2010-03-16Fix header-search problems with precompiled headers, where theDouglas Gregor
presence or absence of header map arguments when using the precompiled header would cause Clang to get confused about which headers had already been included/imported, along with their controlling macros. The fundamental problem is that the serialization of the header search information was relying on the UIDs of FileEntry objects at PCH generation time and PCH load time to be equivalent, which effectively means that we had to probe the same files in the same order. Differing header map arguments caused an extra FileEntry lookup, but it's easy to imagine other minor command-line arguments triggering this problem. Header-search information is now encoded along with the source-location entry for a file, so that we register information about a file's properties as a header at the same time we create the FileEntry for that file.

2010-03-16Introduce optional "Invalid" parameters to routines that invoke theDouglas Gregor
SourceManager's getBuffer() and, therefore, could fail, along with Preprocessor::getSpelling(). Use the Invalid parameters in the literal parsers (string, floating point, integral, character) to make them robust against errors that stem from, e.g., PCH files that are not consistent with the underlying file system. I still need to audit every use caller to all of these routines, to determine which ones need specific handling of error conditions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98608 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-15Introduce a new BufferResult class to act as the return type ofDouglas Gregor
SourceManager's getBuffer() (and similar) operations. This abstract can be used to force callers to cope with errors in getBuffer(), such as missing files and changed files. Fix a bunch of callers to use the new interface. Add some very basic checks for file consistency (file size, modification time) into ContentCache::getBuffer(), although these checks don't help much until we've updated the main callers (e.g., SourceManager::getSpelling()). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98585 91177308-0d34-0410-b5e6-96231b3b80d8
