[PATCH v4 6/7] S/390: Use signaling FP comparison instructions

2019-10-01 Thread Ilya Leoshkevich
dg-torture.exp=inf-compare-1.c is failing, because (qNaN > +Inf) comparison is compiled to CDB instruction, which does not signal an invalid operation exception. KDB should have been used instead. This patch introduces a new CCmode and a new pattern in order to generate signaling instructions in t
