Appendix A: Getting Started: Installing LLVM and the Cpu0 example code¶
Cpu0 example code, lbdex, can be found near left bottom of this web site. Or here http://jonathan2251.github.io/lbd/lbdex.tar.gz.
For information in using cmake to build LLVM, please refer to the “Building
LLVM with CMake” 1 documentation for further information.
We install two llvm directories in this chapter. One is the directory ~/llvm/release/ which contains the clang and clang++ compiler we will use to translate the C/C++ input file into llvm IR. The other is the directory ~/llvm/test/ which contains our cpu0 backend program and clang.
Build steps¶
After setup brew install for iMac or install necessory packages. Build as https://github.com/Jonathan2251/lbd/blob/master/README.md.
Setting Up Your Mac¶
Brew install and setup first 2.
% /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
[#installbrew]_.
Then add brew command to your path as the bottom of installed message of bash above, like the following.
% echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/cschen/.zprofile
% eval "$(/opt/homebrew/bin/brew shellenv)"
Install Icarus Verilog tool on iMac¶
Install Icarus Verilog tool by command brew install icarus-verilog as follows,
% brew install icarus-verilog

Install other tools on iMac¶
Install Graphviz for display llvm IR nodes in debugging, 4.
% brew install graphviz
The Graphviz information for llvm is at section “SelectionDAG Instruction Selection Process” ” of “The LLVM Target-Independent Code Generator” here 5 and at section “Viewing graphs while debugging code” of “LLVM Programmer’s Manual” here 6.
Install binutils by command brew install binutils as follows,
// get brew by the following ruby command if you don't have installed brew
