When loading a module fails because it is out of date, rebuild that module in place. <rdar://problem/10138913> llvm-svn: 167539

Avoid assumption that lit tests are writable (in a couple more places). NFC llvm-svn: 322065

[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

<rdar://problem/13363214> Eliminate race condition between module rebuild and the global module index. The global module index was querying the file manager for each of the module files it knows about at load time, to prune out any out-of-date information. The file manager would then cache the results of the stat() falls used to find that module file. Later, the same translation unit could end up trying to import one of the module files that had previously been ignored by the module cache, but after some other Clang instance rebuilt the module file to bring it up-to-date. The stale stat() results in the file manager would trigger a second rebuild of the already-up-to-date module, causing failures down the line. The global module index now lazily resolves its module file references to actual AST reader module files only after the module file has been loaded, eliminating the stat-caching race. Moreover, the AST reader can communicate to its caller that a module file is missing (rather than simply being out-of-date), allowing us to simplify the module-loading logic and allowing the compiler to recover if a dependent module file ends up getting deleted. llvm-svn: 177367
