Android 4.3 and Updated Developer Tools

Today in San Francisco we announced Android 4.3, a sweeter version of Jelly Bean that includes great new features for users and developers. Android 4.3 powers the new Nexus 7 tablet that's coming soon to Google Play and retail outlets, and it's rolling out now as an update to Nexus 4, Nexus 7, Nexus 10, and Galaxy Nexus HSPA+ devices across the world.

For developers, Android 4.3 includes the latest performance enhancements to keep your apps fast, smooth, and efficient, together with new APIs and capabilities to use in your apps. Here's a taste of what's new:

    OpenGL ES 3.0 — Game developers can now take advantage of OpenGL ES 3.0 and EGL extensions as standard features of Android, with access from either framework or native APIs.
...

Quick test on old Nexus 7 (Tegra 3)

Google put some new tricks into the system to prevent root access.
Chainfire's experimental SuperSU does the job.

Trinity OC kernel and CWM 6.031 recovery work fine.

I found some interesting files in bin folder, i have no idea though how to uncompress/decrypt *.bc files 
libclcore_debug.bc
libclcore_neon.bc
libclcore.bc

But WTF? libGLESv3.so is only a copy of libGLESv2.so

Quick test with Nexus 4

SuperSU 1.43 and CWM recovery 6.034 work fine.
Trinity OC kernel TF133 fails to boot. I can live the hot summer w/o overclocking until it's fixed.

Here also libGLESv3.so and libGLESv2.so are identical, can anyone shed a light on that?
However OpenGL-ES Info shows up GLES v3

I think Android 4.3 might be trying to add support for OpenCL. Khronos announced an Android OpenCL driver interface at SIGGRAPH.

My HTC One already has a libopencl but it is hard to use without the driver interface.

I expect the next version of Android to fully support OpenCL hopefully with a Java interface too.

On my Nexus 4 i had libopencl in JB4.2, but it has been removed in 4.3
In case of need Adreno version can be downloaded >here<.

Regarding the aforementioned *.bc files, i have now word that they are part of "renderscript".
I'm still curious why they are unreadable.
