[modules] Track how 'header' directives were written in module map files, rather than trying to extract this information from the FileEntry after the fact. This has a number of beneficial effects. For instance, diagnostic messages for failed module builds give a path relative to the "module root" rather than an absolute file path, and the contents of the module includes file is no longer dependent on what files the including TU happened to inspect prior to triggering the module build. llvm-svn: 223095

// This test explicitly cd's to the test/Modules directory so that we can test
// that filenames found via relative -I paths are printed correctly.

Generate a marker token when entering or leaving a submodule when building a module. Use the marker to diagnose cases where we try to transition between submodules when not at the top level (most likely because a closing brace was missing at the end of a header file, but is also possible if submodule headers attempt to do something fundamentally non-modular, like our .def files). llvm-svn: 195543

[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

// CHECK-A: While building module 'malformed_a'
[Modules] More descriptive diagnostics for misplaced import directive If an import directive was put into wrong context, the error message was obscure, complaining on misbalanced braces. To get more descriptive messages, annotation tokens related to modules are processed where they must not be seen. Differential Revision: http://reviews.llvm.org/D11844 llvm-svn: 248085

[modules] If we import a module, and we've seen a module map that describes the module, use the path from the module map file in preference to the path from the .pcm file when resolving relative paths in the .pcm file. This allows diagnostics (and .d output) to give relative paths if the module was found via a relative path. llvm-svn: 223577

Remove shell requirements from tests that use 'cd' Modules and Tooling tests in particular tend to want to change the cwd, so we were missing test coverage in this area on Windows. It should now be easier to write such portable tests. llvm-svn: 231029
