Check out Mesa's llvmpipe[1]:

> The Gallium LLVMpipe driver is a software rasterizer that uses LLVM to do runtime code generation. Shaders, point/line/triangle rasterization and vertex processing are implemented with LLVM IR which is translated to x86, x86-64, or ppc64le machine code. Also, the driver is multithreaded to take advantage of multiple CPU cores (up to 32 at this time). It’s the fastest software rasterizer for Mesa.

It is c++, then it is a definitive no-no. That's why I wrote my own in plain and simple C.
