latter is rather a mess to type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169919 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-11Add -fslp-vectorize to enable bb-vectorizeHal Finkel
Add -fslp-vectorize (with -ftree-slp-vectorize as an alias for gcc compatibility) to provide a way to enable the basic-block vectorization pass. This uses the same acronym as gcc, superword-level parallelism (SLP), also common in the literature, to refer to basic-block vectorization. Nadav suggested this as a follow-up to the adding of -fvectorize. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169909 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-11Extend stat query APIs to explicitly specify if the query is forArgyrios Kyrtzidis
a file or directory, allowing just a stat call if a file descriptor is not needed. Doing just 'stat' is faster than 'open/fstat/close'. This has the effect of cutting down system time for validating the input files of a PCH. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169831 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-11PR14558: Compute triviality of special members (etc) at the end of the classRichard Smith
definition, rather than at the end of the definition of the set of nested classes. We still defer checking of the user-specified exception specification to the end of the nesting -- we can't check that until we've parsed the in-class initializers for non-static data members. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169805 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-08Finish implementing 'selected constructor' rules for triviality in C++11. InRichard Smith
the cases where we can't determine whether special members would be trivial while building the class, we eagerly declare those special members. The impact of this is bounded, since it does not trigger implicit declarations of special members in classes which merely *use* those classes. In order to determine whether we need to apply this rule, we also need to eagerly declare move operations and destructors in cases where they might be deleted. If a move operation were supposed to be deleted, it would instead be suppressed, and we could need overload resolution to determine if we fall back to a trivial copy operation. If a destructor were implicitly deleted, it would cause the move constructor of any derived classes to be suppressed. As discussed on cxx-abi-dev, C++11's selected constructor rules are also retroactively applied as a defect resolution in C++03 mode, in order to identify that class B has a non-trivial copy constructor (since it calls A's constructor template, not A's copy constructor): struct A { template<typename T> A(T &); }; struct B { mutable A a; }; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169673 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-08Properly compute triviality for explicitly-defaulted or deleted special members.Richard Smith
Remove pre-standard restriction on explicitly-defaulted copy constructors with 'incorrect' parameter types, and instead just make those special members non-trivial as the standard requires. This required making CXXRecordDecl correctly handle classes which have both a trivial and a non-trivial special member of the same kind. This also fixes PR13217 by reimplementing DiagnoseNontrivial in terms of the new triviality computation technology. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169667 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-08[libclang] Resolve a cursor that points to a macro name inside a #ifdef/#ifndefArgyrios Kyrtzidis

If it causes issues we can revisit and introduce a new kind of cursor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169666 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-08Implement C++03 [dcl.init]p5's checking for value-initialization of referencesRichard Smith

2012-12-07Fix analysis based warnings so that all warnings are emitted when compilingDeLesley Hutchins
with -Werror. Previously, compiling with -Werror would emit only the first warning in a compilation unit, because clang assumes that once an error occurs, further analysis is unlikely to return valid results. However, warnings that have been upgraded to errors should not be treated as "errors" in this sense. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169649 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-07[analyzer] Optimization heuristic: do not reanalyze every ObjC method asAnna Zaks
top level. This heuristic is already turned on for non-ObjC methods (inlining-mode=noredundancy). If a method has been previously analyzed, while being inlined inside of another method, do not reanalyze it as top level. This commit applies it to ObjCMethods as well. The main caveat here is that to catch the retain release errors, we are still going to reanalyze all the ObjC methods but without inlining turned on. Gives 21% performance increase on one heavy ObjC benchmark, which suffered large performance regressions due to ObjC inlining. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169639 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-07[analyzer] Fix r168019 to work with unpruned paths as well.Jordan Rose
This is the case where the analyzer tries to print out source locations for code within a synthesized function body, which of course does not have a valid source location. The previous fix attempted to do this during diagnostic path pruning, but some diagnostics have pruning disabled, and so any diagnostic with a path that goes through a synthesized body will either hit an assertion or emit invalid output. <rdar://problem/12657843> (again) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169631 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-07[analyzer] Remove possible pessimizations from r169563.Jordan Rose
Thanks for reminding me about copy-elision, David. Passing references here doesn't help when we could get move construction in C++11. If we really cared, we'd use std::swap to steal the reference from the temporary arg, but it's probably not /that/ critical outside of Profile anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169570 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-06[analyzer] Avoid ProgramStateRef copy constructors.Jordan Rose
Suggested by David Blaikie. ExplodedNode, CallEvent, and CheckerContext all hang onto their ProgramState, so the accessors can return a reference to the internal state rather than preemptively copying it. This helps avoid temporary ProgramStateRefs, though local variables will still (correctly) do an extra retain and release. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169563 91177308-0d34-0410-b5e6-96231b3b80d8

Passing CXIndexOpt_SkipParsedBodiesInSession as an indexing option will enable the mode where we try to skip bodies that were already parsed in another translation unit.

As the analysis improves, it will continue to add new warnings that are potentially disruptive to existing users. From now on, such warnings will first be introduced under the "beta" flag.
