abrown opened PR #1649 from add-shift-i64x2 to master:

This adds a legalization for sshr.i64x2 and fixes some issues I found while doing this. It is based on the changes from #1645 since some of the display changes there made these issues easier to troubleshoot.

I am confused by the use of ishl_64x2 at this point. Shouldn't that be ishr_64x2? The actual results shown are consistent with a signed shift right, not a shift left.

Also I'd be happier if there were a couple more tests here. Could you add a test that 1000-(63)-000 >>signed 63 produces 111-(64)-111 and that 0111-(63)-111 >>signed 63 produces 000-(64)-000 ?

Oh, good catch; yeah, that's likely an oversight from copying other tests. I'll fix these and add the additional tests.
