RISC-V Draft Compressed ISA version 1.9 released

The RISC-V Compressed Instruction Set Manual Version 1.9 Draft proposal has been released and is available at this link.  You can also download a PDF version at this link.

We welcome community feedback and comments on this draft. We believe this draft represents the close to final design for RV32C and RV64C (it seems premature to freeze R128C), though we are requesting one more round of comments, hence the 1.9 revision number. Please participate in the discussion on the public isa-dev mailing list (isa-dev@lists.riscv.org), to which you can subscribe at this link.

Thanks in advance for your help,
