2011-11-18Refine placement of LangOptions object in CompilerInvocation by adding a new ↵Ted Kremenek
baseclass CompilerInvocationBase with a custom copy constructor. This ensures that whenever the CompilerInvocation object's copy constructor is used we always clone the LangOptions object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144973 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-17Make 'LangOptions' in CompilerInvocation a heap-allocated, reference counted ↵Ted Kremenek
object. I discovered that llvm::RefCountedBase<T> has a bug where the reference count is copied in the copy constructor, which means that there were cases when the CompilerInvocation objects created by ASTUnit were actually leaked. When I fixed that bug locally, it showed that a whole bunch of code assumed that the LangOptions object that was part of CompilerInvocation was still alive. By making it heap-allocated and reference counted, we can keep it around after the CompilerInvocation object goes away. As part of this change, change CompilerInvocation:getLangOptions() to return a pointer, acting as another clue that this object may outlive the CompilerInvocation object. This commit doesn't fix the CompilerInvocation leak itself. That will come when I commit the fix to llvm::RefCountedBase<T> to mainline LLVM. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144930 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-07Rip out one of the features I added for the driver-include-management.Chandler Carruth
We don't actually need a separate flag for non-sysrooted paths as the driver has to manage the sysroot anyways. The driver is not infrequently adding paths to the header search based on their existence on the filesystem. For that, it has to add the sysroot anyways, we should pass it on down to CC1 already joined. More importantly, the driver cannot in all cases distinguish between sysrooted paths and paths that are relative to the Clang binary's installation directory. Essentially, we always need to ignore the system root for these internal header search options. It turns out in most of the places we were already providing the system root in the driver, and then another one in CC1 so this fixes several bugs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143917 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-05Fix a significant oversight in my move of MSVC includes to the driver:Chandler Carruth
actually manage the builtin header file includes as well as the system ones. This one is actually debatable whether it belongs in the driver or not, as the builtin includes are really an internal bit of implementation goop for Clang. However, they must be included at *exactly* the right point in the sequence of header files, which makes it essentially impossible to have this be managed by the Frontend and the rest by the Driver. I have terrible ideas that would "work", but I think they're worse than putting this in the driver and making the Frontend library even more ignorant of the environment and system on which it is being run. Also fix the fact that we weren't properly respecting the flags which suppress standard system include directories. Note that this still leaves all of the Clang tests which run CC1 directly and include builtin header files broken on Windows. I'm working on a followup patch to address that. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143801 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-05Add two flags to the CC1 layer that I was hoping to avoid. We need toChandler Carruth
encode the *exact* semantics which the header search paths internally built by the Frontend layer have had, which is both non-user-provided, and at times adding the implicit extern "C" bit to the directory entry. There are lots of CC1 options that are very close, but none do quite this, and they are all already overloaded for other purposes. In some senses this makes the command lines more clean as it clearly indicates which flags are exclusively used to implement internal detection of "standard" header search paths. Lots of the implementation of this is really crufty, due to the surrounding cruft. It doesn't seem worth investing lots of time cleaning this up as it isn't new, and hopefully *lots* of this code will melt away as header search inside of the frontend becomes increasingly trivial. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143798 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-29Start work on SerializedDiagnosticPrinter, a new DiagnosticConsumer that ↵Ted Kremenek
serializes out the diagnostics for a given translation unit to a bit code file. This is a WIP. The motivation for this new DiagnosticConsumer is to provide a way for tools invoking the compiler to get its diagnostics via a libclang interface, rather than textually parsing the compiler output. This gives us flexibility to change the compiler's textual output, but have a structured data format for clients to use to get the diagnostics via a stable API. I have no tests for this, but llvm-bcanalyzer so far shows that the emitted file is well-formed. More work to follow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143259 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-02Make -fobjc-nonfragile-abi the -cc1 default, since it's theJohn McCall
increasingly prevailing case to the point that new features like ARC don't even support the fragile ABI anymore. This required a little bit of reshuffling with exceptions because a check was assuming that ObjCNonFragileABI was only being set in ObjC mode, and that's actually a bit obnoxious to do. Most, though, it involved a perl script to translate a ton of test cases. Mostly no functionality change for driver users, although there are corner cases with disabling language-specific exceptions that we should handle more correctly now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140957 91177308-0d34-0410-b5e6-96231b3b80d8
