--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Andrew Macleod <amacl...@gcc.gnu.org>: https://gcc.gnu.org/g:efc4255d4393cba3d2232a7152799e1b161c3062 commit r15-802-gefc4255d4393cba3d2232a7152799e1b161c3062 Author: Andrew MacLeod <amacl...@redhat.com> Date: Thu May 2 12:23:18 2024 -0400 Add inferred ranges for range-ops based statements. Gimple_range_fold contains some shorthand fold_range routines for easy user consumption of that range-ops interface, but there is no equivalent routines for op1_range and op2_range. This patch provides basic versions. Any range-op entry which has an op1_range or op2_range implemented can potentially also provide inferred ranges. This is a step towards PR 113879. Default is currently OFF for performance reasons as it dramtically increases the number of inferred ranges. PR tree-optimization/113879 * gimple-range-fold.cc (op1_range): New. (op2_range): New. * gimple-range-fold.h (op1_range): New prototypes. (op2_range): New prototypes. * gimple-range-infer.cc (gimple_infer_range::add_range): Do not add an inferred range if it is VARYING. (gimple_infer_range::gimple_infer_range): Add inferred ranges for any range-op statements if requested. * gimple-range-infer.h (gimple_infer_range): Add parameter.
