...e linker ======================================= The linker loads all bitcode input files and performs symbol resolution. The IRSymtab already exposes the explicit section attributes for symbols; in our case, all symbols now carry this information. (2.1) In addition to communicating the exisiting SymbolResolution flags (VisibileToRegularObj etc.), the linker also matches the linker script, determines an output section for each symbol, and passes it to LTO as part of the SymbolResolution data structure. (2.2) The linker needs to determine an output section for *all* symbols, including those with interna...
