2*7c3d14c8STreehugger Robot * README.android describes in high-level the compiler-rt changes that we
3*7c3d14c8STreehugger Robot * cannot push upstream to the llvm.org repository:
4*7c3d14c8STreehugger Robot *  - Changes due to Android's build system.
5*7c3d14c8STreehugger Robot *  - Changes due to Android's toolchain.
6*7c3d14c8STreehugger Robot *  - Changes due to the limitations in Android-based consumer electronics.
7*7c3d14c8STreehugger Robot *
8*7c3d14c8STreehugger Robot * Some of them are to-dos. If and when they are done, there will no longer be
9*7c3d14c8STreehugger Robot * merge conflicts with upstream on those parts.
10*7c3d14c8STreehugger Robot *
11*7c3d14c8STreehugger Robot * The file contains useful hints when we try to resolve future 3-way merge
12*7c3d14c8STreehugger Robot * conflicts.

36*7c3d14c8STreehugger RobotTODO: This is still not building by default (no Android.mk files are present
37*7c3d14c8STreehugger Robotyet). Look at frameworks/compile/libbcc/runtime for potential starting points.
38*7c3d14c8STreehugger Robot
39*7c3d14c8STreehugger RobotTODO: Switch libbcc to use this version of compiler-rt instead of its own
40*7c3d14c8STreehugger Robottweaked version.
