Hi,

llvm version used in android marshmallow-x86 is 3.7.0 (preceding the R600 to
AMDGPU target renaming).
On android my options are currently limited to backporting latest patches on
top llvm 3.7.0 or trying upgrade to latest llvm 3.7.x doing some AMDGPU target
porting of android makefiles.

>'nosb' option will have no effect, it applies to r600 only

Are there other options that could help to workaround the issue
or for debugging purposes?

I'll check if some control flow lowering bug was reported,
in order to apply the relevant changes, do you know

In order to try latest llvm, I will move to linux test run,
by using chadversary fork and report about GLES2 results
