From 626a2c2d4d9d650602c5a618790564977e7f31ef Mon Sep 17 00:00:00 2001 From: LeiWang1999 Date: Tue, 16 Sep 2025 17:48:45 +0800 Subject: [PATCH 1/6] Refactor division simplification in RewriteSimplifier and add corresponding test This commit removes the specific case for rewriting division by a constant float in the RewriteSimplifier. Additionally, a new test is introduced to verify the behavior of float division simplification, ensuring that the division is correctly handled without the previous rewrite logic. --- src/arith/rewrite_simplify.cc | 7 ------- tests/python/arith/test_arith_simplify.py | 12 ++++++++++++ 2 files changed, 12 insertions(+), 7 deletions(-) diff --git a/src/arith/rewrite_simplify.cc b/src/arith/rewrite_simplify.cc index e333f85a3279..65b6e408e2cb 100644 --- a/src/arith/rewrite_simplify.cc +++ b/src/arith/rewrite_simplify.cc @@ -774,13 +774,6 @@ PrimExpr RewriteSimplifier::Impl::VisitExpr_(const DivNode* op) { // Pattern var for lanes in broadcast and ramp PVar lanes; -
