--- Comment #32 from GCC 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:6a55e39bdb1fdb570730c08413ebbe744e493411 commit r14-9565-g6a55e39bdb1fdb570730c08413ebbe744e493411 Author: Richard Biener <rguent...@suse.de> Date: Tue Mar 19 15:25:16 2024 +0100 middle-end/113396 - int128 array index and value-ranges The following fixes bogus truncation of a value-range for an int128 array index when computing the maximum extent for a variable array reference. Instead of possibly slowing things down by using widest_int the following makes sure the range bounds fit within the constraints offset_int were designed for. PR middle-end/113396 * tree-dfa.cc (get_ref_base_and_extent): Use index range bounds only if they fit within the address-range constraints of offset_int. * gcc.dg/torture/pr113396.c: New testcase.
