i`am using key -da it gives the same result as -all-all or -ce1-all, i`m trying to understand what he is writes to me in dumps, but there is lack of info, except comments in sources, i can`t find any books or electronic resource with infos. Its looks for me as some research in depths of sources of GCC, but i will find the way to emit my instruction no matter what costs!!!!


Sorry for my Engrish
Kind regards Alex Hill.
