The expanded checks in clang 10 made arm64 builds hit CFG crashes on nsXPTCStubBase vtables on startup.
It's not clear why this doesn't happen on x86 builds. Given our current level of support for arm64, I can't really justify investigating this, although I suspect that fixing the underlying issue would be pretty much bug 1483885.
As a get-unblocked stopgap, `-guard:cf,nochecks` in clang 10 gives the same behavior as `-guard:cf` in clang 9.

The "clang-9" variant of the patch is no longer present. For clang-7, the patch
file to use is now "find_symbolizer_linux.patch".

Configuration values defined above `mozconfig_options` in `init.configure` are those that can't be configured in `mozconfig`. As far as I can tell there is nothing wrong *in principle* with setting `PYTHON3` in `mozconfig`, so here we just bump `mozconfig_options` above `PYTHON3` configuration.
Side note, diagnosing this failure took a *long* time. The error message that this produced ("unknown option `PYTHON3`") is useless and the underlying algos being extremely mutable, I ended up having to spend a lot of time in the debugger and monitor all the underlying changes to a bunch of mutable data structures to determine where `PYTHON3` was getting lost. A better error message would be good here but I don't know how I would begin adding it.

iOS support for Gecko has not been tested in years and is most probably
out of date. The build system part of it, specifically the checks in
build/autoconf/ios.m4, are not trivial to port to python configure, and
they prevent other things from moving to python configure (because some
of them change value when MOZ_IOS is set).
The code is left alone, although it could probably be stripped off as
well, but I'll leave that as an exercise for someone else.

If we don't do this, configure will happily think the linker kind is
"unknown", which then causes problems downstream.

This patch is adding an option to push a perftest run in the CI.
It's based on :
- sparse profiles
- push_to_try
- options passed through try_task_config.json

ubsan's generated code trips an optimization corner case in clang 10. This is a short-term workaround. In the best case, llvm.org/pr45835 will land a fix soon, and we can merge that for our clang-10 update and not even land this patch. However, in case we're living in anything other than the best case world, I don't want to block on that happening.

Without this, taskgraph calculates the digest based on just the files in these
directories that are in the sparse profile (I suspect this is just the
moz.build files), and will rebuild it when those files change. This changes
ensures that all files in those directories are used to calculate the digest.
Additionally, this will cause the same digest to be generted by developers
locally, since the files *are* present in the non-sparse checkout that most
developers have.

As of bug 1621451 this argument was ignored, but it just silently runs your code with `python3` if you pass it anyway. Ensure this doesn't happen any more, and protect against any other unexpected arguments as well.

The license used to be LGPL so the code lived in other-licenses, but it was changed to BSD eleven years ago. Let's move it over to third_party/python/ply where it belongs.
./mach vendor python ply==3.10
`diff -r` between the original `ply` directory and the new one only comes up with the new file `third_party/python/ply/CHANGES` which isn't relevant to the functionality of the code, so this should be a no-op all told.
