  "message": "[Metal] Carry export name separately from MSL entry point for name lookup (#24642)\n\nspirv-cross rewrites SPIR-V entry point names to be legal MSL/C\nidentifiers when serializing Metal executables: \u0027.\u0027 characters (codegen\ndispatch names like _dot_general_matmul_i32.i32.i32_...) become \u0027_\u0027, and\nreserved \u0027__\u0027 prefixes (stream builtins like __builtin_splat_i64) are\ndropped. The MetalSPIRV target stored only the rewritten MSL function\nname in PipelineDef.entry_point, and the runtime loaded pipeline-\u003ename\nfrom that same field -- so hal.executable.lookup.function, which\nreferences the original un-rewritten hal.executable.export symbol name,\ncould never match for any export whose name spirv-cross rewrites. This\nbroke every metal-spirv e2e test using such exports\n(dot/dot_general/convolution matmul kernels and\ncompare/dynamic_slice/gather stream builtins).\n\nAdd a dedicated always-present name field to PipelineDef carrying the\ncanonical hal.executable.export symbol name (populated from\nexportOp.getName() in the compiler), appended at the end of the table\nfor backward-compatible vtable layout. The runtime now sources\npipeline-\u003ename (used by lookup_function_by_name) from this field,\nkeeping entry_point as the MTLFunction name for -[MTLLibrary\nnewFunctionWithName:]. The loader falls back to entry_point when name is\nabsent for compatibility.\n\nVerified: dot_general (8/8), compare (15/15), and the full Metal CTS\nsuite\n(command_buffer_tests/queue_tests/dispatch_tests/queue_dispatch_tests,\n4/4) pass.
