| A small tutorial on how to use the LLVM code generation tool: |
| |
| mkdir build |
| cd build |
| cmake -DTARGET_ARCH=[X64|WASM] ../ |
| make |
| |
| Suppose that your dart file is example/main.dart, then run: |
| pkg/vm/tool/release_llvm_precompiler example/main |
| This will generate a bunch of files in example/: |
| main.il -- the serialized IL |
| main.llvm -- the LLVM IR in text format |
| main.s -- the corresponding assembly |
| main.S -- the assembly from the Dart AOT pipeline |
| main.dill |
| main executable -- the executable from the Dart AOT pipeline |
| main.so -- the LLVM executable |
| |
| Then to run this: |
| ./out/ReleaseX64/dart_precompiled_runtime --llvm-mode example/main.so |
| |
| For Wasm running: |
| pkg/vm/tool/wasm_precompiler example/main |
| Produces a WebAssembly module main.wasm, among other things. |
