hi, i am using GCC v5.4 on Ubuntu 16.04, x86-64 edition. i run "gcc -dp -dP helloworld.c", and expect to get RTL with assembler output as comment between instructions. to my surprise, there is no new dump file created, even though the program is successfully compiled. my question: why "-dp -dP" does not work? what do i need to do to have them work as expected? thanks.
