The FuseReductionEpilogue primitive currently supports fusing bias addition epilogues into reduction blocks. This commit extends the primitive to also support ReLU activation functions in epilogue blocks, enabling fusion of patterns like max(temp + bias, 0) into the reduction computation. The implementation adds an EpilogueType enumeration to distinguish between Bias and BiasReLU patterns. The AnalyzeEpiloguePattern method is extended to detect ReLU patterns by checking for MaxNode expressions with zero constants. This commit also adds comprehensive tests in test_tir_schedule_fuse_reduction_epilogue_relu.py, following the same patterns as the existing bias tests. The tests verify structural equality, numerical correctness with per-iteration ReLU semantics, and multiple epilogue block scenarios. All tests pass successfully. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
