+## How to upgrade llvm_git
+
+- Run `update-git.py`.
+  This will set the github revision and sha256 for `llvmPackages_git.llvm` to whatever the latest chromium build is using.
+  For a more recent, commit run `nix-prefetch-github` and change the rev and sha256 accordingly.
+
+- That was the easy part.
+  The hard part is updating the patch files.
+
+  The general process is:
+
+  1. Try to build `llvmPackages_git.llvm` and associated packages such as
+     `clang` and `compiler-rt`. You can use the `-L` and `--keep-failed` flags to make
+     debugging patch errors easy, e.g., `nix build .#llvmPackages_git.clang -L --keep-failed`
+
+  2. The build will error out with something similar to this:
+     ```sh
+     ...
+     clang-unstable> patching sources
+     clang-unstable> applying patch /nix/store/nndv6gq6w608n197fndvv5my4a5zg2qi-purity.patch
+     clang-unstable> patching file lib/Driver/ToolChains/Gnu.cpp
+     clang-unstable> Hunk #1 FAILED at 487.
+     clang-unstable> 1 out of 1 hunk FAILED -- saving rejects to file lib/Driver/ToolChains/Gnu.cpp.rej
+     note: keeping build directory '/tmp/nix-build-clang-unstable-2022-25-07.drv-17'
+     error: builder for '/nix/store/zwi123kpkyz52fy7p6v23azixd807r8c-clang-unstable-2022-25-07.drv' failed with exit code 1;
+            last 8 log lines:
+            > unpacking sources
+            > unpacking source archive /nix/store/mrxadx11wv1ckjr2208qgxp472pmmg6g-clang-src-unstable-2022-25-07

+            > patching file lib/Driver/ToolChains/Gnu.cpp
+            > Hunk #1 FAILED at 487.
+            > 1 out of 1 hunk FAILED -- saving rejects to file lib/Driver/ToolChains/Gnu.cpp.rej
+            For full logs, run 'nix log /nix/store/zwi123kpkyz52fy7p6v23azixd807r8c-clang-unstable-2022-25-07.drv'.
+     note: keeping build directory '/tmp/nix-build-compiler-rt-libc-unstable-2022-25-07.drv-20'
+     error: 1 dependencies of derivation '/nix/store/ndbbh3wrl0l39b22azf46f1n7zlqwmag-clang-wrapper-unstable-2022-25-07.drv' failed to build
+     ```
+
+     Notice the `Hunk #1 Failed at 487` line.
+     The lines above show us that the `purity.patch` failed on `lib/Driver/ToolChains/Gnu.cpp` when compiling `clang`.
+
+ 3. The task now is to cross reference the hunks in the purity patch with
+    `lib/Driver/ToolCahins/Gnu.cpp.orig` to see why the patch failed.
+    The `.orig` file will be in the build directory referenced in the line `note: keeping build directory ...`;
+    this message results from the `--keep-failed` flag.
+
+ 4. Now you should be able to open whichever patch failed, and the `foo.orig` file that it failed on.
+    Correct the patch by adapting it to the new code and be mindful of whitespace;
+    which can be an easily missed reason for failures.
+    For cases where the hunk is no longer needed you can simply remove it from the patch.
+
+ This is fine for small corrections, but when more serious changes are needed its better to use git.
+
+ 1. Clone the LLVM monorepo at https://github.com/llvm/llvm-project/
+
+ 2. Check out the revision we were using before.
+
+ 3. Use `patch -p1 < path/to-path` in the project subdirectories to apply the patches and commit.
+
+ 4. Use `git rebase HEAD^ --onto <dest>` to rebase the patches onto the new revision we are trying to build, and fix all conflicts.
+
+ 5. Use `git diff HEAD^:<project> HEAD:<project>` to get subdir diff to write back to Nixpkgs.
+
+## Information on our current patch sets
+
+### "GNU Install Dirs" patches
+
+Use CMake's [`GNUInstallDirs`](https://cmake.org/cmake/help/latest/module/GNUInstallDirs.html) to support multiple outputs.
+
+Previously, LLVM Just hard-coded `bin`, `include`, and `lib${LLVM_TARGET_PREFIX}`.
+We are making it use these variables.
+
+For the older LLVM versions, these patches live in https://github.com/Ericson2314/llvm-project branches `split-prefix`.
+Instead of applying the patches to the worktree per the above instructions, one can checkout those directly and rebase those instead.
+
+For newer LLVM versions, enough has has been upstreamed,
+(see https://reviews.llvm.org/differential/query/5UAfpj_9zHwY/ for my progress upstreaming),
+that I have just assembled new gnu-install-dirs patches from the remaining unmerged patches instead of rebasing from the prior LLVM's gnu install dirs patch.
