--- Comment #2 from H.J. Lu <hjl.tools at gmail dot com> --- (In reply to H.J. Lu from comment #1) > It is rotatert vs rotate. How did this happen? There is: /* Convert ROTATERT to ROTATE. */ if (code == ROTATERT) { unsigned int bitsize = GET_MODE_PRECISION (result_mode); code = ROTATE; if (VECTOR_MODE_P (result_mode)) count = bitsize / GET_MODE_NUNITS (result_mode) - count; else count = bitsize - count; } This testcase needs an update.
