Hi, I'm an update about external/llvm status
android-n-preview-2 switched to llvm 3.8.0, the following branch has AMDGPU patches, even if named after marshamallow, changes were made on top llvm 3.8.0, after aosp switched with android-n-preview2: https://github.com/maurossi/llvm/tree/marshmallow-x86_llvm380_WIP2 NOTE: the latest branch is untested because I could not complete build with marshmallow and I did not dare to try building master, before Chih-Wei porting. The important thing is that between n-preview-1 and n-preview-2 (and AOSP master before N-preview2) moved to llvm 3.8.0, but I found in three distinct trials (master, n-preview-1, n-preview-2) that llvm3.8.0 would break marshmallow-x86 build, I have record of the build errors if needed. As a final note I would recommend not to use the same llvm version for different Android versions, we tried that in the past and there were several build breakages, so lollipop-x86 requires llvm 3.5.0, marshmallow-x86 requires 3.7.0 and android-n will require 3.8.0 Mauro 2016-04-30 22:31 GMT+02:00 Paulo Sergio <pstg...@gmail.com>: > > > I'm on AOSP master which probably means a different LLVM version. > > > First, I had to enable several LLVM libs to build for the target and > > > not just the host.
