What are *.inc files in LLVM build

I am working with a debug build of llvm and writing a pass. It takes about 5-10 minutes to build every time I run 'make'. I see a lot of *.inc files getting build every time. What are those files and how can I make builds go faster?

Thanks

Solution

  • You are probably talking about files generated by TableGen utility. This process is slow for you because you've built it in Debug mode, probably. There is a CMake option called LLVM_OPTIMIZED_TABLEGEN to build TableGen in Release mode regardless the build type of all other projects.
