--- Comment #1 from Patrick Marlier <patrick.marlier at gmail dot com> 2011-01-27 15:10:18 UTC --- Created attachment 23143 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23143 draft patch This patch makes it work but: (trans-mem.c) examine_call_tm(): I don't know if it is require to test for BUILT_IN_TM_MEMSET because it is never reached. expand_call_tm(): it is required to mark the transaction having transactional stores but should it be also done for MEMCPY/MEMMOVE?
