2009-02-04Some name-lookup-related fixes, from Piotr Rak!Douglas Gregor
- Changes Lookup*Name functions to return NamedDecls, instead of Decls. Unfortunately my recent statement that it will simplify lot of code, was not quite right, but it simplifies some... - Makes MergeLookupResult SmallPtrSet instead of vector, following Douglas suggestions. - Adds %qN format for printing qualified names to Diagnostic. - Avoids searching for using-directives in Scopes, which are not DeclScope, during unqualified name lookup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63739 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-04Implement handling of file entry/exit notifications from GNUChris Lattner
line markers, including maintenance of the virtual include stack. For something like this: # 42 "bar.c" 1 # 142 "bar2.c" 1 #warning zappa # 92 "bar.c" 2 #warning gonzo # 102 "foo.c" 2 #warning bonkta we now produce these three warnings: #1: In file included from foo.c:3: In file included from bar.c:42: bar2.c:143:2: warning: #warning zappa #warning zappa ^ #2: In file included from foo.c:3: bar.c:92:2: warning: #warning gonzo #warning gonzo ^ #3: foo.c:102:2: warning: #warning bonkta #warning bonkta ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63722 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-04add the difference in the line marker phys line number and theChris Lattner
query point to the returned presumed location. We now produce: foo.h:92:2: warning: #warning blarg! #warning blarg! ^ foo.h:93:2: warning: #warning blarg! #warning blarg! ^ foo.h:94:2: warning: #warning blarg! #warning blarg! ^ for: #line 92 "foo.h" #warning blarg! #warning blarg! #warning blarg! blarg indeed! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63710 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-04add really really trivial #line support, where #line now makes every Chris Lattner
location below it report as coming from the #line location. For example, with: #line 92 "foo.h" #warning blarg! #warning blarg! we now emit: foo.h:92:2: warning: #warning blarg! #warning blarg! ^ foo.h:92:2: warning: #warning blarg! #warning blarg! ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63709 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-04lower the interface to getLineNumber like we did forChris Lattner
getColumnNumber. This fixes a FIXME in SourceManager::getPresumedLoc because we now just decompose the sloc once. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63701 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-04make SM::getColumnNumber take a predecomposed FileID/offset, whichChris Lattner
makes it clear to clients that they have to pick an instantiation or spelling location before calling it and allows optimization based on that. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63698 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-03more plumbing for #line propagation. Use happy bit #3 Chris Lattner

2009-02-03reclaim my precious bit in FileInfo by ensuring that ContentCache objectsChris Lattner
are 8-byte aligned. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63630 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-03switch SourceManager from using an std::map and std::list of Chris Lattner
ContentCache objects to using a densemap and list, and allocating the ContentCache objects from a bump pointer. This does not speed up or slow down things substantially, but gives us control over their alignment. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63628 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-29next round of diagnostics cleanups, moving some Chris Lattner

2009-01-27If an input constraint refers to an output constraint, it should have the ↵Anders Carlsson
same constraint info as the output constraint. Fixes PR3417 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63127 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-27Split the single monolithic DiagnosticKinds.def file into oneChris Lattner
.def file for each library. This means that adding a diagnostic to sema doesn't require all the other libraries to be rebuilt. Patch by Anders Johnsen! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63111 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-27Introduce a new PresumedLoc class to represent the concept of a locationChris Lattner
as reported to the user and as manipulated by #line. This is what __FILE__, __INCLUDE_LEVEL__, diagnostics and other things should follow (but not dependency generation!). This patch also includes several cleanups along the way: - SourceLocation now has a dump method, and several other places that did similar things now use it. - I cleaned up some code in AnalysisConsumer, but it should probably be simplified further now that NamedDecl is better. - TextDiagnosticPrinter is now simplified and cleaned up a bit. This patch is a prerequisite for #line, but does not actually provide any #line functionality. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63098 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-27make -print-stats print stats about the amount of the SLoc Chris Lattner
