2010-10-18Add declarations nested in a linkage specification to the output ofDouglas Gregor
-ast-print-xml, from Martin Vejnar! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116702 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-14Wire up the -fstrict-aliasing and -fno-strict-aliasing optionsDan Gohman
to CodeGenOption flags. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116530 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-14Introduce command line option -error-on-deserialized-decl that is ↵Argyrios Kyrtzidis
accompanied by a name and emits an error if a declaration with this name is deserialized from PCH. This is for testing, to make sure that we don't deserialize stuff needlessly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116505 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-14Introduce command line option -dump-deserialized-decls which is used to ↵Argyrios Kyrtzidis
print the PCH decls that got deserialized, for testing purposes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116503 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-12When we load an ASTUnit from command-line arguments, hold on to theDouglas Gregor
diagnostics produced by the driver itself. Previously, we were allowing these to either be dropped or to slip through to stderr. Fixes <rdar://problem/7595339>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116285 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-11Eliminate the (de-)serialization of code completion results, now thatDouglas Gregor
libclang does not support out-of-process code completion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116253 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-11Eliminate -fdiagnostics-binary and all of the infrastructure forDouglas Gregor
emitting diagnostics in a binary form to be consumed by libclang, since libclang no longer does any of its work out-of-process, making this code dead. Besides, this stuff never worked at 100% anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116250 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-11Declare argv parameters as const char* const* instead of to char** to ↵Axel Naumann
clarify that they are not modified, and to allow for string literals as arguments. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116200 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-11Tighten up constness of argv parameters to allow for string literals as ↵Axel Naumann
argumants and to reflect actual (non-modifying) use. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116199 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-05Give every file that ASTReader loads a type: module, PCH, precompiled ↵Sebastian Redl
preamble or main file. Base Decls' PCHLevel on this to make it more sane. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115626 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-30Introduce -flimit-debug-info.Devang Patel
In this experimental mode try avoiding debug info emission for classes as much as possible. The goal is to reduce size of produced debuginfo without reducing quality of debug info in general. This is a work in progress. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115188 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-30Added two new command line arguments:Marcin Swiderski
-cfg-add-implicit-dtors - sets CFG::BuildOptions::AddImplicitDtors for AnalysisCosumer to true, -cfg-add-initializers - sets CFG::BuildOptions::AddInitializers for AnalysisCosumer to true. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115142 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-17Use a temporary file for output which gets renamed after all the writing is ↵Argyrios Kyrtzidis
finished. This mainly prevents failures and/or crashes when multiple processes try to read/write the same PCH file. (rdar://8392711&8294781); suggestion & review by Daniel! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114187 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-10Added AnalyzerStatsChecker, a path sensitive check that reports visitation ↵Tom Care
statistics about analysis. Running clang with the -analyzer-stats flag will emit warnings containing the information. We can then run a postanalysis script to take this data and give useful information about how much the analyzer missed in a project. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113568 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-09Frontend: Add -cxx-system-include option which can be used to specify anDaniel Dunbar
explicit list for the C++ system include directories at the -cc1 level, as an alternative to the horrible AddDefaultCPlusPlusIncludePaths(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113505 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-26De-memberify the VarDecl and FunctionDecl StorageClass enums.John McCall
This lets us remove Sema.h's dependency on Expr.h and Decl.h. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112156 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-25GCC didn't care for my attempt at API compatibility, so brute-force everythingJohn McCall
to the new constants. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112047 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-24Frontend: Add basic -H support.Daniel Dunbar
- I didn't implement the GCC "multiple include guard" detection parts, because it doesn't seem useful or obvious. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111983 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-24correct the -isystem option to not add the -isysroot path. Only the weirdChris Lattner
-iwithsysroot flag should do that. This fixes rdar://8345942 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111979 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-24Move ExecuteCompilerInvocation to a new library FrontendToolPeter Collingbourne
r110903 introduced a dependency from Frontend to every library that declared an Action by introducing Action references that previously resided in the driver in the file ExecuteCompilerInvocation.cpp. This patch moves ExecuteCompilerInvocation to a new library named FrontendTool which is intended to bear these dependencies. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111873 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-23Introduce new libclang API functions that determine the availabilityDouglas Gregor
of a cursor or code-completion result, e.g., whether that result refers to an unavailable, deleted, or deprecated declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111858 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-20When performing code-completion in the presence of a preamble, makeDouglas Gregor
sure to (1) actually use the remapped files we were given rather than old data, and (2) keep the remapped files alive until the code-completion results are destroyed. Big thanks to Daniel for the test case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111597 91177308-0d34-0410-b5e6-96231b3b80d8

convoluted and a bit leaky. Now, the Diagnostic object owns its DiagnosticClient. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111437 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-17Create a new Serialization module that contains all the PCH code, and will ↵Sebastian Redl
contain all the module code in the future. Update the Makefiles, CMake projects and the Xcode project. I hope I did everything right for Xcode. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111258 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-17When the # of top-level declarations changes after reparsing aDouglas Gregor
translation unit, refresh code-completion results because they've probably changed. However, enforce a cooldown period between refreshes, to avoid thrashing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111218 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-16Implement name hiding of cached global code-completion results.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111184 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16Add two options for playing with modules.Sebastian Redl
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111166 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16When caching code completions for global declarations, keep track ofDouglas Gregor
the usage type of each declaration result, then compare those types to the preferred type of the completion. This provides parity in the priority calculation between the code-completion results produced directly from Sema and those cached by ASTUnit. For the standard Cocoa.h (+ others) example, there's a penalty of 3-4 hundredeths of a second when caching the global results (for ~31,000 results), because we need an ASTContext-agnostic representation of types for the comparison, and therefore we use... strings. Eventually, we'd like to implement a more efficient ASTContext-agnostic encoding of types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111165 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16Dereferencing NULL pointers is such poor form.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111150 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16When caching global completion results, keep track of the simplifiedDouglas Gregor
type class, so that we can adjust priorities appropriately when the preferred type for the context and the actual type of the completion are similar. This gets us one step closer to parity of the cached completion results with the non-cached completion results. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111139 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-15Extend the code-completion caching infrastructure to include globalDouglas Gregor
declarations (in addition to macros). Each kind of declaration maps to a certain set of completion contexts, and the ASTUnit completion logic introduces the completion strings for those declarations if the actual code-completion occurs in one of the contexts where it matters. There are a few new code-completion-context kinds. Without these, certain completions (e.g., after "using namespace") would need to suppress all global completions, which would be unfortunate. Note that we don't get the priorities right for global completions, because we don't have enough type information. We'll need a way to compare types in an ASTContext-agnostic way before this can be implemented. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111093 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-15DependentTypeOfExprType and DependentDecltypeType are not seen by client code.Argyrios Kyrtzidis
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111090 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
2010-08-13Change Sema's UnusedStaticFuncs to UnusedFileScopedDecls to allow also ↵Argyrios Kyrtzidis
keeping track of unused file scoped variables. This is only preparation, currently only static function definitions are tracked, as before. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111025 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-13Add a new cc1 option -fix-what-you-can which when combined with the fix-it modeNick Lewycky
will apply all fixes even when there were other errors in the file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111020 91177308-0d34-0410-b5e6-96231b3b80d8
