# LCPU
update readme to reflect move to cwgit

LCPU is an alternative CPU core addon for Garry's Mod and Wiremod.

It provides:

- A standard RISC-V architechure (rv32ima) CPU core, implemented in native code

- I know, but it wouldn't particularly be very good if I managed to implement it in Lua
(that and the more reasons to not use Lua for a part of this codebase, the better...)

- Interoperation with the Wiremod addon (and addons which implement Wiremod integration)

lcpu: officially support legacy 32bit branch 32-bit builds using the development headers work on the legacy 32-bit branch so I don't really see a reason to not support it.. sure, it sucks that I now won't be able to get rid of a pretty gnarly codepath, but /shrug

This addon works with both the non-beta branch and the x86-64 beta branches of GMod, however rigorous testing is usually only done with the x86-64 beta branch.

Note that the GitHub mirror is provided only for convinence, and is not used for active development.
See [this link](https://git.crustywindo.ws/modeco80/gmod-lcpu) for the actual development repository.

# Installation
lcpu: Misc cleanup LuaDevice now works fully, without any weird bugs. Yay! This took quite a bit of bugstomping to arrive to; some of which ended up discovering I'm not particularly proud of doing. Oops! The LuaCpu implementation no longer has a UART implementation in C++ (which actually leaked everytime a LuaCpu was garbage collected... Yeesh) - instead the Lua entity code actually implements the UART! Pretty cool to see the fruits of my labor actually working! The LuaHelpers macros are renamed slightly to make them less of a pain (and also because I think having `_IMPLEMENT` in a function implementation is a bit stupid.) I have updated the ideas document to better reflect my plans for the project system.

You will need Wiremod installed, either from the Workshop or cloned as a filesystem addon.
revert loggingsystem usage until I feel safe requiring x64 gmod

This repository is set up to be a Filesystem Addon; therefore, workflows which clone repositories from Git and put them in addons/ should be able to work with the LCPU addon just fine.

Windows building is currently untested; I see no reason why it wouldn't work.
add helper to build module and install it.

[CNLohr](https://github.com/CNLohr) - I may not like the mini-rv32ima code that much, but it did still help a lot (and my emulation core library is based off it, with tons of refactoring and a C++ rewrite to boot.), so thanks for creating the project.
