# 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
|
|
```
