Ask HN: How to learn LLVM and why?

13 pointsSakiWatanabe9y ago3 comments

In the 500+ comments discussion yesterday[1] about the blog post "Being a Developer After 40"[2]. The author suggests ignore all the hype and learn all you can about LLVM. How do I get started and will learning LLVM benefit me? Can anyone share your experience?

I tried to write a C/C++ checker using LLVM/clang's libTooling, while solving a real problem we've encountered maintaining HPC code [1]. I found that I learned a lot about it that way. I wrote a brief article about the process [2]. Since then I've also participated in producing the official binaries for the linux distro I use at work. It's old enough that making it work requires lots of annoying bootstrapping. Getting used to the build process makes it a lot easier to start out new LLVM-based projects IMO.

I wanted to write something similar, but was turned off by the way you have to compile LLVM projects: your project mixed with LLVM sources. Also, its not that easy to get started.
