--- Comment #13 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:b960a9c83a93b58a84a7a370002990810675ac5d commit r11-4226-gb960a9c83a93b58a84a7a370002990810675ac5d Author: Richard Biener <rguent...@suse.de> Date: Thu Oct 22 09:29:47 2020 +0200 middle-end/97521 - fix VECTOR_CST expansion This fixes expansion of VECTOR_BOOLEAN_TYPE_P VECTOR_CSTs which when using an integer mode are not always "mask-mode" but may be using an integer mode when there's no supported vector mode. 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 <rguent...@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.
