This is in gcc.dg/bitint-28.c (FE_INVALID) and gcc.dg/bitint-29.c (FE_INEXACT) for binary and dfp/bitint-8.c new tests. > 2.

This is done in dfp/bitint-7.c test. 2023-09-06 Jakub Jelinek <ja...@redhat.com> PR c/102989 * gcc.dg/torture/bitint-21.c (main): Add tests for -1 for signed only, -1 + epsilon, another (-1, 0) range value and -0. * gcc.dg/torture/bitint-22.c (main): Likewise. * gcc.dg/bitint-28.c: New test. * gcc.dg/bitint-29.c: New test. * gcc.dg/bitint-30.c: New test. * gcc.dg/bitint-31.c: New test. * gcc.dg/dfp/bitint-1.c (main): Add tests for -1 for signed only, -1 + epsilon and -0. * gcc.dg/dfp/bitint-2.c (main): Likewise. * gcc.dg/dfp/bitint-3.c (main): Likewise. * gcc.dg/dfp/bitint-7.c: New test. * gcc.dg/dfp/bitint-8.c: New test.
