Improved jump-threading in LLVM for finite state automata
+ Evgeny We have a jump threading pass downstream for this that we would love to upstream. I believe Evgeny was working on exactly this, i.e. preparing it for upstreaming. ________________________________ From: llvm-dev <llvm-dev-bounces at lists.llvm.org> on behalf of Eli Friedman via llvm-dev <llvm-dev at lists.llvm.org> Sent: 23 September 2020 19:16 To: Phipps, Alan <a-phipps

Improved jump-threading in LLVM for finite state automata
Hi Sjoerd We (at Huawei) also have a pass for this. Originally we implemented this back in 2018 and meant to upstream it, but there were some issues with the implementation that required some changes in the code. We started revising it,a few weeks ago. I thought now that there are multiple options, maybe we can discuss our approaches, and see if there is a preference in the community for one

Improved jump-threading in LLVM for finite state automata
It is my understanding that the implementation for jump-threading in LLVM is not presently able to effectively optimize code containing a state-machine implemented using a loop + switch. This is the case, for example, with the Coremark benchmark function core_state_transition(). Bug 42313 was filed to address this in 2019: https://bugs.llvm.org/show_bug.cgi?id=42313 It appears that GCC

Modelling disease spread
I was at a lecture the other day and I saw a presentation of very neat (short) animation modeling epidemic disease spread over a map region. When I ask what software they used they mentioned SAS. Do you know if there are equivalent resources in R to model the spread of disease with animation output? My search in R-help and google didn't lead to any document (though I found a couple of

Agent-based social simulation and R
Do anyone know anything about the use of R for agent-based social simulation? It should be possible, and would be convenient for the simple reason that there are several nice packages containing useful stuff for SNA (Social Network Analysis). Information about packages, web sites, experienced persons in the field, etc. would be very welcome. Tom
