* More refactoring of common API to the common class forFariborz Jahanian2009-01-221-93/+104
| | | | | | the two Next's objc runtimes. More comments. llvm-svn: 62735
* Allow creation of "dummy" compile units for debug information.Daniel Dunbar2009-01-221-10/+13
| | | | | | | | - Although gross, this is needed currently to ensure that we produce well formed debug information (to match pace with the assertions being added to DebugInfo in LLVM). llvm-svn: 62734
* Moved whole bunch of common APIs to the common class.Fariborz Jahanian2009-01-211-37/+37
| | | | | | No change in functionality. llvm-svn: 62729
* Combine two branches into one. No functionality change.Ted Kremenek2009-01-211-3/+1

* Fix <rdar://problem/6512717> by correctly reading the right offset in the ↵Ted Kremenek2009-01-211-1/+1
| | | | | | token data in PTHLexer::getSourceLocation(). llvm-svn: 62725
* Fix Sema::Owned(ExprResult) to not use a ternary operator. Necessary to work ↵Steve Naroff2009-01-211-1/+3
| | | | | | | | around a Visual Studio compiler bug. Thanks to Doug Gregor for the suggestion. llvm-svn: 62723
* Static Analyzer: Replace LiveSymbols/DeadSymbols sets with a new object ↵Ted Kremenek2009-01-218-84/+83
| | | | | | called "SymbolReaper". Right now it just consolidates the two and cleans up some client code, but shortly it will be used to enable "lazy computation" of live symbols for use with RegionStore. llvm-svn: 62722
* Refactoring ObjC Next's runtime classes in preparation forFariborz Jahanian2009-01-213-75/+126
| | | | | | the new ObjC's abi. llvm-svn: 62721
* Inline ParseOptionalTypeSpecifier into ParseDeclarationSpecifiers. Chris Lattner2009-01-211-9/+108
| | | | | | | This avoids call overhead and extraneous switches when parsing very simple declspecs like "int" "void" etc, which are pretty common :) llvm-svn: 62711
* revert the gnu objc patches, they regress codegen-gnu.mChris Lattner2009-01-211-11/+7
| | | | llvm-svn: 62708
* switch from getTypeAtIndex to getElementType. It is non-virtualChris Lattner2009-01-211-1/+1
| | | | | | and more idiomatic. llvm-svn: 62705
* ParseOptionalTypeSpecifier should consume a token if it returns true.Chris Lattner2009-01-211-4/+5
| | | | llvm-svn: 62704
* Fix objc type conversion issues with the GNU runtime, patch byChris Lattner2009-01-211-7/+11

* merge two checks for identifiers in the pth loop into one.Chris Lattner2009-01-211-9/+10
| | | | llvm-svn: 62677
* a trivial micro optimization to save a load.Chris Lattner2009-01-211-2/+2
| | | | llvm-svn: 62676
* Add a bit to IdentifierInfo that acts as a simple predicate whichChris Lattner2009-01-215-4/+15
| | | | | | | | | 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. llvm-svn: 62675
* silence a couple unused variable 'result' warnings.Chris Lattner2009-01-211-2/+2
| | | | llvm-svn: 62674
* Don't crash on empty PTH files. This fixes <rdar://problem/6512714>.Ted Kremenek2009-01-211-9/+19

* minor cleanups: now that tokens are 4-byte aligned in a PTH Chris Lattner2009-01-211-22/+6
| | | | | | file, just load them directly as ints. llvm-svn: 62668
* Get RegionStore to work with the retain/release checker and its test cases.Ted Kremenek2009-01-211-20/+16
| | | | | | Because the RegionStore can reason about values beyond the reasoning power of BasicStore, this patch splits some of the test cases for the retain/release checker to have versions that are handled by RegionStore (more warnings) and BasicStore (less warnings). llvm-svn: 62667
* Fix an inline asm sema bug that I introduced.Anders Carlsson2009-01-211-2/+2
| | | | llvm-svn: 62666
* Don't look up decls with no name (such as parameters and unnamed tagged types),Chris Lattner2009-01-211-13/+15
| | | | | | this removes 4266 calls to LookupDecl. llvm-svn: 62662

* Fix: <rdar://problem/6510344> [pth] PTH slows down regular lexer ↵Ted Kremenek2009-01-202-15/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 62636
* Provide a placement new taking an ASTContext argument.Sebastian Redl2009-01-201-8/+6
| | | | | | | This allows more concise syntax when allocating an object using the ASTContext's allocator. Convert a few allocations to this operator to for test purposes. llvm-svn: 62623

* Fix a crash Anders' was seeing due to free'ing an invalid pointerChris Lattner2009-01-201-12/+2
| | | | | | caused by my previous commit. llvm-svn: 62613
* Convert more exprs to use ASTContext's Allocator.Steve Naroff2009-01-201-11/+18
| | | | | | | | When using a BumpPtrAllocator, this reduces malloc overhead from 2.2->1.9% (for Cocoa.h). At this point, malloc() has dropped the fourth most expensive routine (behind Preprocessor::HandleIdentifier()). llvm-svn: 62612

* Optimize Declarator to avoid malloc/free traffic for the argument list of aChris Lattner2009-01-204-5/+44
| | | | | | | | | | | | | | | | function DeclaratorChunk in common cases. This uses a fixed array in Declarator when it is small enough for the first function declarator chunk in a declarator. This eliminates all malloc/free traffic from DeclaratorChunk::getFunction when running on Cocoa.h except for five functions: signal/bsd_signal/sigset, which have multiple Function DeclChunk's, and CFUUIDCreateWithBytes/CFUUIDGetConstantUUIDWithBytes, which take more than 16 arguments. This patch was pair programmed with Steve. llvm-svn: 62599

| | | | | | | | | va_list is a struct, like x86-64. If anyone has a better idea for how to do the check in the if statements, suggestions are welcome. llvm-svn: 62582

* Fix for PR3350: add special-casing for "references" to va_lists in Eli Friedman2009-01-202-5/+18
| | | | | | | | builtins. Also, a minor tweak to va_copy for consistency. llvm-svn: 62574
* Remove the TopLevelDecls from TranslationUnit, since all of those decls are ↵Douglas Gregor2009-01-204-114/+10
| | | | | | owned by the ASTContext's TranslationUnitDecl. There are definitely some leaking Decls now that I'll tackle tomorrow llvm-svn: 62568
* Remove ScopedDecl, collapsing all of its functionality into Decl, soDouglas Gregor2009-01-2027-450/+305
| | | | | | | | | | | | | | | | that every declaration lives inside a DeclContext. Moved several things that don't have names but were ScopedDecls (and, therefore, NamedDecls) to inherit from Decl rather than NamedDecl, including ObjCImplementationDecl and LinkageSpecDecl. Now, we don't store empty DeclarationNames for these things, nor do we try to insert them into DeclContext's lookup structure. The serialization tests are temporarily disabled. We'll re-enable them once we've sorted out the remaining ownership/serialiazation issues between DeclContexts and TranslationUnion, DeclGroups, etc. llvm-svn: 62562

* PTH: Emitted tokens now consist of 12 bytes that are loaded used 3 32-bit ↵Ted Kremenek2009-01-191-5/+8
| | | | | | loads. This reduces user time but increases system time because of the slightly larger PTH file. Although there is no performance win on Cocoa.h and -Eonly, overall this seems like a good step. llvm-svn: 62542
* Make sure all types are allocated with 8-byte alignment.Steve Naroff2009-01-191-21/+21
| | | | | | The QualType smart pointer assumes we have 3 flag bits available. llvm-svn: 62540
