From 4f3f0acd6f7ba9c6688246262a6172ee0aa8488a Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 10 Mar 2020 00:00:17 +0000 Subject: Revert "Add new dwarf 5 enums, plus some dwarf4 enums." This reverts commit 0c0e24f709288a129d665ec27d6f089189318385. Reason for revert: This is causing breakage on CrOS due to unhandled enums and dwarf5 support is in limbo, so pull this back out for now.
