2012-09-11Revert "[analyzer] Disable STL inlining. Blocked by PR13724."Jordan Rose
While PR13724 is still an issue, it's not actually an issue in the STL. We can keep this option around in case there turn out to be widespread false positives due to poor modeling of the C++ standard library functions, but for now we'd like to get more data. This reverts r163633 / c6baadceec1d5148c20ee6c902a102233c547f62. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163647 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-11Comment parsing: handle non-builtin commands correctly. After semanticDmitri Gribenko
analysis registers a command, it becomes a "known" command for the lexer, since it has an ID. Having this freedom of choice to register a command is a good thing since BriefParser does not need this. But the parser should still invoke the correct semantic analysis method (actOnUnknownCommand) in this case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163646 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-11[analyzer] Use the static type for a virtual call if the dynamic type is worse.Jordan Rose
reinterpret_cast does not provide any of the usual type information that static_cast or dynamic_cast provide -- only the new type. This can get us in a situation where the dynamic type info for an object is actually a superclass of the static type, which does not match what CodeGen does at all. In these cases, just fall back to the static type as the best possible type for devirtualization. Should fix the crashes on our internal buildbot. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163644 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-10Fix PR13784: instantiation of an abstract class in a conditional operator.David Blaikie
A couple of missing "RequireNonAbstractType" calls in conditional operator handling. I looked for opportunities to tie this check in to all relevant callers of PerformCopyInitialization (couldn't be all callers since this is called for base subobject copying too, where it's acceptable to copy abstract types) but the callers varied too much & in many cases had substantial code or conditionals on the RequireNonAbstractType call, the PerformCopyInitialization call, or the code between the two calls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163555 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-10[analyzer] For now, don't inline C++ standard library functions.Jordan Rose
This is a (heavy-handed) solution to PR13724 -- until we know we can do a good job inlining the STL, it's best to be consistent and not generate more false positives than we did before. We can selectively whitelist certain parts of the 'std' namespace that are known to be safe. This is controlled by analyzer config option 'c++-stdlib-inlining', which can be set to "true" or "false". This commit also adds control for whether or not to inline any templated functions (member or non-member), under the config option 'c++-template-inlining'. This option is currently on by default. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163548 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-10Comment AST: TableGen'ize all command lists in CommentCommandTraits.cpp.Dmitri Gribenko
Now we have a list of all commands. This is a good thing in itself, but it also enables us to easily implement typo correction for command names. With this change we have objects that contain information about each command, so it makes sense to resolve command name just once during lexing (currently we store command names as strings and do a linear search every time some property value is needed). Thus comment token and AST nodes were changed to contain a command ID -- index into a tables of builtin and registered commands. Unknown commands are registered during parsing and thus are also uniformly assigned an ID. Using an ID instead of a StringRef is also a nice memory optimization since ID is a small integer that fits into a common bitfield in Comment class. This change implies that to get any information about a command (even a command name) we need a CommandTraits object to resolve the command ID to CommandInfo*. Currently a fresh temporary CommandTraits object is created whenever it is needed since it does not have any state. But with this change it has state -- new commands can be registered, so a CommandTraits object was added to ASTContext. Also, in libclang CXComment has to be expanded to include a CXTranslationUnit so that all functions working on comment AST nodes can get a CommandTraits object. This breaks binary compatibility of CXComment APIs. Now clang_FullComment_getAsXML(CXTranslationUnit TU, CXComment CXC) doesn't need TU parameter anymore, so it was removed. This is a source-incompatible change for this C API. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163540 91177308-0d34-0410-b5e6-96231b3b80d8
