* Add a bit to IdentifierInfo that acts as a simple predicate whichChris Lattner2009-01-216-11/+74
| | | | | | | | | 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

* Get RegionStore to work with the retain/release checker and its test cases.Ted Kremenek2009-01-217-44/+233
| | | | | | 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

| | | | | | | | | | | - For now forces generation of plist files, need to think about the right interface. - Changed -fsyntax-only mode to be its own phase (more consistent). - Add -WA, for passing options verbatim to analyzer. llvm-svn: 62649

* Fix: <rdar://problem/6510344> [pth] PTH slows down regular lexer ↵Ted Kremenek2009-01-205-47/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Redl2009-01-202-10/+47
| | | | | | | 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

* ccc: Allow downstream tools to be aware of final output name.Daniel Dunbar2009-01-203-109/+121
| | | | | | | | | | | | | - This is a hack to allow the Darwin linker to get -final_output when doing universal builds; the mechanism should be generalized. - Handle multiple redundant -arch arguments correctly. - Forward -arch_multiple and -final_output to gcc when necessary. - Simplified implementation of derived gcc tools. llvm-svn: 62618

* 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 Lattner2009-01-205-49/+85
| | | | | | | | | | | | | | | | 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
