Can you please provide the testcase? I don't see any attachments. Created attachment 1119657 [details]
Test case
Sorry, not sure what happened there... I'm sure I had attached it...
It was agreed that the testcase is invalidly assuming FP equality which is not guaranteed if excess precision is allowed. That said, with current gcc snapshots it should work as before, but it might change any time in the future. |
