+ <h2>Abstract:</h2>
+ <blockquote>
+ Current transactifying compilers for unmanaged environments (e.g., systems software written 
+ in C/C++) target only word-based software transactional memories (STMs) because the 
+ compiler cannot easily infer whether it is safe to transform a transactional access to a 
+ certain memory location in an object-based way. To use object-based STMs in these 
+ environments, programmers must use explicit calls to the STM or use a restricted language 
+ dialect, both of which are not practical. In this paper, we show how an existing pointer 
+ analysis can be used to let a transactifying compiler for C/C++ use object-based accesses 
+ whenever this is possible and safe, while falling back to word-based accesses otherwise. 
+ Programmers do not need to provide any annotations and do not have to use a restricted 
+ language. Our evaluation also shows that an object-based STM can be significantly faster 
+ than a word-based STM with an otherwise identical design and implementation, even if the 
+ parameters of the latter have been tuned.
