RISC-V LLVM sync-up call 20th January 2022

For background on these calls, see here.

Reminder: the purpose is to coordinate between active contributors. If you have support questions etc then it’s best to post to LLVM’s Discourse or Discord.

We have a call every alternate Thursday at 4pm GMT, via this Google Meet link. If you have topics to discuss, please email me ahead of time and I can add them to the agenda.

We have a shared calendar that may help in keeping track, which is
accessible through:


  • Yet-to-be-ratified bitmanip extensions in LLVM.
  • LLVM 14.0 release schedule and RISC-V targets
    • Moving V extension from non-experimental?
    • Other in-flight ratified extension patches (crypto, supervisor spec updates, Zfinx, etc)
  • D111617 Lazily add RVV C intrinsics
  • Conventions for vendor extensions
  • D117731 Set CostPerUse to 1 iff RVC is enabled
  • Other heads-up
