[MSVC] Fix for http://llvm.org/PR24132: __declspec(property): double invocations of foo() when compiling foo()->propertyName Removes extra codegen for base expression of MS property call Differential Revision: http://reviews.llvm.org/D13375 llvm-svn: 250265

[MSVC] 'property' with an empty array in array subscript expression. MSVC supports 'property' attribute and allows to apply it to the declaration of an empty array in a class or structure definition. For example: ``` __declspec(property(get=GetX, put=PutX)) int x[]; ``` The above statement indicates that x[] can be used with one or more array indices. In this case, i=p->x[a][b] will be turned into i=p->GetX(a, b), and p->x[a][b] = i will be turned into p->PutX(a, b, i); Differential Revision: http://reviews.llvm.org/D13336 llvm-svn: 254067

[CodeGen] Ignore OpaqueValueExprs that are unique references to their source expressions when iterating over a PseudoObjectExpr's semantic subexpression list. Previously the loop in emitPseudoObjectExpr would emit the IR for each OpaqueValueExpr that was in a PseudoObjectExpr's semantic-form expression list and use the result when the OpaqueValueExpr later appeared in other expressions. This caused an assertion failure when AggExprEmitter tried to copy the result of an OpaqueValueExpr and the copied type didn't have trivial copy/move constructors or assignment operators. This patch adds flag IsUnique to OpaqueValueExpr which indicates it is a unique reference to its source expression (it is not used in multiple places). The loop in emitPseudoObjectExpr ignores OpaqueValueExprs that are unique and CodeGen visitors simply traverse the source expressions of such OpaqueValueExprs. rdar://problem/34363596 Differential Revision: https://reviews.llvm.org/D39562 llvm-svn: 327939

[MSVC] 'property' with an empty array in array subscript expression. MSVC supports 'property' attribute and allows to apply it to the declaration of an empty array in a class or structure definition. For example: ``` __declspec(property(get=GetX, put=PutX)) int x[]; ``` The above statement indicates that x[] can be used with one or more array indices. In this case, i=p->x[a][b] will be turned into i=p->GetX(a, b), and p->x[a][b] = i will be turned into p->PutX(a, b, i); Differential Revision: http://reviews.llvm.org/D13336 llvm-svn: 254067

[MS] Don't escape MS C++ names with \01 It is not needed after LLVM r327734. Now it will be easier to copy-paste IR symbol names from Clang. llvm-svn: 327738
