* Remove stray emacs mode markers in all these files that was causing emacs toNick Lewycky2010-12-3113-14/+14
| | | | | | | open them in fundamental-mode instead of c++-mode. Also twiddle whitespace for consistency in ToolChains.cpp. llvm-svn: 122646
* Add -fobjc-default-synthesized-properties flagTed Kremenek2010-12-232-0/+13
| | | | | | | | | | | | to allow us to explicitly control whether or not Objective-C properties are default synthesized. Currently this feature only works when using the -fobjc-non-fragile-abi2 flag (so there is no functionality change), but we can now turn off this feature without turning off all the features coupled with -fobjc-non-fragile-abi2. llvm-svn: 122519
* Fix PR8639 by making the "argument unused during compilation" less ↵Rafael Espindola2010-12-202-22/+16

| | | | | | | | | | | -Move the stuff of Diagnostic related to creating/querying diagnostic IDs into a new DiagnosticIDs class. -DiagnosticIDs can be shared among multiple Diagnostics for multiple translation units. -The rest of the state in Diagnostic object is considered related and tied to one translation unit. -Have Diagnostic point to the SourceManager that is related with.

* Use ld directly on linux. Changes from the previous try:Rafael Espindola2010-11-074-20/+373
| | | | | | | | | | | | | | | | | *) Try to detect as much as possible from the system itself, not the distro. This should make it easier to port to a new distro and more likely to work on a unknown one. *) The distro enum now doesn't include the arch. Just use the existing host detection support in LLVM. *) Correctly handle --sysroot. A small regression is that now clang will pass bitcode file to the linker. This is necessary for the gold plugin support to work. It might be better to detect this at configure/cmake time, but doing it in c++ first is a lot easier. llvm-svn: 118382
* Implement -working-directory.Argyrios Kyrtzidis2010-11-032-4/+15
| | | | | | | | | | | | | | | | | | | 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.

* Switch clang to run ld directly on linux. I tested this on all the linuxRafael Espindola2010-11-034-20/+489
| | | | | | | | | | | | | | | | | | | | | | distros listed by running gcc main.o -o main g++ main.o -o main gcc main.o -o main -static g++ main.o -o main -static gcc f.o -o f.so -shared g++ f.o -o f.so -shared and comparing the ld line with the one created by clang. I also added -m32/m64 in distros that support it. While I tested many distros, there will always be more. If you are hit by this it should be somewhat easy to add your distro. If you are in a hurry, do revert this, but please inform how to detect you distro and the ld command lines produced by the above gcc invocations. Most distros have some patches on gcc :-( llvm-svn: 118149
