I was using llvm-nm, but there are cases where the symbol is present in the .o file but it is marked as HIDDEN and llvm-readelf was what I was using to determine if the symbol was in fact marked as hidden. In these cases, the linker will not emit the symbol in the final .so file but it still needs the symbol as part of linking.

One way to workaround that would be to have a %llvm-readelf thing in lit and not run tests if not available (which also makes it questionable if it's not always running, but better than nothing?). Another option is to add a small clang tool that dumps what you need to check.


I will take a look at this. Thanks @bruno
