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 . benchmark/binarytrees.txt (skipped)

• benchmark/fannkuchredux.txt (0.035s)
• benchmark/fasta.txt (0.034s)
• benchmark/mandelbrot.txt (0.360s) . benchmark/meteor.txt (skipped)
• benchmark/nbody.txt (0.036s)
• benchmark/spectralnorm.txt (0.150s) [+5|-0] (0.62s)

run slow tests

$ test/run-tests.py bench -v -s

• benchmark/binarytrees.txt (1.395s)
• benchmark/fannkuchredux.txt (0.041s)
• benchmark/fasta.txt (0.033s)
• benchmark/mandelbrot.txt (0.357s)
• benchmark/meteor.txt (4.369s)
• benchmark/nbody.txt (0.033s)
• benchmark/spectralnorm.txt (0.142s) [+7|-0] (6.38s)

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.
