Hi, I am new in gcc development and I am focusing on cross-compilers.I have added a few instructions for the target machine in binutils and invoked it using asm() from c program.Now I want to add those instructions to gcc and define that instruction in target.md file.I have a few queries regarding the working of gcc. 1. Do *target.md* files along with* target.cc/.c <http://target.cc/.c> *files help to invoke assembly instructions automatically? 2.What is the input for this ?(.gimple or .cfg files) 3.How does it work internally? 4.I have defined an instruction in target.md alone.But that does not work.How to make it work? 5.What is the use of target.c file and how cost is computed in it? 6.Which file to be examined in rtl-dump of object file for getting the input and output to this stage in gcc?
-- Thanks & Regards Richu Norman
