   the future to be a bit shorter.  Rewrite this two places to use the
   proper way instead of a magic "40" (or at least assert that it was
   really 40).
+
+
+* use "CBNZ register, offset" (compare-and-branch-if-not-zero)
+  instead of a CMP+BNE pair.  Same with CBZ instead of CMP+BEQ
+
+
+* when we need to save things on the stack, we typically push two words
+  and pop them later.  It would be cheaper if we reserved two locations
+  in the stack from _call_header, then we could just write there.
+  *OR*
+  maybe it's enough if we use the form "str x0, [sp, !#offset]" which
+  combines in a single instruction the "str" with the change of sp

+
+      Don't assume gcc saves any register for us when generating
+      code for slp_switch().
+
+      The values 'save_state', 'restore_state' and 'extra' are first moved

+      Similarly, gcc expects 'result' to be in a register >= x19.
+      We don't want x18 to be used here, because of some special meaning
+      it might have.
+
+      This means that three of the values we happen to save and restore
+      will, in fact, contain the three arguments, and one of these values
+      will, in fact, not be restored at all but receive 'result'.
+
+      The following two points may no longer be true, because "x30" is
+      now present in the clobbered list, but the extra workarounds we
+      do might be safer just in case:
+
+          (1) Careful writing "blr %[...]": if gcc resolves it to x30---and it
+          can!---then you're in trouble, because "blr x30" does not jump
+          anywhere at all (it probably loads the current position into x30
+          before it jumps to x30...)
+
+          (2) Also, because "%[...]" can resolve to x30, we can't use that after
+          the first call.  Instead, we need to copy the values somewhere
+          safe, like x24 and x25.  We do that in such an order that it should

       Don't assume gcc saves any register for us when generating
       code for slp_switch().
 
       The values 'save_state', 'restore_state' and 'extra' are first moved
-      by gcc to some registers that are not marked as clobbered, so >= x19.
-      Similarly, gcc expects 'result' to be in a register >= x19.

+      some special meaning it might have.  We don't want x30 to be used
+      here, because it is clobbered by the first "blr".
 
       This means that three of the values we happen to save and restore
       will, in fact, contain the three arguments, and one of these values
       will, in fact, not be restored at all but receive 'result'.
-
-      The following two points may no longer be true, because "x30" is
-      now present in the clobbered list, but the extra workarounds we
-      do might be safer just in case:
-
-          (1) Careful writing "blr %[...]": if gcc resolves it to x30---and it
-          can!---then you're in trouble, because "blr x30" does not jump
-          anywhere at all (it probably loads the current position into x30
-          before it jumps to x30...)
-
-          (2) Also, because "%[...]" can resolve to x30, we can't use that after
-          the first call.  Instead, we need to copy the values somewhere
-          safe, like x24 and x25.  We do that in such an order that it should
-          work even if any of the "%[...]" expressions becomes x24 or x25 too.

