Run regression tests for LLVM in AOSP

[Pavel Kosov]

Hello! 

I have a small question:

How do you guys run regression tests for LLVM in AOSP ? Is it possible at all (without hacking some scripts)?

For example: in standalone LLVM project running regression tests is very simple:

$: cd <path/where/your/llvm/was/built> 

$: ninja check-all

But how to do it for AOSP ? I mean - in which directory should I run "ninja check-all" ?

I tried to  run "ninja check-all"  in "out/stage1" and in "out/stage2" but without any luck. 

I've got next errors:
