Hey guys I am reposting this link to GCC-help and GCC to get more feedback on some front-end documentation I added a lot more texinfo mark-up, not quite sure if i can generate a pdf and the .info is quite big to send around. so the link to look at would be: http://code.redbrain.co.uk/cgit.cgi/gcc-dev/tree/gcc/doc/languages.texi?h=documentation There are some texinfo errors I need to correct in the output it compiles fine but the output some of the @file{@var{}} inside verbatim blocks were not liked. I am trying to shape it into a tutorial so I hope that format is ok, but it is less formal that some of the other gcc internals documentation. --Phil
