Hi all, |
| 2 |
|

This and the previous week, I have been working on building AOSP's LLVM |
| 4 |
toolchain for aarch64. tldr is that I have succeeded in doing so, but I |
| 5 |
have yet to commit my progress at the (yet to be) SharkBait manifest[1]. |
| 6 |
|
| 7 |
Really there are just a couple of things to work on before we are ready |
| 8 |
to build Android on arm64: |
| 9 |
|
| 10 |
1. The build process is a bit immature. I will commit the polished |
| 11 |
changes in a day or two at the LLVM source[2]. |
| 12 |
|
| 13 |
2. While trying to minimize dependencies that AOSP bundles for building |
| 14 |
LLVM, I noticed that building LLVM requires using libraries from a |
| 15 |
prebuilt gcc[3]. This is unwanted because we aim not to use any of the |
| 16 |
prebuilt dependencies that AOSP ships. |
| 17 |
Therefore this week I am working upon building AOSP's gcc[4] for |
| 18 |
aarch64. |
| 19 |
|
| 20 |
Once the GCC dependency is sorted, I will start testing building Lineage |
| 21 |
on aarch64. I have set a personal goal to atleast start these tests by |
| 22 |
this week, since we do not have much time left. |
| 23 |
|
| 24 |
Finally, I would like to thank my mentor, Heroxbd for providing the |
| 25 |
arm64 server, due to which I could pick up the pace and build AOSP's |
| 26 |
LLVM on aarch64. |