+- Start the ARM64 backend (Armin, fijal) STARTED+DISCUSSIONS
+- Merging regalloc branch (CF, fijal, Armin)
+- Set up benchmarking machine (fijal, Matti)
+- Triage 3.6 failures and progress on them (&#321;ukasz, Ronan)       https://bitbucket.org/pypy/pypy/wiki/Status%20of%20PyPy3%20support%20for%203.6
+  - re and csv failures are done
+  - removed duplicate code
+  - next: fspath
+
+- zlib missing methods pypy2/3 (Julian, Anto) RZLIB DONE
+  - new failing tests: http://buildbot.pypy.org/summary?category=linux64&branch=%3Ctrunk%3E&recentrev=95849:c5c3ad13d149
+    - app-level test: when run on top of compiled PyPy, can't call function defined on interp-level
+    - lib-python test: .flush() sets .stream to nullptr, .copy() calls deflateCopy() with nullptr, it segfaults in RZlibError.fromstream()
+      - subtle difference: on CPython, z_stream is part of structure and can't become nullptr
+      - possible fixes: either handle .stream == nullptr in pypy module, or make RZlibError.fromstream() robust agains nullptr
+  - TESTS fixed? py3 problems
+- Fix RevDB (Manuel, Armin around) DONE
+
+- investigate struct.unpack weirdness (Antocuni, Julian)
+
+- Look into Windows failures on 3.5 (Manuel, Andy, Ronan around) - NANs are not consistent DONE
+
+- Windows installer (Andy, Matti) WORKS, needs adding to package.py
+
+
+
+## Tasks
+- Release 7.0 (Anto) reports version 7.1 :(
+- utf-8 progress/merging (Matti looking, Ronan will help)
+  NEEDS REVIEW. Benchmarks are [here](https://gist.github.com/mattip/05951f44e41224e36f00b62ebb4e2444) and [here](https://gist.github.com/mattip/d25536cd88ffe0361feca7760745a524). `logging.warn`, which is slow on py3.5 has gotten even worse SATURDAY
+
+- still one failing test in zlib branch untranslated (Ronan)
+
+- cpyext performance (Tim, Ronan around) Carl will ask Tim what is going on and file an issue
+
+- math-improvements branch (Alex to start) (REVIEW DONE, needs to be merged into default after the release, more bugs, benchmark on Py3?) (CF to merge into default/py3.5)
+
+- memoryview/ctypes bug https://bitbucket.org/pypy/pypy/issues/2930 (Matti, Armin around)
+
+- pypeg (lpeg reimplementation in RPython) (Stefan, Tim around, +?)
+
+- Tracker gardening
+
+- CFFI OS X bug (Maciej, Armin around)
+
+- finish fspath stuff (&#321;ukasz, CF around)
+
+- look at test_compile.py (&#321;ukasz, CF around)
+
+- asynio on Windows (Andy)
+
+- ARM32 build server (David, Matti, Maciek, Armin)
+
+- Answer Stefan Beyer email on pypy-dev
+
+
+## Tasks Saturday
+
+* let's look at spectral_norm after regalloc merge
+* utf-8 (Armin, CF, Matti, Maciek around)
+* progress on ARM64 (Maciek, David, Rodolph)
+
+
+## Discussions Done 
+
+- Think about Windows support - conclusion is to keep muddling along:
+
+  - There is money from SFC - who will do the work?
+  - Maybe the Microsoft people??????
+  - Andy has a first-attempt at a MSI packager 
+  - Try to have green buildbots and not much more?
+
+- Funding
+  - SFC - $69,000, $300 in OpenCollective
+  - Karen (SFC) Seem to be ready for us to part ways.
+  - We should spend the money. There are no marked funds.
+  - PLC needs to approve expenses.
+  - Python3.6/3.7/3.8: Ronan, Carl, Lucasz $30,000, incl. travel, salary
+  - Next sprint: summer?
+  - Cpyext: Antonio, Ronan $30,000, incl. travel, salary
+  - Buildbots: machines and website update $10,000
+  - pypy.org $2,000
+- Catching up with 3.6/3.7/3.8 - stop with py3.5
+
+- Intro talk (DONE)
+- Web Assembly (DONE)
+- Collaboration possibilities GraalPython around numpy stack TODAY
+- Scientific Stack
+- VMProf AFTER LUNCH
+- Unstuck Benchmarking - do it!! (decision made)
+- Packaging (wheels and conda) situation
+
+## Discussions
+- Infrastructure, testing: Travis, Azure Pipelines (1800 minutes per month) FRI MORNING
+- State and Future of PyPy 
+- apptest-file branch merge (Ronan)
+- focused sprint: when, where
+
+### Webassembly and PyPy
+
+### pyodide
+
+Python as an ecosystem is bad suited?
+
+PyPy should wait for GC support and DOM support.
+
+
+## Cython and GraalPython
+
+* Problem for GraalPython and PyPy (and numba) is that numpy is a black box
+* Other problem: handling expressions as a unit to not need to compute intermediate values
+* Numpy discussions around PyIR
+* Use (subset of) Cython or Cython-like to make [PyIR](https://docs.google.com/document/d/1jGksgI96LdYQODa9Fca7EttFEGQfNODphVmbCX0DD1k/edit#) real
+    * Cython is used by numeric people already, they are used to it
