- Introduced TestTemplatedConstantMemcpy.hip to reproduce Issue #977. - The test verifies the behavior of hipMemcpyToSymbol with templated constant memory. - Updated CMakeLists.txt to include the new test in the build process.
- SPVRegister: tolerate duplicate variable registration for identical (Ptr, Name) pairs - CHIPBackend: restore invariant in Device::getOrCreateModule, remove early null return - CHIPBindings: remove unreliable runtime fallback with address-range heuristics - HipGlobalVariables: maintain original COMDAT exclusion logic (reverted from initial approach) - TestTemplatedConstantMemcpy: add device-side validation kernel to verify actual data visibility Fixes: #977
