[otbn] Handle signed immediate operands properly in tooling Now, the ISA data in insns.yml specifies whether an immediate operand is signed or not (usually not, except for RV32I instructions). The .insn-matching logic in otbn-as fixes things up accordingly and we actually lose one instruction: LOOP no longer fits in a RISC-V standard encoding. Finally, objdump should now disassemble signed immediates correctly. Signed-off-by: Rupert Swarbrick <rswarbrick@lowrisc.org>
OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
