Transaction code written by the programmer may be translated, replaced or transformed into a code that is configured to implement transactions according to any of various techniques. A compiler may replace programmer written transaction code into code allowing multiple compatible transaction implementation techniques to be used in the same program, and at the same time. A programmer may write transaction code once using familiar coding styles, but the transaction to be effected according to one of a number of compatible alternative implementation techniques. The compiler may enable the implementation of multiple, alternative transactional memory schemes. The particular technique implemented for each transaction may not be decided until runtime. At runtime, any of the various implemented techniques may be used to effect the transaction and if a first technique fails or is inappropriate for a particular transaction, one or more other techniques may be attempted.
