Re: PING (2 toplevel patches, 2 middle-end)


Is there a known testcase that triggers this
that can be added to the testsuite or is this purely to move this
transformation from fold_rtx_mem?

Every place where this could trigger, is probably caught by fold_rtx_mem first.


Likewise, if your in-progress patch doesn't
work out, you should remember to revert this change, but
I agree that its mostly harmless.


There is already plenty of unused functionality in df.[ch] :-)
