[llvm-dev] lld: ELF/COFF main() interface

[Yaron Keren via llvm-dev]

The context issue may be solved by making all functions and context data
members of a class. Sort of having the convenience of global variables
accessible from all linker functions but without the regular global
variable problems of initializing and re-entry. so the class is suitable
aspart of a library. Most clang and LLVM classes works this way, not
passing contexts around.
