Enable tracing message flags. These are read from the command-line arguments, which is convenient but may cause problems interacting with the user program, so is not enabled by default. The available options:

• -ddump-cc: print the generated code, kernel table management information, nvcc compiler warnings, and thread & resource statistics

• -ddebug-cc: compile code with debugging symbols, suitable for 'cuda-gdb'

• -ddump-exec: print each kernel name as it is invoked

• -ddump-gc: print memory management information

• -dverbose: other, uncategorised messages

• -fflush-cache: delete the persistent kernel cache
