| # Wasm Prototype Experiment Notes |
| |
| Here's the command I use to test: |
| |
| ``` |
| LD_LIBRARY_PATH=~/nacl/v8/out/native/lib.target make -j48 \ |
| -f Makefile.standalone WASM=1 && \ |
| LD_LIBRARY_PATH=~/nacl/v8/out/native/lib.target ./pnacl-sz -O2 -filetype=asm \ |
| -target=arm32 ./torture-s2wasm-sexpr-wasm/20000112-1.c.s.wast.wasm |
| ``` |
| |
| You'll probably need to adjust your `LD_LIBRARY_PATH` to point to where your v8 |
| libraries are. |
| |
| You'll need to build v8 as a shared library. Build it like this: |
| |
| ``` |
| make -j48 native component=shared_library |
| ``` |
| |
| `wasm-run-torture-tests.py` can be used to run all the tests, or some |
| subset. Running a subset will enable verbose output. You can download the |
| torture tests from the [WebAssembly waterfall](https://wasm-stat.us/console) or |
| by running `./fetch-torture-tests.sh`. |
| |
| |
| To compile and run an executable, do the following from the subzero directory. |
| |
| ``` |
| ./pnacl-sz -filetype=obj -o foo.o foo.wasm |
| clang -m32 foo.o src/wasm-runtime.c |
| ./a.out |
| ``` |
| |
| Other useful commands: |
| |
| Compile a C file to a .wasm |
| ``` |
| ./wasm-install/bin/emscripten/emcc hello-wasm.c -s BINARYEN=1 |
| ./wasm-install/bin/sexpr-wasm a.out.wast -o a.out.wasm |
| ``` |
