Thank you all of you for your suggestions. Was not mailing for some days because caught up in exams. Interested in this project and working on it.

How to check out our sources using svn and git is described at https://gcc.gnu.org/svn.html and https://gcc.gnu.org/wiki/GitMirror respectively, and 2. perhaps more importantly, how to configure, build and test GCC is described in steps linked from https://gcc.gnu.org/install/ (look for --disable-bootstrap, among other things). If you have any specific question regarding any of these steps, feel free to ask on the mailing list or the IRC. Good luck, Martin

You need to check out the GCC source code from version control and find the files and functions referenced in there (locating pieces of GCC code using find, grep, etc. on the GCC source tree is something you'll need to do a lot), and make sure you can build GCC, run the testsuite, save results from a testsuite run, build and run the testsuite and compare the results of the two runs (this is something that would need doing very many times in the course of any project working on GCC). -- Joseph S.

I've been having interest in this idea I already asked about but forgot to introduce myself. I, Tejas Joshi, studying undergraduate Computer Engineering, Pune University, India. I've worked and still working in interested C,C++ and always had keen interest in Languages and processing. I am a member of team, which has been selected for Smart India hackathon 2018. Working for math.h and complex.h functions is really interesting and want to apply for it. First of all, thanking you Sir Myers for immediate and elaborated response. As far as I think for now, the approach for the problem would be(shortly): 1. There are in-built functions present for ceil / floor / etc. I am suppose to add functions in which existing ones get folded for constant arguments. 2. Expanding them inline for non-constant arguments depending upon target processor and implementing new instruction patterns. Just as Sir said. I have some university level experience of working and programming assembly language under Intel 80386DX architecture. I think it may help for implementing supports for other architectures. Just for start, you mentioned roundeven function as a guide for start. Where can I find these (e.g. real.c) .c files for detailed study of these functions so that I can have broader scenario? I have GCC 7.2.0 installed and could not find it in library nor in libc/. -Tejas Joshi.
