2012-10-10objective-C IRgen: When sending a method to 'super'Fariborz Jahanian
in a category class method, don't read 'isa' pointer. Instead, save the desired OBJC_METACLASS_$_ClassName in __DATA,__objc_superrefs and read that without reading any isa pointers. // rdar://12459358 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165674 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-10Rename ObjCMethodDecl::isSynthesized to isPropertyAccessor.Jordan Rose
This more accurately reflects its use: this flag is set when a method matches the getter or setter name for a property in the same class, and does not actually specify whether or not the definition of the method will be synthesized (either implicitly or explicitly with @synthesize). This renames the setter and backing field as well, and changes the (soon-to-be-obsolete?) XML dump format to use 'property_accessor' instead of 'synthesized'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165626 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-10Apply the same fundamental fix for PR14048 as was applied for PR11905.Chandler Carruth
The issue arises when coercing to/from types of different sizes. We need to be certain that the allocation on either end has sufficient room for the coerced type. When it doesn't, we need to make room, copy across, and then proceed. PR11905 handled the case of storing function arguments back into allocas in the function prolog, this patch handles the case of setting up the function arguments in a call expression. This is actually significantly simpler than the fix for PR11905. It ends up being a trivial change to create a temporary alloca when the source is too small and memcpy across. This should preserve the compile-time fast-isel benefits of doing gep+load sequences and avoiding FCAs. Reviewed by Benjamin and Evgeniy (who fixed PR11905). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165615 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-03This patch enables general varargs support for the 64-bit PPC SVR4 ABI.Bill Schmidt
Most of the pieces for this were already in place, but a proper EmitVAArg is needed for aggregates and complex numbers to be handled. Although the va_list for 64-bit PowerPC SVR4 consists of GPRs 3 through 10 together with the overflow portion of the parameter save area, we can treat va_list as pointing to contiguous memory for all parameters, since the back end forces the parameter GPRs to memory for varargs functions. There is no need at this time to model parameters and return values beyond what the DefaultABIInfo provides. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165143 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-25When performing a ::delete of an object with a virtual destructor,John McCall
be sure to delete the complete object pointer, not the original pointer. This is necessary if the base being deleted is at a non-zero offset in the complete object. This is only required for objects with virtual destructors because deleting an object via a base-class subobject when the base does not have a virtual destructor is undefined behavior. Noticed while reviewing the last four years of cxx-abi-dev activity. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164597 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

2012-09-21ARM: Use a dedicated intrinsic for vector bitwise select.Jim Grosbach
The expression based expansion too often results in IR level optimizations splitting the intermediate values into separate basic blocks, preventing the formation of the VBSL instruction as the code author intended.
