--- Comment #4 from CVS 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:3f3932a0ec875cb7cca187018f3f8f05f2519d3e commit r10-6602-g3f3932a0ec875cb7cca187018f3f8f05f2519d3e Author: Jakub Jelinek <ja...@redhat.com> Date: Wed Feb 12 22:14:27 2020 +0100 real: Fix roundeven on inf/nan [PR93663] As can be seen in the testcase, roundeven with inf or nan arguments ICE because of those asserts where nothing prevents from is_halfway_below being called with those arguments. The following patch fixes that by just returning false for rvc_inf/rvc_nan like it returns for rvc_zero, so that we handle roundeven with all those values as round. Inf/NaN are not halfway in between two integers... 2020-02-12 Jakub Jelinek <ja...@redhat.com> PR middle-end/93663 * real.c (is_even): Make static. Function comment fix. (is_halfway_below): Make static, don't assert R is not inf/nan, instead return false for those. Small formatting fixes. * gcc.dg/torture/builtin-round-roundeven.c (main): Add tests for DBL_MAX, inf, their negations and nan.
