Ramana, Nathan, My opinion was "there is nothing wrong to run application -mno-pic-data-is-text-relative without -msingle-pic-base in a system that offset of data and text it fixed. I am not convenience we should ban it."
However, what Ramana is suggesting is to error out -mno-PDITR with explicit -mno-SPB, which I don't have a strong preference embrace it or not as it will be just a rare and wired command line combination.
