I must have been dreaming the first time I looked at libitm testsuite results on Tru64 UNIX. Of course it cannot work to provide only a single dummy function, but all weak definitions must be backed by dummy definitions on that platform. The following patch does just that, and allows at least some libitm execution tests to pass, despite the lack for named section supported also note in PR other/51174: === libitm tests === Schedule of variations: unix Running target unix Running /vol/gcc/src/hg/trunk/local/libitm/testsuite/libitm.c/c.exp ...
