/* PR c/11449. */ /* sign_bit_p() in fold-const.c failed to notice that (int) 0x80000000 was the sign bit of m. As a result, fold_single_bit_test() returned ((unsigned int) m >> 31), and that was eventually passed to invert_truthvalue(), which did not know how to handle RROTATE_EXPR, causing an ICE. */ int foo (int m) { return !(m & ((int) 0x80000000)); }