+    * as much Cython as possible
+    * compilable to something sensible
+* Cython is a tiny bit messy, it's a one-pass compiler
+* can we make Cython better designed?
+* potentially ask Oracle for funding
+
+## PyPy and the Numeric Stack
+
+* Important to support well, it's what many people use Python for
+* Problems:
+    * they don't use PyPy yet!
+    * numpy code tends to not be fast on PyPy
+    * the big libraries are hard to install
+    * we don't support wheels
+    * we don't support conda
+* Performance problems:
+    * cpyext speedups
+    * long term plans around cython or similar
+* maybe building wheels is going to be easier with manylinux2010?
+* let's try to build pypy on the right manylinux2010
+* conda doesn't care about us
+* they want us to do work?
+* but we would need changes in conda and deep understanding on their side
+    * Open issue with design proposal: https://github.com/conda/conda/issues/6950
+* contrete tasks:
+    * try to build manylinux2010 pypy
+    * talk to conda people?
+
+
+## ``VMProf``
+
+* Problems with vmprof:
+    * frontend: graphs are hard to understand
+        * kills buildbot host
+        * we need to maintain it
+        * huge RAM usage
+    * backend:
+        * rpython functions not profiled correctly
+    * what's the scope of vmprof?
+    * no "customers"/motivation
+
+* Scope:
+    * ???
+* Frontend:
+    * Can we make our life easier by using somebody else's frontend?
+        * Chrome devtools
+        * PyCharm
+        * https://github.com/KDAB/hotspot
+
+* Backend:
+    * profiling in production
+        * make it cheap enough
+        * make it easy to turn on and off
+        * make it possible to deal with data in-process
+    * the vmprof pure python modules is badly implemented
+    * boring parts: rpython functions
+
+ * steps:
+     * improve the vmprof module to not suck
+     * make ``_vmprof`` should always provide reliable data
+     * make local deployment very simple
+
+* we should be able to connect source code and traces
+* unique identifiers for loops from the JIT
+  * what happens if the loop is formed before `_vmprof` is on
+      * just have it always on ;-)
+  * how to connect pieces of traces to source code? Offets, pieces of loops, code in memory do not always map back to source file
+  * exposes bugs that probably already exist but we don't care
+    * blackhole, generated code, tracing, ...
+  * debug_merge_point is not necesssarily always correct
+* when you have correct input you see correct output, but when you do not have correct input do not show garbage
+
+##### Summary
+
+* Can we make an improved JitViewer with statistical profiling info? Will it be helpful?
+  * what about tracing? blackhole? Function repitition? Fix it in `_vmprof` !
+
+* Possible architecture:
+  * _vmprof feeds data to a socket
+  * separate program reads the data and distills it into a known format
+  * that is presented in a known frontend
+
+* Better packaging and API 
+  * callback hook function what to do with the info: socket, file, 
+  * on/off per block, 
+  * on/off generally which would not necessarily add overhead but would allow later on/off on a lower level.
+  * allow self-reporting of global/per-thread/per-green thread state of the app
+
+## Discussion: State and Future of PyPy
+* Let's try to have team-internal "office hours" Monday 10.00-13.00 to deal with the reduced availability of people
+* How can we constructively interact with CPython-dev?
+    * maybe a PEP?
+    * what are concrete things that would be good to have in there?
+    * something about C-API?
+    * having cpython implementation details marked as such in the regression tests
+    * have people from other implementations be invited to lang summit
+* when PyPy 3.6 is out, we should get other projects to run their tests on PyPy
+* How do we grow the community?
+    * Advertise sprints more widely
+    * steal some cpython devs?
+    * move away from bitbucket.org?
+    * beginner mentoring program
+    * blog posts, videos
+        * "PyPy internals for CPython devs"
+    * twitch streams?
+    * docs are a mess
+    * success stories on the web page
+* What can we stop doing (brainstorming)
+    * dropping platforms?
+    * maintain own fork of pytest
+    * using less custom infrastructure
+
+## disjointed benchmarking notes
+* ask whether we can use speed.python.org
+* run benchmarks weekly

