# RTSA-lab01-CacheAnalysis
|
||||
|
||||
In this lab session you will learn how to implement a LRU cache in abstract representation.
|
||||
The Goal is to implement an LRU must Join in include/AbstractState.h
|
||||
The Project can build, tested and Evaluated with the Helper Script.

Also I do not support the usage of Windows, Linux is free of charge so get a copy.
|
||||
I am more than happy helping you install Linux on your machine.
|
||||
|
||||
## Setup
|
||||
|
||||
We recommend using docker and VS Code for setup.
|
||||
If this is not your preferred Setup, take a look in the Docker file for the dependencies.
|
||||
I recommend using docker and VS Code for setup.
|
||||
Also check out the recommended extensions in the Docker section.
|
||||
If you prefer to work from Linux or Mac OS X, check the Dockerfile for dependencies.
|
||||
|
||||
Also we do not support the usage of Windows, Linux is free of charge so get a copy.
|
||||
Also make sure to have a LLVM13 install.
|
||||
|
||||
### Setting Docker up
|
||||
### Installing LLVM 13 on Mac OS X
|
||||
|
||||
On Darwin you can install LLVM 13 with [Homebrew](https://brew.sh/):
|
||||
|
||||
```bash
|
||||
brew install llvm@13
|
||||
```
|
||||
|
||||
If you already have an older version of LLVM installed, you can upgrade it to
|
||||
LLVM 13 like this:
|
||||
|
||||
```bash
|
||||
brew upgrade llvm
|
||||
```
|
||||
|
||||
Once the installation (or upgrade) is complete, all the required header files,
|
||||
libraries and tools will be located in `/usr/local/opt/llvm/`.
|
||||
|
||||
### Installing LLVM 13 on Ubuntu
|
||||
|
||||
On Ubuntu Bionic, you can [install modern
|
||||
LLVM](https://blog.kowalczyk.info/article/k/how-to-install-latest-clang-6.0-on-ubuntu-16.04-xenial-wsl.html)
|
||||
from the official [repository](http://apt.llvm.org/):
|
||||
|
||||
```bash
|
||||
wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add -
|
||||
sudo apt-add-repository "deb http://apt.llvm.org/bionic/ llvm-toolchain-bionic-13 main"
|
||||
sudo apt-get update
|
||||
sudo apt-get install -y llvm-13 llvm-13-dev llvm-13-tools clang-13
|
||||
```
|
||||
|
||||
This will install all the required header files, libraries and tools in
|
||||
`/usr/lib/llvm-13/`.
|
||||
|
||||
### Building LLVM 13 From Sources
|
||||
|
||||
Building from sources can be slow and tricky to debug. It is not necessary, but
|
||||
might be your preferred way of obtaining LLVM 13. The following steps will work
|
||||
on Linux and Mac OS X:
|
||||
|
||||
```bash
|
||||
git clone https://github.com/llvm/llvm-project.git
|
||||
cd llvm-project
|
||||
git checkout release/13.x
|
||||
mkdir build
|
||||
cd build
|
||||
cmake -DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD=host -DLLVM_ENABLE_PROJECTS=clang <llvm-project/root/dir>/llvm/
|
||||
cmake --build .
|
||||
```
|
||||
|
||||
For more details read the [official
|
||||
documentation](https://llvm.org/docs/CMake.html).

||||

### Run
|

Run the pass on a single test.

### Eval
|
||||
|
||||
Runs the Pass on a set of tests and also prints the expected results.
|
||||
This will be used to measure correctness of you implementation.
