Description Andreas Arnez 2020-03-18 18:41:25 UTC

After fixing problems with the register allocation that affected "grail" on s390x (Bug 417281), "grail" still shows problems on s390x, due to missing support for Iex_ITE expressions for anything else but integer types.  Failures look like this:

ITE(t30,t31,t4)
vex: the `impossible' happened:
   s390_isel_float_expr: cannot reduce tree
