* [analyzer] Always include destructors in the analysis CFG.Jordan Rose2012-09-051-1/+0
| | | | | | | | | | | | | | | | | | | | | While destructors will continue to not be inlined (unless the analyzer config option 'c++-inlining' is set to 'destructors'), leaving them out of the CFG is an incomplete model of the behavior of an object, and can cause false positive warnings (like PR13751, now working). Destructors for temporaries are still not on by default, since (a) we haven't actually checked this code to be sure it's fully correct (in particular, we probably need to be very careful with regard to lifetime-extension when a temporary is bound to a reference, C++11 [class.temporary]p5), and (b) ExprEngine doesn't actually do anything when it sees a temporary destructor in the CFG -- not even invalidate the object region. To enable temporary destructors, set the 'cfg-temporary-dtors' analyzer config option to '1'. The old -cfg-add-implicit-dtors cc1 option, which controlled all implicit destructors, has been removed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163264 91177308-0d34-0410-b5e6-96231b3b80d8

* [analyzer] Set the default IPA mode to 'basic-inlining', which excludes C++.Jordan Rose2012-08-211-1/+1
| | | | | | | | | | | | | | | | | | | Under -analyzer-ipa=basic-inlining, only C functions, blocks, and C++ static member functions are inlined -- essentially, the calls that behave like simple C function calls. This is essentially the behavior in Xcode 4.4. C++ support still has some rough edges, and we don't want users to be worried about them if they download and run their own checker. (In particular, the massive number of false positives for analyzing LLVM comes from inlining defensively-written code in contexts where more aggressive assumptions are implicitly made. This problem is not unique to C++, but it is exacerbated by the higher proportion of code that lives in header files in C++.) The eventual goal is to be comfortable enough with C++ support (and simple Objective-C support) to advance to -analyzer-ipa=inlining as the default behavior. See the IPA design notes for more details. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162318 91177308-0d34-0410-b5e6-96231b3b80d8

This uncovered a bug in the handling of -Oz: it would attempt to store the value 2 in the 1-bit bitfield OptimizeSize, leaving a value of 0 and never defining __OPTIMIZE_SIZE__. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161495 91177308-0d34-0410-b5e6-96231b3b80d8

* Add -ffp-contract = { fast | on | off } command line option support.Lang Hames2012-07-061-0/+17
| | | | | | | | | | | | | | | | | | | This flag sets the 'fp-contract' mode, which controls the formation of fused floating point operations. Available modes are: - Fast: Form fused operations anywhere. - On: Form fused operations where allowed by FP_CONTRACT. This is the default mode. - Off: Don't form fused operations (in future this may be relaxed to forming fused operations where it can be proved that the result won't be affected). Currently clang doesn't support the FP_CONTRACT pragma, so the 'On' and 'Off' modes are equivalent. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159794 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | attached to a declaration in the completion string. Since extracting comments isn't free, a new code completion option is introduced. A new code completion option that enables including brief comments into CodeCompletionString should be a, err, code completion option. But because ASTUnit caches global declarations during parsing before even completion consumer is created, the option is duplicated as a translation unit option (in both libclang and ASTUnit, like the option to cache code completion results). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159539 91177308-0d34-0410-b5e6-96231b3b80d8

* Restructure how the driver communicates information about theJohn McCall2012-06-201-15/+9
| | | | | | | | | | | | | | | | | | | | | | | | target Objective-C runtime down to the frontend: break this down into a single target runtime kind and version, and compute all the relevant information from that. This makes it relatively painless to add support for new runtimes to the compiler. Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z, available at the driver level as a better and more general alternative to -fgnu-runtime and -fnext-runtime. This new concept of an Objective-C runtime also encompasses what we were previously separating out as the "Objective-C ABI", so fragile vs. non-fragile runtimes are now really modelled as different kinds of runtime, paving the way for better overall differentiation. As a sort of special case, continue to accept the -cc1 flag -fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak. I won't go so far as to say "no functionality change", even ignoring the new driver flag, but subtle changes in driver semantics are almost certainly not intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158793 91177308-0d34-0410-b5e6-96231b3b80d8
