Hi Where can i see enumeration constant "rtx_names" which is used by macro GET_RTX_NAME to return the name of a RTX when given its code. grep'ed for it in gcc-4.1.1 source but i didnt find exact declaration and definition of above enum constant. Is it automatically generated? Thanks in advance -- Bhaskar, Home: http://www.cse.iitb.ac.in/~bhaskar
