im currently trying to generate LLVM IR with ANTLR3. But the problem ist, that i need the C target (C++ would be better but is not working yet, or is it?) but from C i can t call the LLVM C++ API for Building the IR.
The Tutorial from Terence Parr uses Java and the StringTemplate lib. But as i know the StringTemplate lib ist not available for C.
Does anyone have some good ideas how this can be done? :)
Thx
there is a very good entry in the LLVM faq, discussing what you want to do: http://llvm.org/docs/FAQ.html#langirgen It points to llvm-c, which is a C binding to llvm, allowing to generate IR directly from C, and is integrated to llvm since at lease llvm-2.6
The approach Terence takes in its example with antlr-java and stringtemplates is to generate llvm assembly as text (and generating text is really what stringtemplates is about).

I have been able to build LLVM 2.6 (the llvm-2.6.tar.gz package) using MinGW GCC 3.4.5. I haven t tested properly, but it seems to work. The trouble is, I have libraries of my own which don t build ...
There are many static and dynamic instrumentation tools. Soot is a static instrumentation tool for Java bytecode. Pin and Valgrind are dynamic instrumentation tools for binaries. What are pros and ...
I m bootstrapping a programming language compiler on top of LLVM. Currently I m mostly done writing a compiler for a subset of C which is self-compiling. When I m finished with that, I ll bootstrap ...

I have generated a bc file with the online compiler on llvm.org, and I would like to know if it is possible to load this bc file from a c or c++ program, execute the IR in the bc file with the llvm ...
From llvm.org I ve downloaded llvm-2.6-x86-mingw32.tar.bz2 into c:llvm and llvm-gcc-4.2-2.6-x86-mingw32-tar.bz2 into c:llvm-gcc as well as setup a desktop shortcut the following batch file in c:...
Let s assume for the moment that C++ is not a functional programming language. If you want to write a compiler using LLVM for the back-end, and you want to use a functional programming language and ...
