Mold (linker) 1.0 released

In LTO, at some point during the compile, an internal representation of the program is written to the output object instead of machine code. During linking, the linker looks at all the objects and passes the compiler's internal representation back to the compiler which then generates the real object data that is returned to the linker to write into the output.

In the BFD linker this magic occurs with a plugin to the linker to find the LTO data, call the compiler and assemble the results.
