* Remove 'const' from MemoryBuffers used through the SourceManagerDavid Blaikie2014-06-27
| | | | | | | | | | | | | | This removes a const_cast added in r211884 that occurred due to an inconsistency in how MemoryBuffers are handled between some parts of clang and LLVM. MemoryBuffers are immutable and the general convention in the LLVM project is to omit const from immutable types as it's simply redundant/verbose (see llvm::Type, for example). While this change doesn't remove "const" from /every/ MemoryBuffer, it at least makes this chain of ownership/usage consistent. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211915 91177308-0d34-0410-b5e6-96231b3b80d8

* Don't leak the CXStoredDiagnostics returned by clang_codeCompleteGetDiagnostic()Nico Weber2014-05-09
| | | | | | | | | | | | | | | | | | r144269 changed clang_disposeDiagnostic() to be a no-op, but didn't update code completion diagnostics. Let CXCodeCompleteResults store all diagnostics returned by clang_codeCompleteGetDiagnostic() and then free them up in clang_disposeCodeCompleteResults(). Code completion diagnostics referred to data stored in CXCodeCompleteResults before already, so it wasn't possible to refer to the results of clang_codeCompleteGetDiagnostic() after clang_disposeCodeCompleteResults() before this change already -- hence this should be a safe, backwards-compatible change. Leak found by LSan, fixes PR19690. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@208454 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove unnecessary inclusion of Sema.hDavid Blaikie2013-09-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let me tell you a tale... Within some twisted maze of debug info I've ended up implementing an insane man's Include What You Use device. When the debugger emits debug info it really shouldn't, I find out why & then realize the code could be improved too. In this instance CIndexDiagnostics.cpp had a lot more debug info with Clang than GCC. Upon inspection a major culprit was all the debug info describing clang::Sema. This was emitted because clang::Sema is befriended by DiagnosticEngine which was rightly required, but GCC doesn't emit debug info for friends so it never emitted anything for Clang. Clang does emit debug info for friends (will be fixed/changed to reduce debug info size). But why didn't Clang just emit a declaration of Sema if this entire TU didn't require a definition? 1) Diagnostic.h did the right thing, only using a declaration of Sema and not including Sema.h at all. 2) Some other dependency of CIndexDiagnostics.cpp didn't do the right thing. ASTUnit.h, only needing a declaration, still included Sema.h (hence this commit which removes that include and adds the necessary includes to the cpp files that were relying on this) 3) -flimit-debug-info didn't save us because of EnterExpressionEvaluationContext, defined inline in Sema.h which fires the "requiresCompleteType" check/flag (since it uses nested types from Sema and calls Sema member functions) and thus, if debug info is ever emitted for the type, the whole type is emitted and not just a declaration. Improving -flimit-debug-info to account for this would be... hard. Modifying the code so that's not 'required to be complete' might be possible, but probably only by moving EnterExpressionEvaluationContext either into Sema, or out of Sema.h. That might be a bit too much of a contortion to be bothered with. Also, this is only one of the cases where emitting debug info for friends caused us to emit a lot more debug info (this change reduces Clang's DWO size by 0.93%, dropping friends entirely reduces debug info by 3.2%) - I haven't hunted down the other cases, but I assume they might be similar (Sema or something like it). IWYU or a similar tool might help us reduce build times a bit, but analyzing debug info to find these differences isn't worthwhile. I'll take the 3.2% win, provide this small improvement to the code itself, and move on. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@190715 91177308-0d34-0410-b5e6-96231b3b80d8

* libclang: reduce CXString abuseDmitri Gribenko2013-02-07
| | | | | | | | | | ContainerUSR is not really a CXString, but it should own the underlying memory buffer. Thus, it is better to change the type to std::string.

A new code completion option that enables including brief comments into CodeCompletionString should be a, err, code completion option.

* [code-complete] Introduce CodeCompletionTUInfo which will be used for cachingArgyrios Kyrtzidis2012-04-10
| | | | | | | | | | | | | | | | | | | code-completion related strings specific to a translation unit (ASTContext and related data) CodeCompletionAllocator does such limited caching, by caching the name assigned to a DeclContext*, but that is not the appropriate place since that object has a lifetime that can extend beyond that of an ASTContext. Introduce CodeCompletionTUInfo which will be always tied to a translation unit to do this kind of caching and move the caching of CodeCompletionAllocator into this object, and propagate it to all the places where it will be needed. The plan is to extend the caching where appropriate, using CodeCompletionTUInfo, to avoid re-calculating code-completion strings.
