Read, parse and interpret Portable Native Client Executables (pexes).

See https://developers.google.com/native-client for more info about PNaCl.

Building

--------

To build debug (out/pnacl) and optimized builds (out/pnacl-opt-assert)::

  $ make

To build other various configurations::

  $ make everything

Tests

-----

To run tests::

  # Set your NACL_SDK_ROOT

  $ export NACL_SDK_ROOT=...

  $ make test

or run the Python test runner directly::

  # run all tests

  $ test/run-tests.py

  [+38|-0] (0.72s)

  # run tests that match a wildcard pattern

  $ test/run-tests.py bench -v

Benchmarks

----------

To run benchmarks::

  # Set your NACL_SDK_ROOT

  $ export NACL_SDK_ROOT=...

  $ test/run-benchmarks.py

  + benchmark/binarytrees.10.bench O0 (4.238s) (0.078s) (54.3x)

  + benchmark/binarytrees.10.bench O2 (4.238s) (0.070s) (60.4x)

  + benchmark/binarytrees.12.bench O0 (21.166s) (0.158s) (133.6x)

  + benchmark/binarytrees.12.bench O2 (21.166s) (0.116s) (182.4x)

  ...

  [+20|-0] (48.16s)

This runs the interpreter and compares it to a nexe translated using

pnacl-translate -O0 and -O2.
