Andrew Waterman called Thursday and we discussed many issues including challenges with Issues in Github. We determined that both were unaware of some relevant aspects [neither of us intentionally blin

Hi, all I encountered a difficulty of applying "vrgather" instruction recently. The details are shown blow: The date from source should be duplicated as pair in a upsample application. Eg: src = [0, 1

I've just tagged the first release candidate for v1.0 of the vector spec in github. PDF attached below. I've included the TG agreed updates and handled almost all of the outstanding issues for v1.0. T

This is a good question. So if the RVM22 profile requires VLEN=32, ELEN=64, LMUL=8 then the vector registers will have the same amount of state as ARM MVE. Tariq

Hi, Krste: The RISC-V V TG have the plan to support a lowcost vector extension in RVMxx profile? Best Regards Shaofei 2021.6.3 -----邮件原件----- 发件人: krste@... [mailto:krste@...] 发送时间: 2021年6月3日 2:13 收件人

Hi all, I could not find any instruction that immediately computes this. Apologies if I missed the obvious here. Two options came to mind: vpopc.m and check whether the result is 0 (all zeros) or VLMA

Hi, We would like to announce that the RISC-V V-extension v0.10 has been implemented in LLVM and the work has been committed upstream. Barcelona Supercomputing Center (BSC), Codeplay Software, and SiF

Hi, I’m starting a project where we want to use vector intrinsics and generate both 64b and 32b code (for RV64 and RV32). It looks line the best way to do this right now is with GCC, where we were abl

Hi all, I’m still new to RISC-V and the Vector extensions, so forgive me if I’ve missed something, the following have been fixed or noted before. Also, am I sending this to the correct group for GCC R

Hi Vector Team, I’m new to RISC-V and the Vector extensions, so forgive me if I’ve missed something. I have searched the specs, emails and git hub issues, but not found anything on this: While writing

I haven’t seen any burning issues come by, and am still trying to clean up spec. So unless someone has agenda items, I’m canceling meeting tomorrow, Krste

I’m still working on spec cleanup and I don’ t have any major outstanding issues to discuss, so will cancel the TG meeting this week. Please bring up any burning issues on this mailing list, Krste

We'll meet again in usual slot. The main discussion topic will be #545. Please read the issue thread on github. Summary: The proposal is to move vector AMOs from their current encoding to leave space

There are a few issues to discuss, so we’ll meet in the regular time slot on the calendar, Krste

I'm cancelling meeting again, as I still have not been able to clean spec. I realize it will be more efficient for folks to wait for a clean version for a complete read through. Few issues are being r

I'm still working through spec cleanup. The list and github has been quiet, and I have no new issues to raise, so I suggest we cancel this meeting and push out for a week. Krste
