* [libclang] Don't pad the main buffer for the preamble.Argyrios Kyrtzidis2014-03-091-40/+6
| | | | | | | | | Padding does not seem to be useful currently, and it leads to bogus location if an error points to the end of the file. rdar://15836513 llvm-svn: 203370

* The Visual Studio IDE changed behavior in VS2012. It used to be the case thatYunzhong Gao2014-03-071-1/+3
| | | | | | | | | | | | | | | | the clang diagnostic has to report a column number one less than the correct value in order for the IDE to move the cursor to the expected location. This behavior is changed in VS2012 and VS2013 so that the IDE is now expecting the column number to match the actual source location. Before: source(line, column-1): type: message After: source(line, column): type: message This patch changes -fdiagnostics-format=msvc to match the new VS2012 and VS2013 when fmsc-version is 1700 or greater.

* Serialized diagnostic severity levels should be stable.Jordan Rose2014-03-031-2/+17
| | | | | | | | | Serialized diagnostics were accidentally using the AST diagnostic level values rather than a dedicated stable enum, so the addition of "remark" broke the reading of existing serialized diagnostics files. I've added a .dia file generated from Xcode 5's Clang to make sure we don't break this in the future. llvm-svn: 202733

* Reapply fixed "Honour 'use-external-names' in FileManager"Ben Langmuir2014-02-281-1/+1
| | | | | | | | | | | | | | | | Was r202442 There were two issues with the original patch that have now been fixed. 1. We were memset'ing over a FileEntry in a test case. After adding a std::string to FileEntry, this still happened to not break for me. 2. I didn't pass the FileManager into the new compiler instance in compileModule. This was hidden in some cases by the fact I didn't clear the module cache in the test. Also, I changed the copy constructor for FileEntry, which was memcpy'ing in a (now) unsafe way. llvm-svn: 202539
* Add 'remark' diagnostic type in 'clang'Tobias Grosser2014-02-283-0/+8
| | | | | | | | | | | | | | | | | | | | | | | A 'remark' is information that is not an error or a warning, but rather some additional information provided to the user. In contrast to a 'note' a 'remark' is an independent diagnostic, whereas a 'note' always depends on another diagnostic. A typical use case for remark nodes is information provided to the user, e.g. information provided by the vectorizer about loops that have been vectorized. This patch provides the initial implementation of 'remarks'. It includes the actual definiton of the remark nodes, their printing as well as basic parameter handling. We are reusing the existing diagnostic parameters which means a remark can be enabled with normal '-Wdiagnostic-name' flags and can be upgraded to an error using '-Werror=diagnostic-name'. '-Werror' alone does not upgrade remarks. This patch is by intention minimal in terms of parameter handling. More experience and more discussions will most likely lead to further enhancements in the parameter handling. llvm-svn: 202475

| | | | | | | | | | | | | | | ASTUnit::getMainBufferWithPrecompiledPreamble(). With r197755 we started reading the contents of buffer file entries, but the buffers may point to ASTReader blobs that have been disposed. Fix this by having the CompilerInstance object keep a reference to the ASTReader as well as having the ASTContext keep reference to the ExternalASTSource. This was very difficult to construct a test case for. rdar://16149782 llvm-svn: 202346

* [CMake] Get rid of explicit dependencies to include/clang/*.inc and ↵NAKAMURA Takumi2014-02-211-16/+0
| | | | | | | | | | | | | | | | | | | introduce CLANG_TABLEGEN_TARGETS. This does; - clang_tablegen() adds each tblgen'd target to global property CLANG_TABLEGEN_TARGETS as list. - List of targets is added to LLVM_COMMON_DEPENDS. - all clang libraries and targets depend on generated headers. You might wonder this would be regression, but in fact, this is little loss. - Almost all of clang libraries depend on tblgen'd files and clang-tblgen. - clang-tblgen may cause short stall-out but doesn't cause unconditional rebuild. - Each library's dependencies to tblgen'd files might vary along headers' structure. It made hard to track and update *really optimal* dependencies. Each dependency to intrinsics_gen and ClangSACheckers is left as DEPENDS. llvm-svn: 201842

* Expand macros in pragmas with -fms-extensions and -EReid Kleckner2014-02-201-36/+7
| | | | | | | | | | | | | | gcc never expands macros in pragmas and MSVC always expands macros before processing pragmas. Clang usually allows macro expansion, except in a handful of pragmas, most of which are handled by the lexer. Also remove PPCallbacks for pragmas that are currently handled in the parser. Without a Parser, such as with clang -E, these callbacks would never be called. Fixes PR18576. llvm-svn: 201821
* Recommit virtual file systemBen Langmuir2014-02-204-7/+16
| | | | | | | | | | | Previously reverted in r201755 due to causing an assertion failure. I've removed the offending assertion, and taught the CompilerInstance to create a default virtual file system inside createFileManager. In the future, we should be able to reach into the CompilerInvocation to customize this behaviour without breaking clients that don't care. llvm-svn: 201818

* MS ABI: Implement #pragma vtordisp() and clang-cl /vdNReid Kleckner2014-02-121-0/+1
| | | | | | | | | | | | | | | | | These features are new in VS 2013 and are necessary in order to layout std::ostream correctly. Currently we have an ABI incompatibility when self-hosting with the 2013 stdlib in our convertible_fwd_ostream wrapper in gtest. This change adds another implicit attribute, MSVtorDispAttr, because implicit attributes are currently the best way to make sure the information stays on class templates through instantiation.

* Add an option to allow Clang verify source files for a module only once duringDmitri Gribenko2014-02-122-18/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | the build When Clang loads the module, it verifies the user source files that the module was built from. If any file was changed, the module is rebuilt. There are two problems with this: 1. correctness: we don't verify system files (there are too many of them, and stat'ing all of them would take a lot of time); 2. performance: the same module file is verified again and again during a single build. This change allows the build system to optimize source file verification. The idea is based on the fact that while the project is being built, the source files don't change. This allows us to verify the module only once during a single build session. The build system passes a flag, -fbuild-session-timestamp=, to inform Clang of the time when the build started. The build system also requests to enable this feature by passing -fmodules-validate-once-per-build-session. If these flags are not passed, the behavior is not changed. When Clang verifies the module the first time, it writes out a timestamp file. Then, when Clang loads the module the second time, it finds a timestamp file, so it can compare the verification timestamp of the module with the time when the build started. If the verification timestamp is too old, the module is verified again, and the timestamp file is updated. llvm-svn: 201224
