[modules] When collecting declarations to complete a redeclaration chain for an entity, put the originally-canonical decl IDs in the right places in the redecl chain rather than reordering them all to the start. If we don't ensure that the redecl chain order is consistent with the topological module order, we can fail to make a declaration visible if later declarations are in more IDNSs than earlier ones (for instance, because the earlier decls are invisible friends). llvm-svn: 228978 2015-02-12 23:21:45 +00:00			`// RUN: rm -rf %t`
[modules] Simplify -cc1 interface for enabling implicit module maps. We used to have a flag to enable module maps, and two more flags to enable implicit module maps. This is all redundant; we don't need any flag for enabling module maps in the abstract, and we don't usually have -fno- flags for -cc1. We now have just a single flag, -fimplicit-module-maps, that enables implicitly searching the file system for module map files and loading them. The driver interface is unchanged for now. We should probably rename -fmodule-maps to -fimplicit-module-maps at some point. llvm-svn: 239789 2015-06-16 00:08:24 +00:00			`// RUN: %clang_cc1 -fmodules -fimplicit-module-maps -fmodules-cache-path=%t -I%S/Inputs/merge-decl-order -verify %s`
