DCPU-16 is the processor from Mojang's new game 0x10c. This project has a goal to make a full-featured LLVM backend for DCPU-16 and port Clang to support this architecture.
Currently llvm backend and Clang support are nearly fully implemented.
You can download a simple C SDK, which includes clang with the binutils port for dcpu16. It is Makefile based and contains a very simple C test program to demonstrate how you can develop your own program.
####Download#### You can find different precompiled packages for linux here.
There is also a very simple build script, which will assemble all needed parts for building the SDK yourself.
Please, let us know, if it does not work for you.
First, of all, you need to install prerequisites:
sudo apt-get install gcc g++ git subversion git-svn make\
perl gawk expect tcl texinfo bison autoconf automake cmake
Note, that when your python executable points to python3 (you can check that by running python --version) you have to replace "cmake .." with "cmake -DPYTHON_EXECUTABLE=/path/to/python2 .." in the following steps (path is /usr/bin/python2 in most cases)
Next, get the sources and build it:
git clone git://github.com/llvm-dcpu16/llvm-dcpu16.git # Checkout LLVM
cd llvm-dcpu16/tools
git clone git://github.com/llvm-dcpu16/clang.git # Checkout Clang
mkdir ../cbuild
cd ../cbuild
cmake ..
make -j4
Consider the following C file:
fib.c:
int fib(int n) {
int cur = 1;
int prev = 1;
for (int i = 0; i < n; i++) {
int next = cur+prev;
prev = cur;
cur = next;
}
return cur;
}
int main(void) {
return fib(5);
}Now, let's translate C to DCPU16 assembly:
bin/clang -ccc-host-triple dcpu16 -S fib.c -o fib.s
We generate DCPU16 v1.7 ASM with GAS compatible syntax. Most online assemblers won't work. Please use the binutils port for DCPU16 to assemble and link your program and then use an DCPU16 v1.7 compatible emulator to test your program.
Enjoy and, please, report bugs!
