[roll] Roll fuchsia [starnix/usercopy] Introduce ASM `hermetic_copy` Currently, we build `hermetic_copy` from C++ source, but the hermetic copy error path assumes certain behaviour of the `hermetic_copy` implementation (see `hermetic_copy_error`. Compiling from C++ source is brittle because the generated assembly may change across toolchain updates. In fact, we have observed breakages several times. Now that the `hermetic_copy` is stable and we are not iterating on it anymore, provide an assembly variant of it that we can build from so that future toolchain updates do not break the build and, most importantly, we can explicitly provide the hermetic copy error path the guarantees/behaviours it expects. Note that we keep the `hermetic_copy` C++ source in tree as a reference. A later change will remove its `hermetic_code_blob` target from the regular build graph and likely move it to a test-only build target.

This repository contains Fuchsia's Global Integration manifest files.
All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.
Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.
First install Jiri.
Next run:
$ jiri init $ jiri import minimal https://fuchsia.googlesource.com/integration $ jiri update
Third party projects should have their own subdirectory in ./third_party.
