From a0c6a3571422826e856002714d9bb008584fe8b3 Mon Sep 17 00:00:00 2001 From: George Rimar Date: Wed, 14 Aug 2019 08:46:54 +0000 Subject: [llvm/Object] - Convert SectionRef::getName() to return Expected<> SectionRef::getName() returns std::error_code now. Returning Expected<> instead has multiple benefits. For example, it forces user to check the error returned. Also Expected<> may keep a valuable string error message, what is more useful than having a error code. (Object\invalid.test was updated to show the new messages printed.) This patch makes a change for all users to switch to Expected<> version. Note: in a few places the error returned was ignored before my changes. In such places I left them ignored. My intention was to convert the interface used, and not to improve and/or the existent users in this patch. (Though I think this is good idea for a follow-ups to revisit such places and either remove consumeError calls or comment each of them to clarify why it is OK to have them).
