From 36528c2a9b3d37d6692de5738697598abfb5d9c8 Mon Sep 17 00:00:00 2001 From: Sean Fertile Date: Fri, 3 Nov 2017 21:45:55 +0000 Subject: [LTO][ThinLTO] Use the linker resolutions to mark global values as dso_local. Now that we have a way to mark GlobalValues as local we can use the symbol resolutions that the linker plugin provides as part of lto/thinlto link step to refine the compilers view on what symbols will end up being local.
