I see nothing in the GCC 4.5 release notes about plugin support being language specific, and yet if I using the treehydra plugin with Ada (admittedly using a patched GCC 4.3.4 as per the dehydra notes), I get this
gnat1: warning: command line option "-fplugin=/home/linux/gcc-dehydra/dehydra/gcc_treehydra.so" is valid for C/C++ but not for Ada I assume the plan is to have something in the GCC 4 series be agnostic about what front end has generated your GIMPLE. Is this correct? I'd like to be able to analyse GIMPLE structures generated from gnat.
