Defold Shaders (2021 shader practice / learning edition)

Modified version of the editor script which appears to work with the stand alone legacy version download (tested Mali Offline Compiler Version 6.4 Windows 64-bit).

I think removing the .exe should make it work on other platforms too.

Now I will need to learn how to use this to optimize shaders.

No driver specified, using "Mali-Gxx_r11p0-00rel0" as default.

No core revision specified, using "r0p3" as default.


64 work registers used, 2 uniform registers used, spilling not used.

			A	L/S	T
Instructions Emitted:	5	4	1
Shortest Path Cycles:	5	4	1
Longest Path Cycles:	5	4	1

A = Arithmetic, L/S = Load/Store, T = Texture
Note: The cycles counts do not include possible stalls due to cache misses.
Note: Shaders with loops may return "N/A" for cycle counts if the number of cycles cannot be statically determined.

Compilation succeeded.
