+       patch #8964: Update tests
+       * tests/simulate/math/isinf-01.c: Update test condition as the expected
+       value of isinf is non-zero in case of argument is infinite.
+       * tests/simulate/math/signbit-01.c: Likewise for signbit function.
+       * tests/simulate/math/modf-np.c: Update test to use avr-libc's modf
+       function.
