If a header is explicitly included in module A, and excluded from an umbrella directory in module B, don't include it in module B! llvm-svn: 205762 2014-04-08 21:13:04 +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 -x objective-c -fmodules -fimplicit-module-maps -fmodules-cache-path=%t -I %S/Inputs/exclude-header %s -verify`
