H A D | test-2248.c | 2911e9b9 Tue Mar 26 21:21:38 GMT 2024 Richard Henderson <richard.henderson@linaro.org> tcg/optimize: Fix sign_mask for logical right-shift
The 'sign' computation is attempting to locate the sign bit that has been repeated, so that we can test if that bit is known zero. That computation can be zero if there are no known sign repetitions.
