- Based on the LLVM Kaleidoscope tutorial, but tried to use some good design principles I've learned from taking a compilers class.
- Mostly just a fun project done to learn more about LLVM.
mkdir build && cd build
cmake ..
makeThis project depends on LLVM libraries, so just having clang is not enough to build.
Execute ./Kale and then type in your program. Alternatively, pipe the text of
the program into stdin like the following:
./Kale < fib.klAn object file is output called output.o and the LLVM IR is dumped to stderr.
To try running a program, pipe stderr into another file and then call
clang on that. In the following example, I am using printd which is defined
in the print_dyn.cc file and created as the shared library "libprint". To
link with this library, do the following:
./Kale < fib.kl 2> fib.ir
clang -x ir fib.ir -L. -lprintThis assumes that you are executing the above commands in the build/ folder.
Finally, to correctly run the program with the dynamic library, the
LD_LIBRARY_PATH must be set to the directory where libprint.so is located
which is probably the current build directory.
Another way that a Kale program can be used is by linking with a C/C++
program by using the output.o file as an input to a clang build.
