--- Comment #5 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:fb1b7e2fec951ba0bf4f68fac6a16929f4f63910 commit r14-8423-gfb1b7e2fec951ba0bf4f68fac6a16929f4f63910 Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Jan 25 13:15:23 2024 +0100 convert: Fix test for out of bounds shift count [PR113574] The following patch is miscompiled, because convert_to_integer_1 for LSHIFT_EXPR tests if the INTEGER_CST shift count is too high, but incorrectly compares it against TYPE_SIZE rather than TYPE_PRECISION. The type in question is unsigned _BitInt(1), which has TYPE_PRECISION 1, TYPE_SIZE 8, and the shift count is 2 in that case. 2024-01-25 Jakub Jelinek <ja...@redhat.com> PR middle-end/113574 * convert.cc (convert_to_integer_1) <case LSHIFT_EXPR>: Compare shift count against TYPE_PRECISION rather than TYPE_SIZE. * gcc.dg/torture/bitint-52.c: New test.
