Public review for Zicfilp and Zicfiss extensions

[Georgios Christou]

Dear all,

We are delighted to announce the public review for the Zicfilp

and Zicfiss standard extensions. The Zicfilp extension provides
landing pads for forward-edge control-flow integrity and the
Zicfiss extension provides shadow stacks for backward-edge
control-flow integrity. The 30-day review period begins today,

March 28, and concludes on April 27.

The specification is available for download as a PDF here:

https://github.com/riscv/riscv-cfi/releases/download/v1.0-rc1/riscv-cfi.pdf

To respond to the public review, please either email comments to the

public RISC-V ISA-Dev mailing list at isa...@groups.riscv.org or better add

issues to the GitHub repo at: https://github.com/riscv/riscv-cfi/issues

Should you encounter any issues accessing the document or the GitHub

links, please do not hesitate to contact us. We are eager to provide

assistance or furnish the document in an alternative format upon request.

We value all feedback and appreciate your contribution toward refining

this specification. Throughout the public review period, we will collect corrections,

comments, and suggestions for consideration by the Privileged and Unprivileged ISA

Committee. Minor corrections and/or non-controversial changes will be

incorporated into the specification directly. Any unresolved issues or

proposed modifications will be detailed in the public review summary report. 

Assuming no issues necessitate incompatible changes to the

specification under review, the Privileged ISA Committee will propose

that the updated specifications be ratified by both the RISC-V Technical

Steering Committee and the RISC-V Board of Directors.

We extend our gratitude to all contributors for their dedicated efforts.

Kind regards,

George, Ved
