Avoid a couple of assertions when preprocessing with modules 1. We were hitting the NextIsPrevious assertion because we were trying to merge decl chains that were independent of each other because we had no Sema object to allow them to find existing decls. This is fixed by delaying loading the "preloaded" decls until Sema is available. 2. We were trying to get identifier info from an annotation token, which asserts. The fix is to special-case the module annotations in the preprocessed output printer. Fixed in a single commit because when you hit 1 you almost invariably hit 2 as well. llvm-svn: 217550

[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

[modules] When using -E, we may try to merge decls despite having no Sema object. In such a case, use the TU's DC for merging global decls rather than giving up when we find there is no TU scope. Ultimately, we should probably avoid all loading of decls when preprocessing, but there are other reasonable use cases for loading an AST file with no Sema object for which this is the right thing. llvm-svn: 228234

Add pragma to perform module import and use it in -E output. Many of our supported configurations support modules but do not have any first-class syntax to perform a module import. This leaves us with a problem: there is no way to represent the expansion of a #include that imports a module in the -E output for such languages. (We don't want to just leave it as a #include because that requires the consumer of the preprocessed source to have the same file system layout and include paths as the creator.) This patch adds a new pragma: #pragma clang module import MODULE.NAME.HERE that imports a module, and changes -E and -frewrite-includes to use it when rewriting a #include that maps to a module import. We don't make any attempt to use a native language syntax import if one exists, to get more consistent output. (If in the future, @import and #include have different semantics in some way, the pragma will track the #include semantics.) llvm-svn: 301725
