PR19215: When writing/reading a PCH that imported a module, store the location at which that PCH imported each visible submodule of the module. Such locations are needed when synthesizing macro directives resulting from the import. llvm-svn: 204417

[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

Allow multiple modules with the same name to coexist in the module cache To differentiate between two modules with the same name, we will consider the path the module map file that they are defined by* part of the ‘key’ for looking up the precompiled module (pcm file). Specifically, this patch renames the precompiled module (pcm) files from cache-path/<module hash>/Foo.pcm to cache-path/<module hash>/Foo-<hash of module map path>.pcm In addition, I’ve taught the ASTReader to re-resolve the names of imported modules during module loading so that if the header search context changes between when a module was originally built and when it is loaded we can rebuild it if necessary. For example, if module A imports module B first time: clang -I /path/to/A -I /path/to/B ... second time: clang -I /path/to/A -I /different/path/to/B ... will now rebuild A as expected. * in the case of inferred modules, we use the module map file that allowed the inference, not the __inferred_module.map file, since the inferred file path is the same for every inferred module. llvm-svn: 206201
