From 802bec896171997a7b73dde3857712e0eedeabc1 Mon Sep 17 00:00:00 2001 From: Vedant Kumar Date: Fri, 24 Jan 2020 18:07:34 -0800 Subject: [PATCH] Revert "Reland: [DWARF] Allow cross-CU references of subprogram definitions" ... as well as: Revert "[DWARF] Defer creating declaration DIEs until we prepare call site info" This reverts commit fa4701e1979553c2df61698ac1ac212627630442. This reverts commit 79daafc90308787b52a5d3a7586e82acd5e374b3.
