vulkan : added the PAD_REFLECT_1D operation (#26586) vulkan : added PAD_REFLECT_1D operation Implemented the GGML_OP_PAD_REFLECT_1D operation for the Vulkan backend Changes: pad_reflect_1d.comp: implemented the GLSL compute shader with reflection logic vulkan-shaders-gen.cpp: register the shader for SPIR-V compilation ggml-vulkan.cpp: pushed constants struct, pipeline creation, supports_op, dispatch function, compute switch and debug validation Tested the PAD_REFLECT_1D on Intel Iris Xe (Vulkan 1.4, Mesa 25.2.8): Correctness: PAD_REFLECT_1D(type=f32,ne_a=[512,34,2,1],pad_0=10,pad_1=9) = Pass PAD_REFLECT_1D(type=f32,ne_a=[3000,384,4,1],pad_0=10,pad_1=9) = Pass 2/2 tests passed All test are passed Performance: ne_a=[512,34,2,1] -> 5.38 us/run, 24.55 GB/s ne_a=[3000,80,1,1] -> 30.09 us/run, 59.62 GB/s ne_a=[3000,384,4,1] -> 158.31 us/run, 54.39 GB/s Update ggml/src/ggml-vulkan/vulkan-shaders/pad_reflect_1d.comp Co-authored-by: Jeff Bolz --------- Co-authored-by: Jeff Bolz Website: Attestations: macOS/iOS: macOS Apple Silicon (arm64) macOS Apple Silicon (arm64, KleidiAI enabled) DISABLED macOS Intel (x64) iOS XCFramework Linux: Ubuntu x64 (CPU) Ubuntu arm64 (CPU) Ubuntu s390x (CPU)…
