--- Comment #10 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:822a0823c012b912f0108a4da257cd97cbcdb7a3 commit r13-4125-g822a0823c012b912f0108a4da257cd97cbcdb7a3 Author: Aldy Hernandez <al...@redhat.com> Date: Sat Nov 12 11:58:07 2022 +0100 [PR68097] Try to avoid recursing for floats in gimple_stmt_nonnegative_warnv_p. It irks me that a PR named "we should track ranges for floating-point hasn't been closed in this release. This is an attempt to do just that. As mentioned in the PR, even though we track ranges for floats, it has been suggested that avoiding recursing through SSA defs in gimple_assign_nonnegative_warnv_p is also a goal. This patch uses a global range query (no on-demand lookups, just global ranges and minimal folding) to determine if the range of a statement is known to be non-negative. PR tree-optimization/68097 gcc/ChangeLog: * gimple-fold.cc (gimple_stmt_nonnegative_warnv_p): Call range_of_stmt for floats.
