cfbolz changed the topic of #pypy to: PyPy, the flexible snake (IRC logs: https://quodlibet.duckdns.org/irc/pypy/latest.log.html#irc-end ) | use cffi for calling C | if a pep adds a mere 25-30 [C-API] functions or so, it's a drop in the ocean (cough) - Armin

<antocuni> this twitter thread about apple's M1 might be interesting for pypy: https://twitter.com/ErrataRob/status/1331735383193903104
<antocuni> two highlight: it seem's that apple's ARM has a different behavior w.r.t memory ordering. I'm not sure whether this affects our JIT backend

<antocuni> 2. it seems they have added instructions to speedup javascript. I don't know what they are, but maybe we can use them for pypy as well

<antocuni> third highlight: "Another "magic" trick is how their "Swift" programming language uses "reference counting" instead of the "garbage collection" in Android. They did something in their CPU to double the speed of reference counting."
<antocuni> 😱

<mattip> I am not sure what is "off" with win64 on the py3.7 branch, but it cannot run any lib-python testing
<mattip> and crashes on own tests

<mattip> hmm. It seems the flag to increase the stack size is not working on win64

<mgorny> mattip: fyi, i've seen a segfault with pypy3.7 7.3.3, in pytest for Babel: https://dpaste.com/9V3GK94M2
<mgorny> but i can't reproduce it, seems pretty random

<mattip> mgorny: thanks. I wonder if it is a race condition caused by pytest assertion rewriting
<mattip> all: heptapod has updated and would like feedback if the slow push problem is better
<mattip> please comment there