address space we used up. Some interesting data: For c99-intconst-1.c: 6912762 SLocEntry's allocated, 25592386B of Sloc address space used. For cocoa.h: 26469 SLocEntry's allocated, 10278752B of Sloc address space used. For carbon.h: 27364 SLocEntry's allocated, 12398141B of Sloc address space used. Clearly 2G of sloc address space should be enough for anyone?! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63093 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-26make getInstantiationLoc and getSpellingLoc handle multiply instantiatedChris Lattner
locations, and move the slow case out of line. No perf change on cocoa.h git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63033 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26fix a negated conditional in getDecomposedInstantiationLocSlowCase,Chris Lattner
which I think is rdar://6527005, and make getDecomposedSpellingLocSlowCase handle nested spelling locations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63030 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-26Check in the long promised SourceLocation rewrite. This lays theChris Lattner
ground work for implementing #line, and fixes the "out of macro ID's" problem. There is nothing particularly tricky about the code, other than the very performance sensitive SourceManager::getFileID() method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62978 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62923 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-23Added virtual method DiagnosticClient::IncludeInDiagnosticCounts(). This is ↵Ted Kremenek
used by Diagnostics to determine if a diagnostic sent to a given DiagnosticClient should be included in the count of diagnostics. The default implementation of this method returns 'true'. Implemented DiagCollector::IncludeInDiagnosticCounts() to return 'false' so that the batching of diagnostics for use with BugReporter doesn't mess up the count of real diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62873 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-21Add a bit to IdentifierInfo that acts as a simple predicate whichChris Lattner
tells us whether Preprocessor::HandleIdentifier needs to be called. Because this method is only rarely needed, this saves a call and a bunch of random checks. This drops the time in HandleIdentifier from 3.52ms to .98ms on cocoa.h on my machine. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62675 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-20Fix: <rdar://problem/6510344> [pth] PTH slows down regular lexer ↵Ted Kremenek
considerably (when it has substantial work) Changes to IdentifierTable: - High-level summary: StringMap never owns IdentifierInfos. It just references them. - The string map now has StringMapEntry<IdentifierInfo*> instead of StringMapEntry<IdentifierInfo>. The IdentifierInfo object is allocated using the same bump pointer allocator as used by the StringMap. Changes to IdentifierInfo: - Added an extra pointer to point to the StringMapEntry<IdentifierInfo*> in the string map. This pointer will be null if the IdentifierInfo* is *only* used by the PTHLexer (that is it isn't in the StringMap). Algorithmic changes: - Non-PTH case: IdentifierInfo::get() will always consult the StringMap first to see if we have an IdentifierInfo object. If that StringMapEntry references a null pointer, we allocate a new one from the BumpPtrAllocator and update the reference in the StringMapEntry. - PTH case: We do the same lookup as with the non-PTH case, but if we don't get a hit in the StringMap we do a secondary lookup in the PTHManager for the IdentifierInfo. If we don't find an IdentifierInfo we create a new one as in the non-PTH case. If we do find and IdentifierInfo in the PTHManager, we update the StringMapEntry to refer to it so that the IdentifierInfo will be found on the next StringMap lookup. This way we only do a binary search in the PTH file at most once for a given IdentifierInfo. This greatly speeds things up for source files containing a non-trivial amount of code. Performance impact: While these changes do add some extra indirection in IdentifierTable to access an IdentifierInfo*, I saw speedups even in the non-PTH case as well. Non-PTH: For -fsyntax-only on Cocoa.h, we see a 6% speedup. PTH (with Cocoa.h in token cache): 11% speedup. I also did an experiment where we did -fsyntax-only on a source file including a large header and Cocoa.h, but the token cache did not contain the larger header. For this file, we were seeing a performance *regression* when using PTH of 3% over non-PTH. Now we are seeing a performance improvement of 9%! Tests: The serialization tests are now failing. I looked at this extensively, and I my belief is that this change is unmasking a bug rather than introducing a new one. I have disabled the serialization tests for now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62636 91177308-0d34-0410-b5e6-96231b3b80d8
