re PR tree-optimization/69070 (ICE: tree check: expected real_cst, have ssa_name in gimple_expand_builtin_pow, at tree-ssa-math-opts.c:1541 with -fsignaling-nans and powl())
PR tree-optimization/69070
* tree-ssa-math-opts.c (gimple_expand_builtin_pow): Only test
REAL_VALUE_ISSIGNALING_NAN on arg0 if arg0 is a REAL_CST.
* gcc.dg/pr69070.c: New test.
