2009-02-10PTH: Replace ad hoc 'file name' -> 'PTH data' lookup table in the PTH file ↵Ted Kremenek
with an on-disk chained hash table. This data structure is implemented using templates, and will be used to replace similar data structures. This change leads to no visibile performance impact on Cocoa.h, but now we only pay a price for the table on order with the number of files accessed and not the number in the PTH file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64245 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-07Overhaul of Stmt allocation:Ted Kremenek
- Made allocation of Stmt objects using vanilla new/delete a *compiler error* by making this new/delete "protected" within class Stmt. - Now the only way to allocate Stmt objects is by using the new operator that takes ASTContext& as an argument. This ensures that all Stmt nodes are allocated from the same (pool) allocator. - Naturally, these two changes required that *all* creation sites for AST nodes use new (ASTContext&). This is a large patch, but the majority of the changes are just this mechanical adjustment. - The above changes also mean that AST nodes can no longer be deallocated using 'delete'. Instead, one most do StmtObject->Destroy(ASTContext&) or do ASTContextObject.Deallocate(StmtObject) (the latter not running the 'Destroy' method). Along the way I also... - Made CompoundStmt allocate its array of Stmt* using the allocator in ASTContext (previously it used std::vector). There are a whole bunch of other Stmt classes that need to be similarly changed to ensure that all memory allocated for ASTs comes from the allocator in ASTContext. - Added a new smart pointer ExprOwningPtr to Sema.h. This replaces the uses of llvm::OwningPtr within Sema, as llvm::OwningPtr used 'delete' to free memory instead of a Stmt's 'Destroy' method. Big thanks to Doug Gregor for helping with the acrobatics of making 'new/delete' private and the new smart pointer ExprOwningPtr! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63997 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-06Semantic checking for class template declarations andDouglas Gregor
redeclarations. For example, checks that a class template redeclaration has the same template parameters as previous declarations. Detangled class-template checking from ActOnTag, whose logic was getting rather convoluted because it tried to handle C, C++, and C++ template semantics in one shot. Made some inroads toward eliminating extraneous "declaration does not declare anything" errors by adding an "error" type specifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63973 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-06Move StringLiteral to allocate its internal string data using the allocator inTed Kremenek
ASTContext. This required changing all clients to pass in the ASTContext& to the constructor of StringLiteral. I also changed all allocations of StringLiteral to use new(ASTContext&). Along the way, I updated a bunch of new()'s in StmtSerialization.cpp to use the allocator from ASTContext& (not complete). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63958 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-05Put the invalid flag of OwningResult into the Action pointer.Sebastian Redl
This shrinks OwningResult by one pointer. Since it is no longer larger than OwningPtr, merge the two. This leads to simpler client code and speeds up my benchmark by 2.7%. For some reason, this exposes a previously hidden bug, causing a regression in SemaCXX/condition.cpp. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63867 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-04Overhaul BugReporter interface and implementation. The new interface cleans upTed Kremenek
the ownership of BugTypes and BugReports. Now BugReports are owned by BugTypes, and BugTypes are owned by the BugReporter object. The major functionality change in this patch is that reports are not immediately emitted by a call to BugReporter::EmitWarning (now called EmitReport), but instead of queued up in report "equivalence classes". When BugReporter::FlushReports() is called, it emits one diagnostic per report equivalence class. This provides a nice cleanup with the caching of reports as well as enables the BugReporter engine to select the "best" path for reporting a path-sensitive bug based on all the locations in the ExplodedGraph that the same bug could occur. Along with this patch, Leaks are now coalesced into a common equivalence class by their allocation site, and the "summary" diagnostic for leaks now reports the allocation site as the location of the bug (this may later be augmented to also provide an example location where the leak occurs). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63796 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-28Code generation support for C99 designated initializers.Douglas Gregor
The approach I've taken in this patch is relatively straightforward, although the code itself is non-trivial. Essentially, as we process an initializer list we build up a fully-explicit representation of the initializer list, where each of the subobject initializations occurs in order. Designators serve to "fill in" subobject initializations in a non-linear way. The fully-explicit representation makes initializer lists (both with and without designators) easy to grok for codegen and later semantic analyses. We keep the syntactic form of the initializer list linked into the AST for those clients interested in exactly what the user wrote. Known limitations: - Designating a member of a union that isn't the first member may result in bogus initialization (we warn about this) - GNU array-range designators are not supported (we warn about this) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63242 91177308-0d34-0410-b5e6-96231b3b80d8
