2012-10-17Set a special flag in class metadata when an Objective-C classJohn McCall
has ivars that require destruction, but none that require anything except zero-initialization. This is common in ARC and (when true throughout a class hierarchy) permits the elimination of an unnecessary message-send during allocation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166088 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-17At -O0, prefer objc_storeStrong with a null new value to theJohn McCall
combination of a load+objc_release; this is generally better for tools that try to track why values are retained and released. Also use objc_storeStrong when copying a block (again, only at -O0), which requires us to do a preliminary store of null in order to compensate for objc_storeStrong's assign semantics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166085 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-25During jump-scope checking, build an ExprWithCleanups immediatelyJohn McCall
into the enclosing scope; this is a more accurate model but is (I believe) unnecessary in my test case due to other flaws. However, one of those flaws is now intentional: blocks which appear in return statements can be trivially observed to not extend in lifetime past the return, and so we can allow a jump past them. Do the necessary magic in IR-generation to make this work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164589 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-20Fix a pair of bugs relating to properties in ARC.John McCall
First, when synthesizing an explicitly strong/retain/copy property of Class type, don't pretend during compatibility checking that the property is actually assign. Instead, resolve incompatibilities by secretly changing the type of *implicitly* __unsafe_unretained Class ivars to be strong. This is moderately evil but better than what we were doing. Second, when synthesizing the setter for a strong property of non-retainable type, be sure to use objc_setProperty. This is possible when the property is decorated with the NSObject attribute. This is an ugly, ugly corner of the language, and we probably ought to deprecate it. The first is rdar://problem/12039404; the second was noticed by inspection while fixing the first. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162244 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-26block literal irgen: several improvements on naming blockFariborz Jahanian
literal helper functions. All helper functions (global and locals) use block_invoke as their prefix. Local literal helper names are prefixed by their enclosing mangled function names. Blocks in non-local initializers (e.g. a global variable or a C++11 field) are prefixed by their mangled variable name. The descriminator number added to end of the name starts off with blank (for first block) and _<N> (for the N+2-th block). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159206 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20Restructure how the driver communicates information about theJohn McCall
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
