/tmp/lto-llvm-8f9b9a.o: reference to exp
How linker works in those cases?
In LTO build linker works in 2 phases:
1. Runs through all the inputs and identifies which of them should be processed by the plugin. But while doing that linker already starts filling it's symbol table.
Plugin at that poi...
