Hi all, I am Ajay, a student from India. I'm working on one of my course projects that require me to edit GCC such that it accepts a new pair keywords. The needed functionality for this pair of keyword is similar to that of parenthesis which will allow us to process the block of code enclosed between them. The project requires me to edit gcc to identify this new pair of keywords, then process the block of code enclosed. I am very new to the internals of gcc. I've started studying the GCC internals but getting no clue where to start on my project. Please guide me how to achieve the above functionality. Thanks in advance, Ajay.
