__if_exists __if_not_exists alternative
Hello, Doing meta programming without "__if_exists" is tricky. The result solutions are heavy and take many lines of source code (trait classes). Will gcc include such a feature or alternative in the near future? Also, anyone interested in writing a patch? I can sponsor the result at certain degree with possible cooperation with others, who is interested. Thanks, Dmitry
New GCC ICI (with plug-ins for dynamic pass reordering)
Hello all, In case some of you are interested, we produced a new version of the Interactive Compilation Interface (ICI) for GCC (the tarball for this release can be downloaded here: https://sourceforge.net/project/showfiles.php?group_id=180190&package_id=245842&release_id=539711) To remind, the main aim of the Interactive Compilation Interface (ICI) is to transform GCC into research compiler with minimal changes. In a new version we re-designed the ICI completely based on the valuable feedback from the users after the SMART'07 workshop and GCC HiPEAC'07 tutorial (many thanks to Cupertino Miranda who implemented most of it). The communication with the new ICI is now performed through a dynamically linked GCC plug-in written in C (however any high-level or scripting language can be used with a wrapper). Current implementation includes the ability to reorder or turn specific GCC passes on and off on a function level. We currently work to implement all remaining functions of the specified interface, add passes to extract program features and split analysis and optimization code to enable access to compiler transformations at a fine-grain level. More info is available at the GCC-ICI project website: http://gcc-ici.sourceforge.net I am also finishing/testing a new framework for transparent iterative compilation for GCC (works with compiler flags and pass reordering) which I plan release in about 1.5 months... Yours, Grigori Fursin P.S. I am at the GREPS'07 workshop and PACT'07 conference at the moment so if some of you are there and have questions, I will be happy to have a chat ;) ...

RE: Enabling gcc optimization pass
Hi, Actually, just saw your post, so wanted to say that it is possible with the new GCC-ICI framework. You can find more info here: http://gcc-ici.sourceforge.net There is no checking for pass dependencies and we are working on it now ... Hope it is still of any help ;), Grigori Grigori Fursin, PhD Research Scientist, INRIA Futurs, France http://fursin.net/research -Original Message- From: gcc-owner at gcc dot gnu dot org [mailto:gcc-owner at gcc dot gnu dot org] On Behalf Of Rohit Arul Raj Sent: Thursday, July 26, 2007 10:30 AM To: gcc Subject: Enabling gcc optimization pass Hi all, I have 3 functions- fun1, fun2, fun3 in the same source file and i want to enable one or any of the gcc optimization pass to code in fun2 only, 1. Is it possible to implement this using function attributes or #pragms's? 2. What will be its side-effects? Regards, Rohit
Nvidia PTX backend
I'm thinking about starting a project to add a backend for the Nvidia CUDA PTX instruction set, and eventually a front end that understands the .cu files. Has anybody taken a look at doing this? Just wanted to check to make sure I'm not duplicating work before I begin planning out the changes needed. Also, I expect there will be a lot changes needed to support this, so if anybody else is interested let me know. Justin
