2010-08-14Always recurse into sub-cursors when annotating tokens, as this information ↵Ted Kremenek
is used for annotating macro arguments. This finishes up <rdar://problem/8044584>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111066 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-14As a heuristic, annotate tokens (via clang_annotateTokens) that are the ↵Ted Kremenek
arguments of a macro instantiation using the closest cursor with the same spelling location. Because macro arguments can get token pasted in any arbitrary order, we use the annotation map to paper over the token -> cursor annotations during our post-processing stage. This fixes most of <rdar://problem/8044584>, but still doesn't work for assert(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111062 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-13Implement caching of code-completion results for macro definitionsDouglas Gregor
when the CXTranslationUnit_CacheCompletionResults option is given to clang_parseTranslationUnit(). Essentially, we compute code-completion results for macro definitions after we have parsed the file, then store an ASTContext-agnostic version of those results (completion string, cursor kind, priority, and active contexts) in the ASTUnit. When performing code completion in that ASTUnit, we splice the macro definition results into the results provided by the actual code-completion (which has had macros turned off) before libclang gets those results. We use completion context information to only splice in those results that make sense for that context. With a completion involving all of the macros from Cocoa.h and a few other system libraries (totally ~8500 macro definitions) living in a precompiled header, we get about a 9% performance improvement from code completion, since we no longer have to deserialize all of the macro definitions from the precompiled header. Note that macro definitions are merely the canary; the cache is designed to also support other top-level declarations, which should be a bigger performance win. That optimization will be next. Note also that there is no mechanism for determining when to throw away the cache and recompute its contents. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111051 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-11Add a (currently unused) "options" parameter toDouglas Gregor
clang_reparseTranslationUnit(), along with a function to retrieve the default recommended reparsing options for a translation unit. Also, add the CXTranslationUnit_CacheCompletionResults flag, which is also currently unused. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110811 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-05Give clang_codeCompleteAt() an "options" parameter, and add a newDouglas Gregor
flags enumeration + default-generating function that allows code-completion to be customized via the libclang API. Plus, turn on spell-checking when performing code completion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110319 91177308-0d34-0410-b5e6-96231b3b80d8

file buffers until the code completion results are destroyed; diagnostics may end up referring into the source. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110216 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-04Add code-completion support directly to ASTUnit, which performs codeDouglas Gregor
completion within the translation unit using the same command-line arguments for parsing the translation unit. Eventually, we'll reuse the precompiled preamble to improve code-completion performance, and this also gives us a place to cache results. Expose this function via the new libclang function clang_codeCompleteAt(), which performs the code completion within a CXTranslationUnit. The completion occurs in-process (clang_codeCompletion() runs code completion out-of-process). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110210 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-03When using a precompiled preamble, keep track of the top-levelDouglas Gregor
declarations that we saw when creating the precompiled preamble, and provide those declarations in addition to the declarations parsed in the main source file when traversing top-level declarations. This makes the use of precompiled preambles a pure optimization, rather than changing the semantics of the parsed translation unit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110131 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-02Frontend: Change PluginASTAction::ParseArgs to take a CompilerInstance objectDaniel Dunbar
for use in reporting diagnostics. - We don't want to use the Action's own CompilerInstance, because that is only initialized during file processing and I like that invariant. Also, if ParseArgs returns false then abandon execution. Also, remove unused PluginASTAction::PrintHelp virtual method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110039 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-01Driver: Keep track of a separate "install dir", which is the path where clangDaniel Dunbar

CodeGenModule::MayDeferGeneration into a new function, DeclIsRequiredFunctionOrFileScopedVar. This function is part of the public CodeGen interface since it's essentially a CodeGen predicate that is also needed by the PCH mechanism to determine whether a decl needs to be deserialized during PCH loading for codegen purposes.

2010-07-22Improve performance during cursor traversal when a region of interestDouglas Gregor
is present. Rather than using clang_getCursorExtent(), which requires us to lex the token at the ending position to determine its length. Then, we'd be comparing [a, b) source ranges that cover the characters in the range rather than the normal behavior for Clang's source ranges, which covers the tokens in the range. However, relexing causes us to read the source file (which may come from a precompiled header), which is rather unfortunate and affects performance. In the new scheme, we only use Clang-style source ranges that cover the tokens in the range. At the entry points where this matters (clang_annotateTokens, clang_getCursor), we make sure to move source locations to the start of the token.
