--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Aldy Hernandez <al...@gcc.gnu.org>: https://gcc.gnu.org/g:2615502971ca11c15f1949c03d93ccfe1ce54f55 commit r13-1840-g2615502971ca11c15f1949c03d93ccfe1ce54f55 Author: Aldy Hernandez <al...@redhat.com> Date: Tue Jul 26 11:03:17 2022 +0200 Handle non constant ranges in irange pretty printer. Technically iranges only exist in constant form, but we allow symbolic ones before arriving in the ranger, so legacy VRP can work. This fixes the ICE when attempting to print symbolic iranges in the pretty printer. For consistency's sake, I have made sure irange::get_nonzero_bits does not similarly ICE on a symbolic range, even though no one should be querying nonzero bits on such a range. This should all melt away when legacy disappears, because all these methods are slated for removal (min, max, kind, symbolic_p, constant_p, etc). Finally, Richi suggested using pp_wide_int in the pretty printer instead of going through trees. I've adapted a test, since dump_generic_node seems to work slightly different. PR tree-optimization/106444 gcc/ChangeLog: * value-range-pretty-print.cc (vrange_printer::visit): Handle legacy ranges. (vrange_printer::print_irange_bound): Work on wide_int's. * value-range-pretty-print.h (print_irange_bound): Same. * value-range.cc (irange::get_nonzero_bits): Handle legacy ranges. gcc/testsuite/ChangeLog: * gcc.dg/tree-ssa/evrp4.c: Adjust.
