Do not print inferred submodules explicitly in __inferred_module.map Otherwise including a header in your source file that is not included by framework's umbrella header will silently add an empty submodule with that name. is automatically translated to @import Foo.NotInModule; which then would have succeeded because the inferred module map contained an empty submodule called NotInModule. llvm-svn: 207024 2014-04-24 05:10:46 +08:00			`// 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 08:08:24 +08:00			`// RUN: %clang_cc1 -fmodules -fimplicit-module-maps -fmodules-cache-path=%t -F %S/Inputs %s -verify`
