Tim Northover	761bcdaf06	ARM: add extra test for addrmode folding. I was worried we might replace a mul with a mul+shift even if there were later uses. Turns out to be unfounded but I'd just as well add an actual test for it. llvm-svn: 302051	2017-05-03 16:54:30 +00:00
Tim Northover	4a01ffbd6a	ARM: avoid handing a deleted node back to TableGen during ISel. When we replaced the multiplicand the destination node might already exist. When that happens the original gets CSEd and deleted. However, it's actually used as the offset so nonsense is produced. Should fix PR32726. llvm-svn: 301983	2017-05-02 22:45:19 +00:00

I was worried we might replace a mul with a mul+shift even if there were later
uses. Turns out to be unfounded but I'd just as well add an actual test for it.
