2016-10-07[analyzer] Re-apply r283092, attempt no.4, chunk no.4 (last)Artem Dergachev1-2/+7
The problem that caused the msvc crash has been indentified and fixed in the previous commit. This patch contains the rest of r283092. llvm-svn: 283584
2016-10-07Revert "[analyzer] Try to re-apply r283092 "Extend bug reports with extra notes"Artem Dergachev1-7/+2
Vector of smart pointers wasn't the thing that caused msvc crash. llvm-svn: 283537
2016-10-07[analyzer] Try to re-apply r283092 "Extend bug reports with extra notes"Artem Dergachev1-2/+7
Replace SmallVector<IntrusiveRefCntPtr> with a vector of plain pointers. Would insignificantly increase memory usage. llvm-svn: 283536

2016-10-03[analyzer] Extend bug reports with extra notesArtem Dergachev1-2/+7
These diagnostics are separate from the path-sensitive engine's path notes, and can be added manually on top of path-sensitive or path-insensitive reports. The new note diagnostics would appear as note:-diagnostic on console and as blue bubbles in scan-build. In plist files they currently do not appear, because format needs to be discussed with plist file users. The analyzer option "-analyzer-config notes-as-events=true" would convert notes to normal path notes, and put them at the beginning of the path. This is a temporary hack to show the new notes in plist files. A few checkers would be updated in subsequent commits, including tests for this new feature.

This fixes rounded corners and shadows of analyzer diagnostic pieces in browsers such as Firefox. Differential Revision: https://reviews.llvm.org/D23272 llvm-svn: 281625
2016-02-09Simplify EnterTokenStream API to make it more robust for memory managementDavid Blaikie1-1/+1
While this won't help fix things like the bug that r260219 addressed, it seems like good tidy up to have anyway. (it might be nice if "makeArrayRef" always produced a MutableArrayRef & let it decay to an ArrayRef when needed - then I'd use that for the MutableArrayRefs in this patch) If we had std::dynarray I'd use that instead of unique_ptr+size_t, ideally (but then it'd have to be threaded down through the Preprocessor all the way - no idea how painful that would be) llvm-svn: 260246
2014-07-16Make clang's rewrite engine a core featureAlp Toker1-0/+582
The rewrite facility's footprint is small so it's not worth going to these lengths to support disabling at configure time, particularly since key compiler features now depend on it. Meanwhile the Objective-C rewriters have been moved under the ENABLE_CLANG_ARCMT umbrella for now as they're comparatively heavy and still potentially worth excluding from lightweight builds. Tests are now passing with any combination of feature flags. The flags historically haven't been tested by LLVM's build servers so caveat emptor. llvm-svn: 213171
2012-09-01Split library clangRewrite into clangRewriteCore and clangRewriteFrontend.Ted Kremenek1-583/+0
This is similar to how we divide up the StaticAnalyzer libraries to separate core functionality to what is clearly associated with Frontend actions. llvm-svn: 163050
2012-08-02[analyzer] Add Prev/Next links to the HTML output.Jordan Rose1-1/+2
llvm-svn: 161153
2012-06-08Disable _Pragma during HTML macro rewriting to keep from crashing.Jordan Rose1-1/+7
The preprocessor's handling of diagnostic push/pops is stateful, so encountering pragmas during a re-parse causes problems. HTMLRewrite already filters out normal # directives including #pragma, so it's clear it's not expected to be interpreting pragmas in this mode. This fix adds a flag to Preprocessor to explicitly disable pragmas. The "right" fix might be to separate pragma lexing from pragma parsing so that we can throw away pragmas like we do preprocessor directives, but right now it's important to get the fix in. Note that this has nothing to do with the "hack" of re-using the input preprocessor in HTMLRewrite. Even if we someday copy the preprocessor instead of re-using it, the copy would (and should) include the diagnostic level tables and have the same problems. llvm-svn: 158214
2012-03-11Unify naming of LangOptions variable/get function across the Clang stack ↵David Blaikie1-2/+2
(Lex to AST). The member variable is always "LangOpts" and the member function is always "getLangOpts". Reviewed by Chris Lattner llvm-svn: 152536
2012-03-06User-defined literals: reject string and character UDLs in all places where theRichard Smith1-0/+1
grammar requires a string-literal and not a user-defined-string-literal. The two constructs are still represented by the same TokenKind, in order to prevent a combinatorial explosion of different kinds of token. A flag on Token tracks whether a ud-suffix is present, in order to prevent clients from needing to look at the token's spelling. llvm-svn: 152098
2012-02-07Revert my patches which removed Diagnostic.h includes by moving some ↵Benjamin Kramer1-1/+0
operator overloads out of line. This seems to negatively affect compile time onsome ObjC tests (which use a lot of partial diagnostics I assume). I have to come up with a way to keep them inline without including Diagnostic.h everywhere. Now adding a new diagnostic requires a full rebuild of e.g. the static analyzer which doesn't even use those diagnostics. This reverts commit 6496bd10dc3a6d5e3266348f08b6e35f8184bc99. This reverts commit 7af19b817ba964ac560b50c1ed6183235f699789. This reverts commit fdd15602a42bbe26185978ef1e17019f6d969aa7. This reverts commit 00bd44d5677783527d7517c1ffe45e4d75a0f56f.

we have the ability to create a new, distict diagnostic consumer when we go off and build a module. This avoids the currently horribleness where the same diagnostic consumer sees diagnostics for multiple translation units (and multiple SourceManagers!) causing all sorts of havok. llvm-svn: 140743

SourceManager's getBuffer() (and similar) operations. This abstract can be used to force callers to cope with errors in getBuffer(), such as missing files and changed files. Fix a bunch of callers to use the new interface. Add some very basic checks for file consistency (file size, modification time) into ContentCache::getBuffer(), although these checks don't help much until we've updated the main callers (e.g., SourceManager::getSpelling()). llvm-svn: 98585
