* Driver, Frontend: add CUDA language supportPeter Collingbourne2010-12-011-0/+8

* Add -cc1 -ast-dump-xml, an excessively detailed XML dump of the internalsJohn McCall2010-11-241-0/+3
| | | | | | | | | | | | | of the ASTs. Only available in assertions builds. No stability guarantee. This is intended solely as a debugging tool. I'm not sure if the goals are sufficiently aligned with the XML printer to allow a common implementation. Currently just falls back on the StmtDumper to display statements, which means it doesn't produce valid XML in those cases. llvm-svn: 120088
* now the FileManager has a FileSystemOpts ivar, stop threadingChris Lattner2010-11-231-8/+5
| | | | | | | | | FileSystemOpts through a ton of apis, simplifying a lot of code. This also fixes a latent bug in ASTUnit where it would invoke methods on FileManager without creating one in some code paths in cindextext. llvm-svn: 120010
* give FileManager a 'FileSystemOptions' ivar, which will be usedChris Lattner2010-11-231-1/+1
| | | | | | | to simplify a bunch of code in it. It should ultimately get inlined into FileManager. llvm-svn: 120007

| | | | | | | | | | definitions if they take by-value or return by-value any POD that is larger than some threshold (default is 64 bytes). Implements rdar://8548050. llvm-svn: 119583
* Implement -working-directory.Argyrios Kyrtzidis2010-11-031-2/+26
| | | | | | | | | | | | | | | | | | | 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. Addresses rdar://8583824. llvm-svn: 118203
* Substantially revise how clang computes the visibility of a declaration toJohn McCall2010-10-221-6/+6
| | | | | | | | more closely parallel the computation of linkage. This gets us to a state much closer to what gcc emits, modulo bugs, which will undoubtedly arise in abundance. llvm-svn: 117147
* Reorganize predefined macros for all Windows targets.Michael J. Spencer2010-10-211-0/+3
| | | | | | | | | | This adds an option to set the _MSC_VER macro without recompiling. This is very useful when testing compatibility with the Windows SDK and c++stdlib headers. -fmsc-version=<version> (defaults to VS2003 (1300)) llvm-svn: 116999

* "Fix" bogus idempotent operations warning due to loop unrolling not ↵Ted Kremenek2010-10-181-1/+1
| | | | | | | | | | unrolling enough loops to show that an invariant doesn't hold. This fix is to increase the loop unrolling count to 4, which experiments show doesn't typically impact analysis time. The real fix is to modify the IdempotentOperationsChecker to suppress warnings where an analysis point could be preceded by a point where we gave up due to loop unrolling. llvm-svn: 116769
* Wire up the -fstrict-aliasing and -fno-strict-aliasing optionsDan Gohman2010-10-141-0/+1

* Introduce command line option -error-on-deserialized-decl that is ↵Argyrios Kyrtzidis2010-10-141-0/+6
| | | | | | | | | | 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. llvm-svn: 116505
* Introduce command line option -dump-deserialized-decls which is used to ↵Argyrios Kyrtzidis2010-10-141-0/+1

* Eliminate the (de-)serialization of code completion results, now thatDouglas Gregor2010-10-111-4/+0
| | | | | | libclang does not support out-of-process code completion. llvm-svn: 116253
* Eliminate -fdiagnostics-binary and all of the infrastructure forDouglas Gregor2010-10-111-3/+0
| | | | | | | | 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. llvm-svn: 116250

* Introduce -flimit-debug-info.Devang Patel2010-09-301-0/+1
| | | | | | 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. llvm-svn: 115188
* Added two new command line arguments:Marcin Swiderski2010-09-301-0/+2
| | | | | | | -cfg-add-implicit-dtors - sets CFG::BuildOptions::AddImplicitDtors for AnalysisCosumer to true, -cfg-add-initializers - sets CFG::BuildOptions::AddInitializers for AnalysisCosumer to true. llvm-svn: 115142
* Add a -ftrapv-handler= option which allows a handler to invoke instead of ↵David Chisnall2010-09-171-2/+11
| | | | | | simply aborting when a signed operation overflows. This mirrors the (GCC-incompatible) behaviour from clang 1.0 and 1.1 when -ftrapv was specified, but allows the handler to be defined for each compilation unit. llvm-svn: 114192
* Added AnalyzerStatsChecker, a path sensitive check that reports visitation ↵Tom Care2010-09-101-0/+3
| | | | | | 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. llvm-svn: 113568
* Frontend: Add -cxx-system-include option which can be used to specify anDaniel Dunbar2010-09-091-0/+6
| | | | | | | explicit list for the C++ system include directories at the -cc1 level, as an alternative to the horrible AddDefaultCPlusPlusIncludePaths(). llvm-svn: 113505

