Meeting notes:
-- Deprecated SimpleV prefix format from 2019: <https://libre-soc.org/simple_v_extension/sv_prefix_proposal/>
-- RISC-V example extension: <https://github.com/riscv-software-src/riscv-isa-sim/blob/master/customext/cflush.cc>
-- The first step is to make modifications to `sv_analysis.py` to classify the RISC-V instructions.
- <https://git.libre-soc.org/?p=openpower-isa.git;a=blob;f=src/openpower/sv/sv_analysis.py;hb=HEAD>
-- Standard RISC-V opcode format: <https://github.com/riscv/riscv-opcodes>

-- [bug #980](https://bugs.libre-soc.org/show_bug.cgi?id=980)
- - A lot of work, need to focus on the basics
- - Issues with current Python pseudo-code compiler:
- - pseudocode is full of python-isms such as some variables are
- python ints and some are selectableint and some are strings etc.
- - plus, the parser currently has wrong operator precedence
- [bug #1082](https://bugs.libre-soc.org/show_bug.cgi?id=1082).
- - Suggested minimal goal for bug #980 is:
- - Use AST (operands, flow, etc. as we already do for generated
- Python func's) and a custom visitor function to convert to C code.
- - Generate C functions which can be compiled without errors.
- - Generated functions can be run from a main function to confirm results.
- - Jacob suggested using `maddedu` as a benchmark, since it has
- non-trivial pseudo-code.

+* [bug #672](https://bugs.libre-soc.org/show_bug.cgi?id=672)
+ added vggb, noted to shriya to research xbitmanip draft 0.94
+ to add to [[sv/cookbook/pospopcnt/]].
+ fixed a ton of elwidth-related bugs (elwidth overrides in
+ ISACaller were started as a "stub" for Indexed REMAP 8+
+ months ago)

+# --- TODO below here ---
# Dmitry
- Check with Dmitry on git commit descriptions (bug #1126).
Once comment made, add to [[HDL_workflow]] documentation.

-* [bug #672](https://bugs.libre-soc.org/show_bug.cgi?id=672)
- long story, pospopcount needs bmatflip (aka vgbbd in VSX)
- but also needed sv.bc fixing
- [bug #1215](https://bugs.libre-soc.org/show_bug.cgi?id=1215)
- which is related/similar to the DDFFirst issue on scalar source/dest
- [bug #1183](https://bugs.libre-soc.org/show_bug.cgi?id=1183)
- which jacob also noted for sv.cmpi/ff needed on bigmul.
-* Guide Dmitry on svanalysis.py.
-* Guide Shriya in Poly1305
- [bug #1157](https://bugs.libre-soc.org/show_bug.cgi?id=1157)
- and ED25519 [bug #1151](https://bugs.libre-soc.org/show_bug.cgi?id=1151)
- to assist Sadoon.

# Shriya
- Work together with Sadoon on Poly1305 and ED25519.
