This repository is a utility for the development of my thesis. In other words, it is not the thesis project itself, but rather a utility that will evolve as my work requires. The goal of my thesis is to create an emulator for the Leon3 microprocessor, intended for satellite software development and simulators. To achieve this goal, it’s necessary to program each instruction supported by the Leon3 CPU. The decision has been made to automatically generate the template for each instruction using the utility libraries provided by LLVM, specifically table-gen.
This repository takes a part of the LLVM source code (files with the extension .td) as input and generates multiple .hpp format files for each of the supported instructions.
Once dependencies are installed and the project is compiled, it’s necessary to have the LLVM source code locally. To do this, you can execute:
git clone https://github.com/llvm/llvm-project.gitOnce cloned, you can use the program in the following way:
IG_PATH=/path/to/IntructionGenerator
LLVM_PATH=/path/to/cloned/llvm
$IG_PATH/IntructionGenerator \
-I$LLVM_PATH/llvm/include \
-I$LLVM_PATH/llvm/lib/Target/Sparc \
--emit-instructions $LLVM_PATH/llvm/lib/Target/Sparc/Sparc.tdFor example:
IG_PATH=~/Gits/leon3/intruction-generator/build/gcc-debug/src
LLVM_PATH=~/Gits/llvm-project
$IG_PATH/IntructionGenerator \
-I$LLVM_PATH/llvm/include \
-I$LLVM_PATH/llvm/lib/Target/Sparc \
--emit-instructions $LLVM_PATH/llvm/lib/Target/Sparc/Sparc.tdYou can also execute the command --help to get help.
