--- Comment #14 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:2f0c8f74daef93c0c7b33294213e7db6df58c4d1 commit r11-9259-g2f0c8f74daef93c0c7b33294213e7db6df58c4d1 Author: Richard Biener <rguent...@suse.de> Date: Thu Nov 11 09:40:36 2021 +0100 middle-end/103181 - fix operation_could_trap_p for vector division For integer vector division we only checked for all zero vector constants rather than checking whether any element in the constant vector is zero. It also fixes the adjustment to operation_could_trap_helper_p where I failed to realize that RDIV_EXPR is also used for fixed-point types. It also fixes that handling by properly checking for a fixed_zerop divisor. 2021-11-11 Richard Biener <rguent...@suse.de> PR middle-end/103181 PR middle-end/103248 * tree-eh.c (operation_could_trap_helper_p): Properly check vector constants for a zero element for integer division. Separate floating point and integer division code. Properly handle fixed-point RDIV_EXPR. * gcc.dg/torture/pr103181.c: New testcase. * gcc.dg/pr103248.c: Likewise.
