2011-02-11Implement AST/PCH chaining support for macro definitions. Previously,Douglas Gregor
we would deserialize all of the macro definitions we knew about while serializing the macro definitions at the end of the AST/PCH file. Even though we skipped most of them (since they were unchanged), it's still a performance problem. Now, we do the standard AST/PCH chaining trick: watch what identifiers are deserialized as macro names, and consider only those identifiers (along with macro definitions that have been deserialized/written in the source) when serializing the preprocessor state. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125324 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-10Implement two related optimizations that make de-serialization ofDouglas Gregor
AST/PCH files more lazy: - Don't preload all of the file source-location entries when reading the AST file. Instead, load them lazily, when needed. - Only look up header-search information (whether a header was already #import'd, how many times it's been included, etc.) when it's needed by the preprocessor, rather than pre-populating it. Previously, we would pre-load all of the file source-location entries, which also populated the header-search information structure. This was a relatively minor performance issue, since we would end up stat()'ing all of the headers stored within a AST/PCH file when the AST/PCH file was loaded. In the normal PCH use case, the stat()s were cached, so the cost--of preloading ~860 source-location entries in the Cocoa.h case---was relatively low. However, the recent optimization that replaced stat+open with open+fstat turned this into a major problem, since the preloading of source-location entries would now end up opening those files. Worse, those files wouldn't be closed until the file manager was destroyed, so just opening a Cocoa.h PCH file would hold on to ~860 file descriptors, and it was easy to blow through the process's limit on the number of open file descriptors. By eliminating the preloading of these files, we neither open nor stat the headers stored in the PCH/AST file until they're actually needed for something. Concretely, we went from *** HeaderSearch Stats: 835 files tracked. 364 #import/#pragma once files. 823 included exactly once. 6 max times a file is included. 3 #include/#include_next/#import. 0 #includes skipped due to the multi-include optimization. 1 framework lookups. 0 subframework lookups. *** Source Manager Stats: 835 files mapped, 3 mem buffers mapped. 37460 SLocEntry's allocated, 11215575B of Sloc address space used. 62 bytes of files mapped, 0 files with line #'s computed. with a trivial program that uses a chained PCH including a Cocoa PCH to *** HeaderSearch Stats: 4 files tracked. 1 #import/#pragma once files. 3 included exactly once. 2 max times a file is included. 3 #include/#include_next/#import. 0 #includes skipped due to the multi-include optimization. 1 framework lookups. 0 subframework lookups. *** Source Manager Stats: 3 files mapped, 3 mem buffers mapped. 37460 SLocEntry's allocated, 11215575B of Sloc address space used. 62 bytes of files mapped, 0 files with line #'s computed. for the same program. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125286 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-09Remove vtables from the Stmt hierarchy; this was pretty easy asJohn McCall
there were only three virtual methods of any significance. The primary way to grab child iterators now is with Stmt::child_range children(); Stmt::const_child_range children() const; where a child_range is just a std::pair of iterators suitable for being llvm::tie'd to some locals. I've left the old child_begin() and child_end() accessors in place, but it's probably a substantial penalty to grab the iterators individually now, since the switch-based dispatch is kindof inherently slower than vtable dispatch. Grabbing them together is probably a slight win over the status quo, although of course we could've achieved that with vtables, too. I also reclassified SwitchCase (correctly) as an abstract Stmt class, which (as the first such class that wasn't an Expr subclass) required some fiddling in a few places. There are somewhat gross metaprogramming hooks in place to ensure that new statements/expressions continue to implement getSourceRange() and children(). I had to work around a recent clang bug; dgregor actually fixed it already, but I didn't want to introduce a selfhosting dependency on ToT. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125183 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-09static analyzer: Further reduce the analyzer's memory usage when analyzing ↵Ted Kremenek
sqlite3 by 7-10% by recylcing "uninteresting" ExplodedNodes. The optimization involves eagerly pruning ExplodedNodes from the ExplodedGraph that contain practically no difference between the predecessor and successor nodes. For example, if the state is different between a predecessor and a node, the node is left in. Only for the 'environment' component of the state do we not care if the ExplodedNodes are different. This paves the way for future optimizations where we can reclaim the environment objects. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125154 91177308-0d34-0410-b5e6-96231b3b80d8