| | | | | | (original patch r112791 was reverted due to a bug). llvm-svn: 112915

* Frontend: Add basic -H support.Daniel Dunbar2010-08-241-2/+5
| | | | | | | - I didn't implement the GCC "multiple include guard" detection parts, because it doesn't seem useful or obvious. llvm-svn: 111983
* correct the -isystem option to not add the -isysroot path. Only the weirdChris Lattner2010-08-241-6/+7
| | | | | | -iwithsysroot flag should do that. This fixes rdar://8345942 llvm-svn: 111979
* Implement -iwithsysroot, an apple extension which is a close cousin of -isystem.Chris Lattner2010-08-241-1/+1
| | | | | | | Instead of implementing -isystem, I accidentally implemented this cousin. Next up is to implement -isystem right. llvm-svn: 111966
* Abstract out member-pointer creation. I'm really unhappy about the currentJohn McCall2010-08-221-6/+4
| | | | | | | | duplication between the constant and non-constant paths in all of this. Implement ARM ABI semantics for member pointer constants and conversion. llvm-svn: 111772

* Create a new Serialization module that contains all the PCH code, and will ↵Sebastian Redl2010-08-171-1/+1
| | | | | | 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. llvm-svn: 111258

* Extend the code-completion caching infrastructure to include globalDouglas Gregor2010-08-151-0/+4
| | | | | | | | | | | | | | | | | | 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. llvm-svn: 111093
* Add a new cc1 option -fix-what-you-can which when combined with the fix-it modeNick Lewycky2010-08-131-0/+3
| | | | | | will apply all fixes even when there were other errors in the file. llvm-svn: 111020
* Just disable the hidden-visibility optimization for now by hiding it behindJohn McCall2010-08-121-0/+1
| | | | | | | | a -cc1 option. The Darwin linker complains about mixed visibility when linking gcc-built objects with clang-built objects, and the optimization isn't really that valuable. Platforms with less ornery linkers can feel free to enable this. llvm-svn: 110979

| | | | | | | | | to a flag (-analyzer-check-idempotent-operations) - Added IdempotentOperationChecker to experimental analyses for testing purposes - Updated test cases to explictly call the checker llvm-svn: 110482
* Add -cc1 option '-unoptimized-cfg' to toggle using a CFG (for static ↵Ted Kremenek2010-08-031-0/+1

* Implement -fno-validate-pch at the -cc1 level, which suppresses mostDouglas Gregor2010-07-271-1/+2
| | | | | | | | | | | | | | | of the usual consistency checks used to determine when a precompiled header is incompatible with the translation unit it's being loaded into. Enable this option when loading a precompiled preamble, because the preamble loader will be performing all of this checking itself. Enable the preamble-based test now that it's working. This option is also useful for debugging Clang's PCH (<rdar://problem/7532213>). llvm-svn: 109475
* Introduce basic support for loading a precompiled preamble whileDouglas Gregor2010-07-261-0/+17
| | | | | | | | | | | | | | | | | | | | | | | reparsing an ASTUnit. When saving a preamble, create a buffer larger than the actual file we're working with but fill everything from the end of the preamble to the end of the file with spaces (so the lexer will quickly skip them). When we load the file, create a buffer of the same size, filling it with the file and then spaces. Then, instruct the lexer to start lexing after the preamble, therefore continuing the parse from the spot where the preamble left off. It's now possible to perform a simple preamble build + parse (+ reparse) with ASTUnit. However, one has to disable a bunch of checking in the PCH reader to do so. That part isn't committed; it will likely be handled with some other kind of flag (e.g., -fno-validate-pch). As part of this, fix some issues with null termination of the memory buffers created for the preamble; we were trying to explicitly NULL-terminate them, even though they were also getting implicitly NULL terminated, leading to excess warnings about NULL characters in source files. llvm-svn: 109445
* Eliminate the "minimal" and printing parser actions, which only everDouglas Gregor2010-07-261-6/+0

* Introduce a new lexer function to compute the "preamble" of a file,Douglas Gregor2010-07-201-0/+3
| | | | | | | | | which is the part of the file that contains all of the initial comments, includes, and preprocessor directives that occur before any of the actual code. Added a new -print-preamble cc1 action that is only used for testing. llvm-svn: 108913
