To compile: qmake-qt4 ; make Prerequisites: adb set up mali_compile compiled from my compile.c as /data/limare/compile To use: Drop a shader in the editor window. In the 'Subs' window, add a string-separated list of values, e.g. '0.0 1.0'. Wherever in the shader there is a $, it will be substituted with each value in turn. The 'args' line gets passed on to male_compile, so it's -v vertex or -f fragment shader. Hit 'Go'. In the Diff window there will be a side-by-side comparison of the shader binary with each input value. 'New diff' will spawn additional diff windows so you can look at the data in multiple ways at once.
