From f43e0ae7da27230ead43092268a315f87afbe3eb Mon Sep 17 00:00:00 2001 From: Peter Collingbourne Date: Mon, 10 Apr 2017 21:17:54 +0000 Subject: Bitcode: Merge the code for parsing global value module codes in the summary bitcode reader. NFCI. This code will need to be taught to handle string tables and it's better if there is only one copy of it.
