Hi all, I have just recently had time to checkout and build the GCC plugin branch. I am interested in building a simple plugin to give it a try. After reading through the patches it seems simple enough, I just need to create a shared library that defines the symbols:
pre_translation_unit transform_ctrees transform_gimple transform_cgraph transform_rtl post_translation_unit Does anyone have a template/example autoconf project that is already setup with the needed gcc headers + build infrastructure to create a GCC plugin? Also i noticed that it uses the -export-dynamic flag with libtool which means some platforms like Cygwin are unable to support plugins (Noted in the documentation). Are there any plans for supporting the libtool dlpreopening for plugins so that they can still be used on systems if the plugins are built into GCC? One other thing I noticed is that the configure check for plugin support and inclusion of libltdl is $host based, I.e. pre-defined which hosts support plugins instead of doing a generic check for plugin support. I assume it should be possible to find out from libtool whether shared library support is enabled or not. But then again the $host based check seems to be the way a lot of the other checks in the GCC configure.ac files are done. I mention this because i often use NetBSD which supports shared libraries and is not listed for including libltdl or for enabling plugin support. Otherwise seems like a nice simple implementation. Thanks, Brendon.
