The patch makes sure to only go the mask-mode expansion if the elements do not line up to cover the full integer mode (when they do and the mode was an actual mask-mode there's no actual difference in both expansions). 2020-10-22 Richard Biener <rguenther@suse.de> PR middle-end/97521 * expr.c (expand_expr_real_1): Be more careful when expanding a VECTOR_BOOLEAN_TYPE_P VECTOR_CSTs. * gcc.target/i386/pr97521.c: New testcase.
