Implement support for module requirements, which indicate the language features needed for a particular module to be available. This allows mixed-language modules, where certain headers only work under some language variants (e.g., in C++, std.tuple might only be available in C++11 mode). llvm-svn: 147387

// RUN: rm -rf %t
[Modules] Change private modules rules and warnings We used to advertise private modules to be declared as submodules (Foo.Private). This has proven to not scale well since private headers might carry several dependencies, introducing unwanted content into the main module and often causing dep cycles. Change the canonical way to name it to Foo_Private, forcing private modules as top level ones, and provide warnings under -Wprivate-module to suggest fixes for other private naming. Update documentation to reflect that. rdar://problem/31173501 llvm-svn: 321337

Factor out and unify emission of "module is unavailable" diagnostics. Inspired by post-commit review of r304190. llvm-svn: 304728

Allow a new syntax in a module requires-declaration: requires ! feature The purpose of this is to allow (for instance) the module map for /usr/include to exclude <tgmath.h> and <complex.h> when building in C++ (these headers are instead provided by the C++ standard library in this case, and the glibc C <tgmath.h> header would otherwise try to include <complex.h>, resulting in a module cycle). llvm-svn: 193549

Add cc1 option '-fmodule-feature' to add custom values for 'requires' decls This allows clang-based tools to specify custom features that can be tested by the 'requires' declaration in a module map file. llvm-svn: 227868

[Modules] Allow missing header before a missing requirement And make the module unavailable without breaking any parent modules. If there's a missing requirement after we've already seen a missing header, still update the IsMissingRequiement bit correctly. Also, diagnose missing requirements before missing headers, since the existence of the header is moot if there are missing requirements. llvm-svn: 242055
