rdapp at linux dot ibm.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rdapp at linux dot ibm.com --- Comment #4 from rdapp at linux dot ibm.com --- This also happens on s390x, even with -O0 and no new -march setting. The following line in EtherMac.cc delete outputbuffer.pop() actually emits two calls to cQueue::pop (). On the second call, the queue is empty and the program terminates. Already in the .original pass, a SAVE_EXPR that was there before is not present anymore: if (SAVE_EXPR <cQueue::pop [..] vs. if (cQueue::pop [..] r259771 removes two checks like this: - if (TREE_SIDE_EFFECTS (addr)) - addr = save_expr (addr); Are they really redundant?
