2012-03-30[analyzer] Do not inline functions which previously reached max blockAnna Zaks
count. This is an optimization for "retry without inlining" option. Here, if we failed to inline a function due to reaching the basic block max count, we are going to store this information and not try to inline it again in the translation unit. This can be viewed as a function summary. On sqlite, with this optimization, we are 30% faster then before and cover 10% more basic blocks (partially because the number of times we reach timeout is decreased by 20%). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153730 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-30When emitting a static local variable in C++, handleJohn McCall
the case that the variable already exists. Partly this is just protection against people making crazy declarations with custom asm labels or extern "C" names that intentionally collide with the manglings of such variables, but the main reason is that we can actually emit a static local variable twice with the requirement that it match up. There may be other cases with (e.g.) the various nested functions, but the main exemplar is with constructor variants, where we can be forced into double-emitting the function body under certain circumstances like (currently) the presence of virtual bases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153723 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-30The UTF16 string referenced by a CFString should go into the __TEXT,__ustringBill Wendling
section. A 'normal' string will go into the __TEXT,__const section, but this isn't good for UTF16 strings. The __ustring section allows for coalescing, among other niceties (such as allowing the linker to easily split up strings). Instead of outputting the UTF16 string as a series of bytes, output it as a series of shorts. The back-end will then nicely place the UTF16 string into the correct section, because it's a mensch. <rdar://problem/10655949> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153710 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-30Add info to ObjCPropertyRefExpr to indicate whether the dot syntax propertyArgyrios Kyrtzidis
reference is going to message the setter, the getter, or both. Having this info on the ObjCPropertyRefExpr node makes it easier for AST clients (like libclang) to reason about the meaning of the property reference. [AST/Sema] -Use 2 bits (with a PointerIntPair) in ObjCPropertyRefExpr to record the above info -Have ObjCPropertyOpBuilder set the info appropriately. [libclang] -When there is an implicit property reference (property syntax using methods) have clang_getCursorReferenced return a cursor for the method. If the property reference is going to result in messaging both the getter and the setter choose to return a cursor for the setter because it is less obvious from source inspection that the setter is getting called. The general idea has the seal of approval by John. rdar://11151621 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153709 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-27Move the emission of strict enum range metadata behind a flag (the sameChandler Carruth
flag as GCC uses: -fstrict-enums). There is a *lot* of code making unwarranted assumptions about the underlying type of enums, and it doesn't seem entirely reasonable to eagerly break all of it. Much more importantly, the current state of affairs is *very* good at optimizing based upon this information, which causes failures that are very distant from the actual enum. Before we push for enabling this by default, I think we need to implement -fcatch-undefined-behavior support for instrumenting and trapping whenever we store or load a value outside of the range. That way we can track down the misbehaving code very quickly. I discussed this with Rafael, and currently the only important cases he is aware of are the bool range-based optimizations which are staying hard enabled. We've not seen any issue with those either, and they are much more important for performance. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153550 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-27[analyzer] Add an option to re-analyze a dead-end path without inlining.Anna Zaks
The analyzer gives up path exploration under certain conditions. For example, when the same basic block has been visited more than 4 times. With inlining turned on, this could lead to decrease in code coverage. Specifically, if we give up inside the inlined function, the rest of parent's basic blocks will not get analyzed. This commit introduces an option to enable re-run along the failed path, in which we do not inline the last inlined call site. This is done by enqueueing the node before the processing of the inlined call site with a special policy encoded in the state. The policy tells us not to inline the call site along the path. This lead to ~10% increase in the number of paths analyzed. Even though we expected a much greater coverage improvement. The option is turned off by default for now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153534 91177308-0d34-0410-b5e6-96231b3b80d8
