Hi!
I’m trying to get more familiar with clang internals and I was trying to find the main function of the clang executable from the sources.
I was able to find clang_main() in driver.cpp. Is this the entry function or is there something else behind it (I mean properly named main() )?.
There were some older topics related to this, but I wasn’t sure if it has changed in 10+ years.
Thanks,
T
There is a properly named main. It is generated by the build system from llvm/cmake/modules/llvm-driver-template.cpp.in For clang, the file will be llvm/tools/clang/tools/driver/clang-driver.cpp in the build directory.
If ever in doubt, make it crash and see the stack trace 
Or checkout some issues with the crash label on the issue tracker.
The main function will get you into the driver internals. If you want to look at what the frontend does, maybe start with ParseAST.
Thanks, appreciate all the answers!
