Hi all,

This and the previous week, I have been working on building AOSP's LLVM
toolchain for aarch64. tldr is that I have succeeded in doing so, but I
have yet to commit my progress at the (yet to be) SharkBait manifest[1].

Really there are just a couple of things to work on before we are ready
to build Android on arm64:

1. The build process is a bit immature. I will commit the polished
changes in a day or two at the LLVM source[2].

2. While trying to minimize dependencies that AOSP bundles for building
LLVM, I noticed that building LLVM requires using libraries from a
prebuilt gcc[3]. This is unwanted because we aim not to use any of the
prebuilt dependencies that AOSP ships. 
Therefore this week I am working upon building AOSP's gcc[4] for
aarch64.

Once the GCC dependency is sorted, I will start testing building Lineage
on aarch64. I have set a personal goal to atleast start these tests by
this week, since we do not have much time left.

Finally, I would like to thank my mentor, Heroxbd for providing the
arm64 server, due to which I could pick up the pace and build AOSP's
LLVM on aarch64.

Gunwant
