[dev.link] cmd/link: directly use loader.ExtReloc in ELF relocation generation Convert the part that uses relocations to use loader.ExtReloc directly. It still uses sym.Symbols for now, but not sym.Relocs. This reduces some memory usage: linking cmd/compile with external linking, name old allocs/op new allocs/op delta Loadlibfull_GC 52.2MB ± 0% 13.9MB ± 0% -73.40% (p=0.008 n=5+5) name old live-B new live-B delta Loadlibfull_GC 75.5M ± 0% 61.9M ± 0% -18.02% (p=0.008 n=5+5) Change-Id: I317ecbf516063c42b255b2caba310ea6281342d7 Reviewed-on: https://go-review.googlesource.com/c/go/+/231319 Reviewed-by: Jeremy Faller <jeremy@golang.org> Reviewed-by: Than McIntosh <thanm@google.com>
