); +Expected MachineOperand::metadata(MachineMetadataValue Value, + std::uint32_t TargetFlags) { + if (!Value.isValid()) { + return makeUnexpected(ErrorCode::InvalidArgument, "metadata operand value must be valid"); } - return MachineOperand(Kind::Metadata, MetadataOperand{std::move(Marker)}, TargetFlags); + return MachineOperand(Kind::Metadata, MetadataOperand{std::move(Value)}, TargetFlags); } MachineOperand MachineOperand::targetIndex(TargetIndex Index, std::int64_t Offset, -- cgit v1.2.3
