Fix a bug reduced from a crash when trying to use modules with libc++. We check the linkage of functions and variables while merging declarations from modules, and we don't necessarily have enough of the rest of the AST loaded at that point to allow us to compute linkage, so serialize it instead. llvm-svn: 174943 2013-02-12 05:48:23 +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 -x objective-c++ -fmodules -fimplicit-module-maps -fmodules-cache-path=%t -I %S/Inputs %s -verify -std=c++11`
