This was motivated by the miscompilation of one of the STAMP applications (Genome), where a stack slot was used as temp storage for a CPU register but not restored when the transaction got aborted and restarted (then, after restart, the program crashed because it used inconsistent data). With the attached patch and in this particular example, the stack slots that are written to in the transaction do not get read during the transaction. (-fno-caller-saves was not a sufficient solution, BTW.)
Are you sure this not due to the missing of tm-logging? We xfail until now for the testsuite but this should be addressed. (Note that I tested genome months ago and it was working correctly.)
By the way, what's the status of this problem of tm-logging? Patrick.
