* In C++, if the user redeclares a builtin function with a type that isDouglas Gregor2010-12-211-0/+4
| | | | | | | | | | | | | | | inconsistent with the type that the builtin *should* have, forget about the builtin altogether: we don't want subsequence analyses, CodeGen, etc., to think that we have a proper builtin function. C is protected from errors here because it allows one to use a library builtin without having a declaration, and detects inconsistent (re-)declarations of builtins during declaration merging. C++ was unprotected, and therefore would crash. Fixes PR8839. llvm-svn: 122351

* Fix diagnostic pragmas.Argyrios Kyrtzidis2010-12-153-22/+137
| | | | | | | | | | | | Diagnostic pragmas are broken because we don't keep track of the diagnostic state changes and we only check the current/latest state. Problems manifest if a diagnostic is emitted for a source line that has different diagnostic state than the current state; this can affect a lot of places, like C++ inline methods, template instantiations, the lexer, etc. Fix the issue by having the Diagnostic object keep track of the source location of the pragmas so that it is able to know what is the diagnostic state at any given source location. Fixes rdar://8365684. llvm-svn: 121873

* Fix 2 problems with Chris Lattner's FileManager redesign on Windows.Francois Pichet2010-11-241-1/+1

* The final result of all this refactoring: instead of doing stat immediatelyChris Lattner2010-11-232-6/+54
| | | | | | | | | | | | | followed by an open for every source file we open, probe the file system with 'open' and then do an fstat when it succeeds. open+fstat is faster than stat+open because the kernel only has to perform the string->inode mapping once. Presumably it gets faster the deeper in your filesystem a lookup happens. For -Eonly on cocoa.h, this reduces system time from 0.042s to 0.039s on my machine, a 7.7% speedup. llvm-svn: 120066

| | | | | | | | | | two copies, since they are fundamentally different operations and the StringRef one should go away (it shouldn't be part of FileManager at least). Remove some dead arguments. llvm-svn: 120013

* now the FileManager has a FileSystemOpts ivar, stop threadingChris Lattner2010-11-232-21/+11
| | | | | | | | | FileSystemOpts through a ton of apis, simplifying a lot of code. This also fixes a latent bug in ASTUnit where it would invoke methods on FileManager without creating one in some code paths in cindextext. llvm-svn: 120010
* give FileManager a 'FileSystemOptions' ivar, which will be usedChris Lattner2010-11-231-7/+7
| | | | | | | to simplify a bunch of code in it. It should ultimately get inlined into FileManager. llvm-svn: 120007
* Partially revert Doug's PCH validation patch (r98585).Chris Lattner2010-11-232-19/+7
| | | | | | | | | | | | | | | | | | | | | | This patch completely defeated the "passing in a prestat'd size to MemoryBuffer" optimization, leading to an extra fstat call for every buffer opened, in order to find out if the datestamp and size of the file on disk matches what is in the stat cache. I fully admit that I don't completely understand what is going on here: why punish code when a stat cache isn't in use? what is the point of a stat cache if you have to turn around and stat stuff to validate it? To resolve both these issues, just drop the modtime check and check the file size, which is the important thing anyway. This should also resolve PR6812, because presumably windows is stable when it comes to file sizes. If the modtime is actually important, we should get it and keep it on the first stat. This eliminates 833 fstat syscalls when processing Cocoa.h, speeding up system time on -Eonly Cocoa.h from 0.041 to 0.038s. llvm-svn: 120001

* Implement -working-directory.Argyrios Kyrtzidis2010-11-032-14/+53
| | | | | | | | | | | | | | | | | | | When -working-directory is passed in command line, file paths are resolved relative to the specified directory. This helps both when using libclang (where we can't require the user to actually change the working directory) and to help reproduce test cases when the reproduction work comes along. --FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains the working directory value if set). --FileSystemOptions are passed around to various interfaces that perform file operations. --Opening & reading the content of files should be done only through FileManager. This is useful in general since file operations will be abstracted in the future for the reproduction mechanism. FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same FileManager but with different FileSystemOptions.
