jdc 21-may-2010 To learn LLVM I made a wrapper got LLVM's C API. This wrapper is available at: http://github.com/jdc8/llvmtcl
The wrapper uses LLVM's C API as found in LLVM's header file Core.h in include\llvm-c.
Requirements:
There is a Makefile to build the extension. Edit the Makefile to specify the paths to your Tcl and LLVM. Run make to build the extension. You'll also have to add LLVM's lib path to LD_LIBRARY_PATH.
