* metal : add top-k MoE fusion Adds a Metal fusion for SOFT_MAX + ARGSORT + GET_ROWS with optional routing-weight normalization and scale, matching the top-k MoE fusion available in the CUDA and Vulkan backends. The fused kernel writes the selected expert ids and routing weights directly, eliding the separate softmax, argsort, get-rows, sum-rows, clamp, div and scale kernels. Assisted-by: pi:llama.cpp/DeepSeek-V4-Flash-Vision-Exp * metal : add MoE weighted reduction fusion Fuses MUL(experts, weights) plus the expert VIEW/ADD chain into one kernel that computes the weighted sum directly. The graph_optimize hook keeps the expert and weight buffers alive until the fused output so the allocator cannot reuse them while the kernel is still reading them. Assisted-by: pi:llama.cpp/DeepSeek-V4-Flash-Vision-Exp * tests : expose MoE weighted reduction in fusion baseline Use 2 experts per token in the generated MoE test models so the Metal MoE weighted reduction fusion (MUL + ADD) is exercised by test-fusion. Assisted-by: pi:llama.cpp/DeepSeek-V4-Flash-Vision-Exp * metal : fuse RMS_NORM + SCALE Adds NORM/RMS_NORM + SCALE fusion to the Metal backend by reusing the norm+mul kernel with a scalar scale flag. Adds test coverage for both NORM+SCALE and RMS_NORM+SCALE and regenerates the fusion baseline. Assisted-by: pi:llama.cpp/DeepSeek-V4-Flash-Vision-Exp * metal : use function constant for RMS_NORM + SCALE Replaces the runtime use_scale karg with a Metal function constant. The norm+mul kernel is compiled with FC_norm_use_scale=false for MUL fusion and FC_norm_use_scale=true for SCALE fusion, so the fused kernel has no runtime branch. Assisted-by: pi:llama.cpp/DeepSeek-V4-Flash-Vision-Exp * metal : use function constant for top-k MoE with_norm Replaces the runtime with_norm karg with a Metal function constant. The top-k MoE kernel is compiled separately for the normalized and non-normalized routing variants, removing the runtime branch. Assisted-by: pi:llama.cpp/DeepSeek-V4-Flash-Vision-Exp * metal : rename moe_weighted_reduction suffix to moe_reduce Shortens the MoE weighted-reduction fusion identifiers, kernel, pipeline, matcher, args struct, and test op name from moe_weighted_reduction to moe_reduce. Assisted-by: pi:llama.cpp/DeepSeek-V4-Flash-Vision-Exp * metal : add MUL_MAT + UNARY and MUL_MAT + ADD + UNARY fusion Adds dense mat-vec activation fusion for sigmoid/silu and bias+softplus. The mat-vec kernels apply the activation/bias epilogue via function constants, avoiding the separate unary/add passes. Assisted-by: pi:llama.cpp/DeepSeek-V4-Flash-Vision-Exp * metal : revert MUL_MAT + UNARY and MUL_MAT + ADD + UNARY fusion The mat-vec activation fusion regressed decode throughput on Qwen3.6-35B-A3B by ~8% (tg32 81.5 vs 88.5 t/s). The regression is caused by loss of concurrency: the standalone unary kernels previously overlapped with other mat-vec work, while fusing the activation into the mat-vec kernel serializes it on the critical path. Assisted-by: pi:llama.cpp/DeepSeek-V4-Flash-Vision-Exp * metal : add SSM_CONV + UNARY (silu) fusion The SSM_CONV kernels apply silu directly via a function constant, eliding the separate unary pass. Regenerates the fusion baseline.
