A more complete example of the bug in PR16556 was recently provided, showing that the previous fix was not sufficient. The previous fix is reverted herein. The real problem is that ReplaceNodeResults() uses LowerFP_TO_INT as custom lowering for FP_TO_SINT during type legalization, without checking whether the input type is handled by that routine. LowerFP_TO_INT requires the input to be f32 or f64, so we fail when the input is ppcf128. I'm leaving the test case from the initial fix (r185821) in place, and adding the new test as another crash-only check. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185959 91177308-0d34-0410-b5e6-96231b3b80d8
