From 924dcd36ebed84f04729de05ec08b311a36a04c1 Mon Sep 17 00:00:00 2001 From: Richard-Qin-X Date: Sat, 1 Aug 2026 16:07:24 +0800 Subject: [CodeGen] Add target register descriptions Introduce an immutable register topology for units, subregisters, classes, banks, and preserved masks. Bind instruction descriptors to this topology through TargetDescription so builders, cloning, and verification share one target-aware contract. Add the test-only TestTarget model and positive and negative target fact coverage. --- backend/lib/CodeGen/MachineFunctionCloner.cpp | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'backend/lib/CodeGen/MachineFunctionCloner.cpp') diff --git a/backend/lib/CodeGen/MachineFunctionCloner.cpp b/backend/lib/CodeGen/MachineFunctionCloner.cpp index a8fe15e..d365fd0 100644 --- a/backend/lib/CodeGen/MachineFunctionCloner.cpp +++ b/backend/lib/CodeGen/MachineFunctionCloner.cpp @@ -15,6 +15,7 @@ #include "rcc/CodeGen/MachineOperand.h" #include "rcc/CodeGen/MachineRegisterInfo.h" #include "rcc/CodeGen/MachineVerifier.h" +#include "rcc/CodeGen/TargetDescription.h" #include "rcc/CodeGen/TargetFunctionState.h" #include @@ -553,9 +554,9 @@ MachineFunctionCloneResult::operator=(MachineFunctionCloneResult &&) noexcept = MachineFunctionCloneResult::~MachineFunctionCloneResult() = default; Expected cloneMachineFunction(const MachineFunction &Source, - const InstructionSet &Instructions, + const TargetDescription &Target, MachineFunctionCloneOptions Options) { - auto SourceVerification = MachineVerifier::verify(Source, Instructions); + auto SourceVerification = MachineVerifier::verify(Source, Target); if (!SourceVerification) return std::unexpected(SourceVerification.error()); if (!Options.NewStableID.isValid()) { @@ -615,7 +616,7 @@ Expected cloneMachineFunction(const MachineFunction return std::unexpected(CompilationStatus.error()); Result.ClonedFunction->compilationStatus() = std::move(*CompilationStatus); Result.ClonedFunction->properties() = Source.properties(); - auto DestinationVerification = MachineVerifier::verify(*Result.ClonedFunction, Instructions); + auto DestinationVerification = MachineVerifier::verify(*Result.ClonedFunction, Target); if (!DestinationVerification) return std::unexpected(DestinationVerification.error()); return Result; -- cgit v1.2.3
