--- Comment #10 from Segher Boessenkool <segher at gcc dot gnu.org> --- Author: segher Date: Fri Apr 19 16:58:01 2019 New Revision: 270460 URL: https://gcc.gnu.org/viewcvs?rev=270460&root=gcc&view=rev Log: tree-call-cdce: If !HONOR_NANS do not make code with NaNs (PR88055) If we don't HONOR_NANS we should not try to use any unordered comparison results. Best case those will just be optimized away; realistically, they ICE. For example, the rs6000 backend has some code that specifically checks we never do this. PR tree-optimization/88055 * tree-call-cdce.c (comparison_code_if_no_nans): New function. (gen_one_condition): Use it if !HONOR_NANS. Modified: trunk/gcc/ChangeLog trunk/gcc/tree-call-cdce.c
