Add the IR attribute 'sspstrong'. SSPStrong applies a heuristic to insert stack protectors in these situations: * A Protector is required for functions which contain an array, regardless of type or length. * A Protector is required for functions which contain a structure/union which contains an array, regardless of type or length. Note, there is no limit to the depth of nesting. * A protector is required when the address of a local variable (i.e., stack based variable) is exposed. (E.g., such as through a local whose address is taken as part of the RHS of an assignment or a local whose address is taken as part of a function argument.) This patch implements the SSPString attribute to be equivalent to SSPRequired. This will change in a subsequent patch. llvm-svn: 173230

Add the heuristic to differentiate SSPStrong from SSPRequired. The requirements of the strong heuristic are: * A Protector is required for functions which contain an array, regardless of type or length. * A Protector is required for functions which contain a structure/union which contains an array, regardless of type or length. Note, there is no limit to the depth of nesting. * A protector is required when the address of a local variable (i.e., stack based variable) is exposed. (E.g., such as through a local whose address is taken as part of the RHS of an assignment or a local whose address is taken as part of a function argument.) llvm-svn: 173231

Add the IR attribute 'sspstrong'. SSPStrong applies a heuristic to insert stack protectors in these situations: * A Protector is required for functions which contain an array, regardless of type or length. * A Protector is required for functions which contain a structure/union which contains an array, regardless of type or length. Note, there is no limit to the depth of nesting. * A protector is required when the address of a local variable (i.e., stack based variable) is exposed. (E.g., such as through a local whose address is taken as part of the RHS of an assignment or a local whose address is taken as part of a function argument.) This patch implements the SSPString attribute to be equivalent to SSPRequired. This will change in a subsequent patch. llvm-svn: 173230

Add the IR attribute 'sspstrong'. SSPStrong applies a heuristic to insert stack protectors in these situations: * A Protector is required for functions which contain an array, regardless of type or length. * A Protector is required for functions which contain a structure/union which contains an array, regardless of type or length. Note, there is no limit to the depth of nesting. * A protector is required when the address of a local variable (i.e., stack based variable) is exposed. (E.g., such as through a local whose address is taken as part of the RHS of an assignment or a local whose address is taken as part of a function argument.) This patch implements the SSPString attribute to be equivalent to SSPRequired. This will change in a subsequent patch. llvm-svn: 173230
