--- Comment #9 from CVS 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:cf2141a0c640fc9b1c497db3f4d5b270f4b8252a commit r13-438-gcf2141a0c640fc9b1c497db3f4d5b270f4b8252a Author: Andrew MacLeod <amacl...@redhat.com> Date: Tue Feb 15 10:17:26 2022 -0500 Add relation between op1 & op2 to lhs_opN_relation API. We use the relation between op1 and op2 to help fold a statement, but it was not provided to the lhs_op1_relation and lhs_op2_relation routines to determine if is also creates a relation between the LHS and either operand. gcc/ PR tree-optimization/104547 * gimple-range-fold.cc (fold_using_range::range_of_range_op): Add the op1/op2 relation to the relation call. * range-op.cc (*::lhs_op1_relation): Add param. (*::lhs_op2_relation): Ditto. (operator_minus::lhs_op1_relation): New. (range_relational_tests): Add relation param. * range-op.h (lhs_op1_relation, lhs_op2_relation): Adjust prototype. gcc/testsuite/ * g++.dg/pr104547.C: New.
