Chris Lattner fb24a3a4ec push some source location information down through the compiler, 
into ContentCache::getBuffer.  This allows it to produce 
diagnostics on the broken #include line instead of without a 
location.

Dan Gohman 6e8427e066 Remove this hard-coded buffer size. In some basic experiments preprocessing 
large files, this doesn't seem significantly better than just letting
raw_ostream pick a buffer size.

This code predates raw-ostream's automatic buffer sizing; in fact, it
was introduced as part of the code which would eventually become
raw_ostream.

Douglas Gregor 4ad3da2843 Entering the main source file in the preprocessor can fail if the 
source file has been changed. Handle that failure more gracefully.

Daniel Dunbar 07d0785dbb PR5218: Replace IdentifierInfo::getName with StringRef version, now that clients 
are updated.

llvm-svn: 84447
 2009-10-18 21:17:35 +00:00
Daniel Dunbar 70e7eadd15 Move misc clients to IdentifierInfo StringRef API. 
- strcmp -> ==
 - OS.write(II->getName() ...) -> OS << II->getNameStr()
 - Avoid std::string concatenation
 - Use getNameStr().str() when an std::string is really needed.
