[RAZR HD Original Android Development] skeevydude:
I'm gonna guess the 2nd one is A9 based on the IO readout.

All the optimizations are done, I just have to finish the guide with how I did it all. With the PAC build script in my repos, it's possible to choose between Os, O2, O3, Archidroid O3, and Archidroid Ofast when compiling PAC. Just add in my local manifest after the first, initial, sync completes, then sync again.

The build is using Google GCC 4.8 (and replaces Google GCC 4.7 with Archi/Linaro 4.7, though it's unused by default).

Based on what you posted, I'm gonna tweak android_build to use A15 for Krait over A9 which is currently in place. I'll have two builds posted tomorrow -- one build with Archi O3 and the other with Ofast, only no one will no which is which. Gonna do the A15, update my forks if needed, start the first of two builds without syncing, and call it a night. I'm tired, worked 10 hours today, got home, and I've been doing this, playing with my dogs, and getting things done around the house....I can't believe it's 10 past 11pm already :crying: Today went by way too fast.

EDIT: Kept getting weird build errors with Google GCC 4.8; switched to Archi 4.7; starting again; really calling it a night this time (if the build goes more than 10 minutes :cowboy:)

EDIT2: I think I screwed up cherry-picking android_build (easy for cm, complicated for PAC).... or could also be a ccache error...Gonna figure it out tomorrow.

And you know you're tired when you do a change to android build, open the terminal, cd to vendor/pac, try to commit and push the change, multiple times over 15 minutes going wtf???, when you finally realize you're in the wrong directory....
