+# ComBack++: A Multi-Language Dataset Providing End-to-End Support for Compiler Backend Development
+
+ComBack++ is a large-scale, multi-platform and multi-language compiler backend code dataset. It is sourced from GCC and LLVM backends corresponding to 183 target platforms.
+

+- Tasks
+  - Statement-Level Completion: complete current statement.
+  ```c++
+  //Inputs:
+  ...
+  adjustReg(MBB,LastFrameDestroy, DL, SPReg, FPReg, -StackSize+RVFI->getVarArgsSaveSize() 
+  //Ground Truth:
+  MachineInstr::FrameDestroy);
+  ```
+
+  - Next-Statement Suggestion: predict the next statement.
+
+   ```c++
+  //Inputs:
+  ...
+  maxCallFrameSize = (maxCallFrameSize + AlignMask) & ~AlignMask;
+  //Ground Truth:
+  MFI -> setMaxCallFrameSize(maxCallFrameSize);
+  ```
+
+
+  - Code Generation: generate a function template with function description in natrual language.
+
+   ```c++
+  //Inputs:
+  getPointerRegClass: Returns a TargetRegisterClass used for pointer values.
+  //Ground Truth:
+  TargetRegisterClass *RegisterInfo::getPointerRegClass(MachineFunction &MF ,unsigned Kind) {
+      return Subtarget.is64Bit() ? <ISA_LIT> : <ISA_LIT>;
+  }
+  ```
+
+  - Program Repair: automatically fixing bugs at identified locations.
+
+   ```c++
+  //Inputs:
+  int64_t Imm; <BUGS> MCExpr::VariantKind VK; <BUGE> ...
+  //Ground Truth:
+  <FIXS> MCExpr::VariantKind VK = MCExpr::VK_None; <FIXE>
+  ```
+
+## Organization
+
+
+
+- `./*.jsonl`: **Take data of RISC-V,ARC,NVPTX both in GCC and LLVM as test set, split train/valid set in the ratio of 90%:10% of other targets excluding RI5CY(RI5CY is custmoized based on RISCV)**
