Hi Richu - welcome to GCC development. FWIW I've written a guide for new GCC contributors which you might find helpful: https://gcc-newbies-guide.readthedocs.io/en/latest/index.html Caveat: I'm much more familiar with the frontends/diagnostics, rather than the backends/RTL, so there may be a "frontend" bias in that guide. > 1.How to write comments to rtl or create a custom log file to log > comments > to rtl dump? > 2.How to run testsuite ? > 3.Is there a way to directly run an rtl test case?

Pfa I wrote some notes on dealing with the testsuite, and on running individual cases here: https://gcc-newbies-guide.readthedocs.io/en/latest/working-with-the-testsuite.html Hope this is helpful; good luck Dave
