--- Comment #3 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:cb596fd43667f92c4cb037a4ee8b2061c393ba60 commit r12-4788-gcb596fd43667f92c4cb037a4ee8b2061c393ba60 Author: Andrew MacLeod <amacl...@redhat.com> Date: Thu Oct 28 13:31:17 2021 -0400 Perform on-entry propagation after range_of_stmt on a gcond. Propagation is automatically done by the temporal cache when defs are out of date from the names on the RHS, but a gcond has no LHS, and any updates on the RHS are never propagated. Always propagate them. gcc/ PR tree-optimization/102983 * gimple-range-cache.h (propagate_updated_value): Make public. * gimple-range.cc (gimple_ranger::range_of_stmt): Propagate exports when processing gcond stmts. gcc/testsuite/ * gcc.dg/pr102983.c: New.
