I'm in the Bay Area this week for the [7th RISC-V
Workshop](https://riscv.org/2017/10/7th-risc-v-workshop-agenda/), where I'll
be presenting about the RISC-V LLVM backend work that we have been
spearheading at lowRISC CIC. I hope to see some of you there.
## News and articles from around the web
The submission deadline for the LLVM toolchain devroom at FOSDEM 2018 [has
to Sunday 3rd December.
The next LLVM Social Berlin will take place [on Thursday 30th
It features a talk "Auto-tuning Compiler Transformations with Machine
Learning" by Dr. Biagio Cosenza.
A RISC-V Rust toolchain is [now
available](https://github.com/dvc94ch/riscv-rust-toolchain), courtesy of David
Craven. This builds on top of the ongoing [RISC-V LLVM backend
## On the mailing lists
* Jonas Paulsson is [looking for
on introducing new scheduling heuristics.
* Ben Hamilton proposes [having cfe-commits automatically CCed on Clang patch
This has now [been
for reviews submitted against the Clang repository.
* Hewlett Packard Enterprise have
that SPEC CPU 2017 scores for an AMD EPYC processor targeted by the LLVM-based
[AOCC](http://developer.amd.com/amd-aocc/) compiler are now available
## LLVM commits
* Initial support was added for Intel's Control-Flow Enforcement Technology.
* VPlan gained support for modeling masking.
* Further RISC-V codegen patches have landed.
* MC layer support was added for a number of Intel Icelake instructions.
[r318746](http://reviews.llvm.org/rL318746), and more.
## Clang commits
* The NetBSD Clang driver can now be used to enable ESan, KASan, MSan, and
* The `clang-tidy/rename_check.py` helper script gained support for moving
checks between modules, and this support was used to move a number of checks
from 'misc' to 'bugprone'. [r318905](http://reviews.llvm.org/rL318905).
## Other project commits
* The libcxxabi demangler now supports the `abi_tag` attribute.
* The LLDB code for parsing an ELF core file was refactored into smaller
## Review corner
The LLVM Weekly review corner serves to highlight patches that are stuck
waiting awaiting review, or work from first-time contributors. See
[here](http://llvmweekly.org/reviewcorner) for more information and how to
submit you work for inclusion. Of course the hope is that highlighting these
patches will enable LLVM Weekly readers will step up and help to get them
merged. I'll be reporting back each week on any activity generated on these
patches, as well as sharing a new batch. If you want your patch included you
must submit it via the linked form.
There were no new patch submissions this week.