Log:	fix AppTestSocket.().test_invalid_fd

	Rename the kwarg from fdobj to fileno. fdobj comes from the C
	implementation of _socket in cpython but the test specifies it by
	keyword so it needs to be changed accordingly.

+* cond_call and following guard_exception
+
+
+* We can try to make generate_quick_failure() emit two instructions less:
+  the two store_reg() [one in generate_quick_failure and the other in
+  push_gcmap].  Instead we'd load the values in ip2 and ip3, and the
+  store_regs would occur inside self.failure_recovery_code
+  (which 'target' points to).
+
+
+* use STP instead of STR in all long sequences of STR.  Same with LDR
+
+* use "STR xzr, [..]" instead of "gen_load_int(ip, 0); STR ip, [..]".
+  Search around for gen_load_int(...0): it occurs at least in pop_gcmap()
+  _build_failure_recovery(), build_frame_realloc_slowpath(), etc.
+
+
+* malloc_cond() and malloc_cond_varsize_frame() hard-code forward jump
+  distances by guessing the number of instructions that follows.  Bad
+  idea because some of these instructions could easily be optimized in
+  the future to be a bit shorter.  Rewrite this two places to use the
+  proper way instead of a magic "40" (or at least assert that it was
+  really 40).
+
+
+* use "CBNZ register, offset" (compare-and-branch-if-not-zero)
+  instead of a CMP+BNE pair.  Same with CBZ instead of CMP+BEQ
+
+
+* when we need to save things on the stack, we typically push two words
+  and pop them later.  It would be cheaper if we reserved two locations
+  in the stack from _call_header, then we could just write there.
+  *OR*
+  maybe it's enough if we use the form "str x0, [sp, !#offset]" which
+  combines in a single instruction the "str" with the change of sp

Log:	Change the API of rffi.get_nonmovingbuffer(), now renamed to
	rffi.get_nonmovingbuffer_ll(), because it is not safe: it needs to
	return the real llstr object on which it operated, and this is the
	object that needs to be passed to free_nonmovingbuffer_ll().

	Otherwise, it's possible to come up with rpython code that would,
	say, convert a char to a string once for get() and once for free(),
	which defeats pinning.

+Hello everyone
+
+We are pleased to announce that we have successfully ported PyPy
+to Aarch64 (also known as a 64bit ARM) platform, thanks to funding
+provided by ARM Holdings Ltd. and Crossbar.io.
+
+We are presenting here the benchmark run done on a Graviton A1 machine
+from AWS. There is a very serious word of warning: Graviton A1 are
+virtual machines and as such, are not suitable for benchmarking. If someone
+has access to a beefy enough (16G) ARM64 server and is willing to give
+us access to it, we are happy to redo the benchmarks on a real machine.
+My main concern here is that while a vCPU is 1-1 with a real CPU, it's not
+clear to me how caches are shared and how they cross CPU boundaries.
+
+We are not interested in comparing machines, so what we are showing is
+a relative speedup to CPython (2.7.15), compared to PyPy (hg id 2417f925ce94).
+
+In the last column is a comparison - how much do we speedup on arm64, vs
+how much do we speed up on x86_64. One important thing to note is that
+by no means this is a representative enough benchmark set that we can average
+anything. Read numbers per-benchmark.

+Note that we see a wide variance. There are generally three groups of
+benchmarks - those that run at more or less the same speed, those that
+run at 2x the speedup and those that run at 0.5x the speedup of x86_64.
+
+This can be related to a variety of issues, mostly related to differences
+in architecture. What *is* however interesting is that compared to older
+ARM boards, the branch predictor got a lot better, which means the speedups
+will be smaller, since "sophisticated" branchy code, like source code of
+CPython just runs a lot faster.
+
+One takeaway here is that there is a lot of improvement to be done in PyPy.
+This is true for both of the above platforms, but probably more so for Aarch64
+which comes with really a lot of registers. PyPy backend has been written with
+x86 (the 32bit variant) in mind, which is very register poor. We think we can
+improve somewhat in the area of emitting more modern code and it will probably
+make somewhat more difference on Aarch64 than on x86_64, where running old
+crappy code efficiently has been a massive focus.

