2010-06-15Break Frontend's dependency on Rewrite, Checker and CodeGen in shared ↵Daniel Dunbar
library configuration Currently, all AST consumers are located in the Frontend library, meaning that in a shared library configuration, Frontend has a dependency on Rewrite, Checker and CodeGen. This is suboptimal for clients which only wish to make use of the frontend. CodeGen in particular introduces a large number of unwanted dependencies. This patch breaks the dependency by moving all AST consumers with dependencies on Rewrite, Checker and/or CodeGen to their respective libraries. The patch therefore introduces dependencies in the other direction (i.e. from Rewrite, Checker and CodeGen to Frontend). After applying this patch, Clang builds correctly using CMake and shared libraries ("cmake -DBUILD_SHARED_LIBS=ON"). N.B. This patch includes file renames which are indicated in the patch body. Changes in this revision of the patch: - Fixed some copy-paste mistakes in the header files - Modified certain aspects of the coding to comply with the LLVM Coding Standards git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@106010 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-23Improve the AST representation of Objective-C @try/@catch/@finallyDouglas Gregor
statements. Instead of the @try having a single @catch, where all of the @catch's were chained (using an O(n^2) algorithm nonetheless), @try just holds an array of its @catch blocks. The resulting AST is slightly more compact (not important) and better represents the actual language semantics (good). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102221 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-21Overhaul the AST representation of Objective-C message sendDouglas Gregor
expressions, to improve source-location information, clarify the actual receiver of the message, and pave the way for proper C++ support. The ObjCMessageExpr node represents four different kinds of message sends in a single AST node: 1) Send to a object instance described by an expression (e.g., [x method:5]) 2) Send to a class described by the class name (e.g., [NSString method:5]) 3) Send to a superclass class (e.g, [super method:5] in class method) 4) Send to a superclass instance (e.g., [super method:5] in instance method) Previously these four cases where tangled together. Now, they have more distinct representations. Specific changes: 1) Unchanged; the object instance is represented by an Expr*. 2) Previously stored the ObjCInterfaceDecl* referring to the class receiving the message. Now stores a TypeSourceInfo* so that we know how the class was spelled. This both maintains typedef information and opens the door for more complicated C++ types (e.g., dependent types). There was an alternative, unused representation of these sends by naming the class via an IdentifierInfo *. In practice, we either had an ObjCInterfaceDecl *, from which we would get the IdentifierInfo *, or we fell into the case below... 3) Previously represented by a class message whose IdentifierInfo * referred to "super". Sema and CodeGen would use isStr("super") to determine if they had a send to super. Now represented as a "class super" send, where we have both the location of the "super" keyword and the ObjCInterfaceDecl* of the superclass we're targetting (statically). 4) Previously represented by an instance message whose receiver is a an ObjCSuperExpr, which Sema and CodeGen would check for via isa<ObjCSuperExpr>(). Now represented as an "instance super" send, where we have both the location of the "super" keyword and the ObjCInterfaceDecl* of the superclass we're targetting (statically). Note that ObjCSuperExpr only has one remaining use in the AST, which is for "super.prop" references. The new representation of ObjCMessageExpr is 2 pointers smaller than the old one, since it combines more storage. It also eliminates a leak when we loaded message-send expressions from a precompiled header. The representation also feels much cleaner to me; comments welcome! This patch attempts to maintain the same semantics we previously had with Objective-C message sends. In several places, there are massive changes that boil down to simply replacing a nested-if structure such as: if (message has a receiver expression) { // instance message if (isa<ObjCSuperExpr>(...)) { // send to super } else { // send to an object } } else { // class message if (name->isStr("super")) { // class send to super } else { // send to class } } with a switch switch (E->getReceiverKind()) { case ObjCMessageExpr::SuperInstance: ... case ObjCMessageExpr::Instance: ... case ObjCMessageExpr::SuperClass: ... case ObjCMessageExpr::Class:... } There are quite a few places (particularly in the checkers) where send-to-super is effectively ignored. I've placed FIXMEs in most of them, and attempted to address send-to-super in a reasonable way. This could use some review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101972 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19Keep track of the actual storage specifier written on a variable orDouglas Gregor

2010-03-15Introduce a new BufferResult class to act as the return type ofDouglas Gregor
SourceManager's getBuffer() (and similar) operations. This abstract can be used to force callers to cope with errors in getBuffer(), such as missing files and changed files. Fix a bunch of callers to use the new interface. Add some very basic checks for file consistency (file size, modification time) into ContentCache::getBuffer(), although these checks don't help much until we've updated the main callers (e.g., SourceManager::getSpelling()). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98585 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-19Change InitListExpr to allocate the array for holding referencesTed Kremenek
to initializer expressions in an array allocated using ASTContext. This plugs a memory leak when ASTContext uses a BumpPtrAllocator to allocate memory for AST nodes. In my mind this isn't an ideal solution; it would be nice to have a general "vector"-like class that allocates memory using ASTContext, but whose guts could be separated from the methods of InitListExpr itself. I haven't gone and taken this approach yet because it isn't clear yet if we'll eventually want an alternate solution for recylcing memory using by InitListExprs as we are constructing the ASTs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96642 91177308-0d34-0410-b5e6-96231b3b80d8
