2016-03-01Optionally demote fatal errors to non-fatal errors.Manuel Klimek1-0/+2
This behavior is enabled when the new CXTranslationUnit_KeepGoing option is passed to clang_parseTranslationUnit{,2}. It is geared towards use by IDEs and similar consumers of the clang-c API where fatal errors may arise when parsing incomplete code mid-edit, or when include paths are not properly configured yet. In such situations one still wants to get as much information as possible about a TU. Previously, the semantic analysis would not instantiate templates or report additional fatal errors after the first fatal error was encountered. Fixes PR24268. Patch by Milian Wolff. llvm-svn: 262318

2016-01-06Show inclusions from a preamble in clang_getInclusions.Erik Verbruggen1-0/+21
When reparsing a translation unit with preamble generation turned on, no includes are found. This is due to the fact that all SLocs from AST/PCH files are skipped as they are 'loaded', and inclusions from a preamble are also 'loaded'. So, in case a file has a preamble, it first needs to process those loaded inclusions, and then check for any local inclusions. This latter one is for any includes that are not part of the preamble, like includes half-way through a file. This fixes PR24748.

2015-12-15[libclang] Add a flag to create the precompiled preamble on the first parse.Benjamin Kramer1-1/+3
Summary: The current default is to create the preamble on the first reparse, aka second parse. This is useful for clients that do not want to block when opening a file because serializing the preamble takes a bit of time. However, this makes the reparse much more expensive and that may be on the critical path as it's the first interaction a user has with the source code. YouCompleteMe currently optimizes for the first code interaction by parsing the file twice when loaded. That's just unnecessarily slow and this flag helps to avoid that.

2015-11-23Make clang_Cursor_getMangling not mangle if the declaration isn't mangledEhsan Akhgari1-0/+30
Right now clang_Cursor_getMangling will attempt to mangle any declaration, even if the declaration isn't mangled (extern C). This results in a partially mangled name which isn't useful for much.

2014-06-05Flush C stdio streams upon process terminationReid Kleckner1-3/+9
Due to what can only be described as a CRT bug, stdout and amazingly even stderr are not always flushed upon process termination, especially when the system is under high threading pressure. I have found two repros for this: 1) In lib\Support\Threading.cpp, change sys::Mutex to an std::recursive_mutex and run check-clang. Usually between 30 and 40 tests will fail. 2) Add OutputDebugStrings in code that runs during static initialization and static shutdown. This will sometimes generate similar failures. After a substantial amount of troubleshooting and debugging, I found that I could reproduce this from the command line without running check-clang. Simply make the mutex change described in #1, then manually run the following command many times by running it once, then pressing Up -> Enter very quickly: D:\src\llvm\build\vs2013\Debug\bin\c-index-test.EXE -cursor-at=D:\src\llvm\tools\clang\test\Index\targeted-preamble.h:2:15 D:\src\llvm\tools\clang\test\Index\targeted-cursor.c -include D:\src\llvm\build\vs2013\tools\clang\test\Index\Output\targeted-cursor.c.tmp.h -Xclang -error-on-deserialized-decl=NestedVar1 -Xclang -error-on-deserialized-decl=TopVar | D:\src\llvm\build\vs2013\Debug\bin\FileCheck.EXE D:\src\llvm\tools\clang\test\Index\targeted-cursor.c -check-prefix=PREAMBLE-CURSOR1 Sporadically they will fail, and attaching a debugger to a failed instance indicates that stdin of FileCheck.exe is empty. Note that due to the repro in #2, we can rule out a bug in the STL's mutex implementation, and instead conclude that this is a real flake in the windows test harness. Test Plan: Without patch: Ran check-clang 10 times and saw over 30 Unexpected failures on every run. With patch: Ran check-clang 10 times and saw 0 unexpected failures across all runs.

2014-05-10Don't leak CXStrings for replacement fix-its in c-index-test.Nico Weber1-1/+0
The loop body used to contain a switch statement; it looks like r96685 replaced that with an if/else if/else but accidentally left one of the three break statements from the switch behind, skipping the clang_disposeString() call for replacements (and the rest of the loop too, which apparently doesn't make a differences for the test cases we have). r96685: http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20100215/027754.html This too might possibly the last leak in clang (PR19521). llvm-svn: 208483

2014-05-02[leaks] Parse the schema file every time we try to verify the XML. Yes,Chandler Carruth1-29/+16
this is wasteful, blah blah, but this is a test utility only. It turns out that without doing this, libxml2 will always leak a bunch of the XML data, and that is causing failures with LSan. This is also quite a bit simpler and I don't think it is slow enough to really be a show stopper. If someone yells about the runtime of c-index-test, we can do other things to try to mitigate it, but the current strategy wasn't working well. llvm-svn: 207882
2014-04-28libclang: split out the documentation comment APIAlp Toker1-0/+1
It's possible that the "comment AST" may be replaced or split out in the midterm, any anyway this makes the headers easier to read. Developers don't currently need to include "clang-c/Documentation.h" explicitly and there's no macro to test for availability yet. The raw comment and brief comment accessors have been kept in Index.h though brief support may also move here as a separate proposal. This is not a deprecation, just a gentle separation of concerns as we look to simplify the built-in representation of comment nodes and support external comment processors. llvm-svn: 207392
2014-04-26libclang: remove 'CXDiagnostic_Remark'Alp Toker1-1/+0
The change was landed without review or test cases. It trivially broke almost any stable application checking for Severity >= CXDiagnostic_Error or indeed any other kind of severity comparison upon encountering a 'remark'. Mapped to CXDiagnostic_Warning until a workable solution is proposed to the list that preserves API stability. (It's also not clear why the rest of r202475 wasn't simply implemented as a modifier to the existing 'warning' level.) llvm-svn: 207319

2014-02-28Add 'remark' diagnostic type in 'clang'Tobias Grosser1-0/+1
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

2014-02-12libclang: report error code for bad PCH filesDmitri Gribenko1-86/+150
This commit improves libclang to report the error condition when CXTranslationUnit can not be created because of a stale PCH file. This allows the caller, for example, to rebuild the PCH file and retry the request. There two are APIs in libclang that return a CXTranslationUnit and don't support reporting detailed errors (the only error condition is a NULL result). For these APIs, a second, superior, version is introduced -- clang_createTranslationUnit2 and clang_parseTranslationUnit2. These functions return a CXTranslationUnit indirectly and also return an error code. Old functions are still supported and are nothing more than convenience wrappers that ignore extended error codes. As a cleanup, this commit also categorizes some libclang errors in the functions I had to modify anyway. llvm-svn: 201249
2014-02-12Add an option to allow Clang verify source files for a module only once duringDmitri Gribenko1-0/+10
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
