The declarations of these functions are defined in `test/benchmark/include/hpvm.h`, which must be included in the program. 2. `opt` takes (`main.ll`) and invoke the GenHPVM pass on it, which converts the HPVM-C function calls to HPVM intrinsics. This generates the HPVM textual representation (`main.hpvm.ll`). 3. `opt` takes the HPVM textual representation (`main.hpvm.ll`) and invokes the following passes in sequence: - * BuildDFG: Converts the textual representation to the internal HPVM representation. - * LocalMem and DFG2LLVM_NVPTX: Invoked only when GPU target is selected. Generates the kernel module (`main.kernels.ll`) and the portion of the host code that invokes the kernel into the host module (`main.host.ll`). - * DFG2LLVM_X86: Generates either all, or the remainder of the host module (`main.host.ll`) depending on the chosen target. - * ClearDFG: Deletes the internal HPVM representation from memory. + * BuildDFG: Converts the textual representation to the internal HPVM representation. + * LocalMem and DFG2LLVM_NVPTX: Invoked only when GPU target is selected.
