* Track whether an AggValueSlot is potentially aliased, and do notJohn McCall2011-08-251-1/+2
| | | | | | | | | | emit call results into potentially aliased slots. This allows us to properly mark indirect return slots as noalias, at the cost of requiring an extra memcpy when assigning an aggregate call result into a l-value. It also brings us into compliance with the x86-64 ABI. llvm-svn: 138599

* Implement function template specialization at class scope extension in ↵Francois Pichet2011-08-141-0/+1
| | | | | | | | | | | | | | | | | Microsoft mode. A new AST node is introduced: ClassScopeFunctionSpecialization. This node holds a FunctionDecl that is not yet specialized; then during the class template instantiation the ClassScopeFunctionSpecialization will spawn the actual function specialization. Example: template <class T> class A { public: template <class U> void f(U p) { } template <> void f(int p) { } // <== class scope specialization }; This extension is necessary to parse MSVC standard C++ headers, MFC and ATL code. BTW, with this feature in, clang can parse (-fsyntax-only) all the MSVC 2010 standard header files without any error. llvm-svn: 137573
* Fix a couple of problems with initialization and assignment toJohn McCall2011-07-281-1/+1
| | | | | | | | | | | __block variables where the act of initialization/assignment itself causes the __block variable to be copied to the heap because the variable is of block type and is being assigned a block literal which captures the variable. rdar://problem/9814099 llvm-svn: 136337

* Switch field destruction over to use the new destroyer-based APIJohn McCall2011-07-121-12/+27
| | | | | | and kill a lot of redundant code. llvm-svn: 134988
* Fix a lot of problems with the partial destruction of arrays:John McCall2011-07-111-67/+168
| | | | | | | | | | | - an off-by-one error in emission of irregular array limits for InitListExprs - use an EH partial-destruction cleanup within the normal array-destruction cleanup - get the branch destinations right for the empty check Also some refactoring which unfortunately obscures these changes. llvm-svn: 134890
* More compiler workarounds. I have to admit that I was notJohn McCall2011-07-091-4/+14
| | | | | | | | expecting so much concentrated oddity on what seemed like a trivial feature. Thanks to François Pichet for doing the MSVC legwork here. llvm-svn: 134813

| | | | llvm-svn: 134785
* A number of array-related IR-gen cleanups.John McCall2011-07-091-56/+214
| | | | | | | | | | | | - Emit default-initialization of arrays that were partially initialized with initializer lists with a loop, rather than emitting the default initializer N times; - support destroying VLAs of non-trivial type, although this is not yet exposed to users; and - support the partial destruction of arrays initialized with initializer lists when an initializer throws an exception. llvm-svn: 134784
* Don't zero-initialize default-initialized local variables that haveDouglas Gregor2011-07-011-1/+18
| | | | | | | | trivial default constructors. This generated-code regression was caused by r131796, which had simplified the handling of default initialization in Sema. Fixes <rdar://problem/9694300>. llvm-svn: 134260

* Honor objc_precise_lifetime in GC mode by feeding the valueJohn McCall2011-06-241-0/+20
| | | | | | | in the variable to an inline asm which gets run when the variable goes out of scope. llvm-svn: 133840
* Change the IR-generation of VLAs so that we capture bounds,John McCall2011-06-241-15/+13
| | | | | | | not sizes; so that we use well-typed allocas; and so that we properly recurse through the full set of variably-modified types. llvm-svn: 133827

* Objective-C fast enumeration loop variables are not retained in ARC, butJohn McCall2011-06-171-4/+38
| | | | | | | | | | | | they should still be officially __strong for the purposes of errors, block capture, etc. Make a new bit on variables, isARCPseudoStrong(), and set this for 'self' and these enumeration-loop variables. Change the code that was looking for the old patterns to look for this bit, and change IR generation to find this bit and treat the resulting variable as __unsafe_unretained for the purposes of init/destroy in the two places it can come up. llvm-svn: 133243

* Automatic Reference Counting.John McCall2011-06-151-16/+240
| | | | | | | | | | Language-design credit goes to a lot of people, but I particularly want to single out Blaine Garst and Patrick Beard for their contributions. Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself, in no particular order. llvm-svn: 133103
* Do not emit stoppoint before emitting debug info for parameters.Devang Patel2011-06-151-3/+1
| | | | | | | - llvm.dbg.declare already receives line number information from ParmDecl - Additional extra stoppoint messes up gdb's understanding of where function body starts. llvm-svn: 133065
* Rework r132576.Devang Patel2011-06-041-2/+0
| | | | | | Emit debug info only if there is an insertion point. The debug info should not force an insertion point. Codegen may later on decide to not emit code for some reason, see extensive comment in CodeGenFunction::EmitStmt(), and debug info should not get in the way. llvm-svn: 132610
