=== What ===
A giant pile of shaders from various apps, for whatever purpose. In
particular, we use it to capture assembly output of the shader
compiler for analysis of regressions in compiler behavior.
=== Capturing shaders ===
env MESA_GLSL=dump appname |& tee log
./split-to-files.py appname log
# clean up resulting files, as the parsing is just an assist, not actually
# complete.
$EDITOR shaders/appname/*
=== Running shaders ===
# We rely on piglit binaries to actually execute the shader code.
# Replace this path with wherever you actually built piglit.
ln -s $HOME/src/piglit/bin ./
# this relies on i965 driver debug output, hack it up for anything else.
./run.py |& tee new-run
# To run just a subset:
./run.py shaders/supertuxkart |& tee new-run
=== Analysis ===
./result.py old-run new-run
