Plugin
Hi,
I am working on a static analysis plugin for Mozilla. I noticed the the
C++ frontend has a very convenient pretty-printing API exposed through
(decl|type)_as_string. I use decl_as_string() to get string
representations of types. The scripts are interested in both kinds of
types: the type n
Hey Geoff,
I've learned that you are the author of gengtype/GTY stuff from #gcc.
Would you consider restructuring GTY markers to be more like GCC
attributes? I'm writing code to generate code to convert GCC trees to
JavaScript objects for my GCC plugin. Clearly this is similar to what

Hi Grigori,
I work for Mozilla and recently we developed a few plugins for gcc and
improvised a plugin interface to gcc to support it.
So far we have been utilizing the C++ FE, but now I'm moving into
yanking data out of the middleend. I think we should collaborate on the
plugin interface and c

Hi All,
I was wondering if gcc had a restricted version which would enable me

if you mean you want to prevent certain C features from being used, you
can write a GCC plugin for it. See http://gcc.gnu.org/wiki/GCC_PluginAPI
While developing my plugin I've noticed that many callbacks need to be
guarded with "if (errorcount)" or the plugin will cause a gcc crash due
to receiving less complete data than it expected.
Should the plugin API guard callbacks in invoke_plugin_callbacks() to
avoid 99% of plugins running in

Hi,
I tried to make my plugin compile using only installed headers and
turned out that I needed more gcc headers to be installed.
Unfortunately, I needed C++ headers which currently aren't installed. I

Hi,
Just wanted to give a heads up on what might be the biggest
compiler-upgrade-related performance difference we've seen at Mozilla.
We switched gcc4.3 for gcc4.5 and our automated benchmarking
infrastructure reported 4-19% slowdown on most of our performance
metrics on 32 and 64bit Linux.
