Dear GCC developers,
I tried to use plugin frameworks
svn://gcc.gnu.org/svn/gcc/branches/plugin (old?) and
svn://gcc.gnu.org/svn/gcc/branches/plugins (current).
'plugin' has transform_ctrees() API. - callback on every fndecl
'plugins' has PLUGIN_CXX_CP_PRE_GENERICIZE. - only supported in C++
This patch (for the plugins branch) allows to see AST in C.
Thanks,
Kenji Koyanagi
