+# 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

Do you really need to set LD_LIBRARY_PATH just to do the 'make'?

Also, it would be super cool if you could figure out the magic to embed this
path in the pnacl-sz binary.

For some reason we do need the LD_LIBRARY_PATH even for make. I forget which
step it is, but there is one that fails without this.

I agree, it'd be better not to have to do this. Hopefully we can do this when we
figure out the right way to pull V8 into the system.

+```
+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

Done.

+subset. Running a subset will enable verbose output. You can download the
+torture tests from the [WebAssembly waterfall](https://wasm-stat.us/console).
