DESCRIPTION
The llvm-lib command is intended to be a lib.exe compatible
tool. See https://msdn.microsoft.com/en-us/library/7ykb2k5f for the
general description.
llvm-lib has the following extensions:
- Bitcode files in symbol tables.
llvm-lib includes symbols from both bitcode files and regular
object files in the symbol table.
- Creating thin archives.
The /llvmlibthin option causes llvm-lib to create thin archive
that contain only the symbol table and the header for the various
members. These files are much smaller, but are not compatible with
link.exe (lld can handle them).