+In the majority of benchmarks, the speedups achieved on AArch64 match those
+achieved on the x86_64 laptop. Over CPython, PyPy on AArch64 achieves speedups
+between 0.6x to 44.9x. These speedups are comparable to x86_64, where they are
+between 0.6x and 58.9x.
+
+The next graph compares between the speedups achieved on AArch64 to the speedups
+achieved on x86_64, i.e., how much the speedup is on AArch64 vs. the same
+benchmark on x86_64. Note that by no means is this benchmark suite
+representative enough to average the results. Read the numbers individually per
+benchmark.
+
+.. image:: 2019-07-arm64-relative.png
 
 Note also that we see a wide variance. There are generally three groups of
 benchmarks - those that run at more or less the same speed, those that
-run at 2x the speedup and those that run at 0.5x the speedup of x86_64.
+run at 2x the speed and those that run at 0.5x the speed of x86_64.
 
-The variance and disparity are likely related to a variety of issues,
-mostly due to differences in architecture. What *is* however
-interesting is that compared to older ARM boards, the branch predictor
-has gotten a lot better, which means the speedups will be smaller:
-"sophisticated" branchy code like CPython itself just runs a lot faster.
+The variance and disparity are likely related to a variety of issues, mostly due

+by PyPy over CPython are smaller: "sophisticated" branchy code, like CPython
+itself, simply runs a lot faster.
 
 One takeaway here is that there is a lot of improvement left to be done
 in PyPy. This is true for both of the above platforms, but probably more
 so for AArch64, which comes with a large number of registers. The PyPy
 backend was written with x86 (the 32-bit variant) in mind, which is very
 register poor. We think we can improve somewhat in the area of emitting
-more modern machine code, which should be more impactful for AArch64
-than x86_64. There are also still a few missing features in the AArch64
-backend, which are implemented as calls instead of inlined instructions,
-which we hope to improve.

+# PyPy's SSL module
+
+All of the CFFI code is copied from cryptography, wich patches contributed
+back to cryptography. PyPy vendors it's own copy of the cffi backend thus
+it renames the compiled shared object to _pypy_openssl.so (which means
+that cryptography can ship their own cffi backend)
+
+NOTE: currently, we have the following changes:
+
+* ``_cffi_src/openssl/callbacks.py`` to not rely on the CPython C API
+  (this change is now backported)
+
+* ``_cffi_src/utils.py`` for issue #2575 (29c9a89359e4)
+
+* ``_cffi_src/openssl/x509_vfy.py`` for issue #2605 (ca4d0c90f5a1)
+
+* ``_cffi_src/openssl/pypy_win32_extra.py`` for Win32-only functionality like ssl.enum_certificates()
+
+
+# Tests?
+
+Currently this module is tested using CPython's standard library test suite.
+
+# Install it into PyPy's source tree
+
+Copy over all the sources into the folder `lib_pypy/_cffi_ssl/*`. Updating the cffi backend can be simply done by the following command::
+
+    $ cp -r <cloned cryptography folder>/src/_cffi_src/* .
+
+NOTE: you need to keep our version of ``_cffi_src/openssl/callbacks.py``
+for now!
+
+# Crpytography version
+
+Copied over release version `1.7.2`

 We are pleased to announce the availability of the new PyPy for AArch64. This

+`apptest_` prefix and look like this::
 
-    def app_test_something():
+    def test_this():
         # application level test code
 
+These application level test functions will run on top
+of PyPy, i.e. they have no access to interpreter details.
+
+By default, they run on top of an untranslated PyPy which runs on top of the
+host interpreter. When passing the `-D` option, they run directly on top of the
+host interpreter, which is usually a translated pypy executable in this case::
+
+    pypy3 -m pytest -D pypy/
+
+Note that in interpreted mode, only a small subset of pytest's functionality is
+available.
+
+Mixed-level tests (deprecated)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Mixed-level tests are similar to application-level tests, the difference being
+that they're just snippets of app-level code embedded in an interp-level test
+file, like this::
+
     class AppTestSomething(object):
         def test_this(self):
             # application level test code
 
-These application level test functions will run on top
-of PyPy, i.e. they have no access to interpreter details.
 You cannot use imported modules from global level because
 they are imported at interpreter-level while you test code
 runs at application level. If you need to use modules
