RE: [plugins] Branch for plugins development created

["Grigori Fursin" <grigori dot fursin at inria dot fr>]

Hi Diego, et al,

As Sebastian mentioned INRIA finally signed copyright transfer form
for FSF last year so our patches can be easily integrated into GCC.

During this week, I will check the current GCC plugins branch and will send you more
info about the current version of Interactive Compilation Interface
to see how we can help with the developments and what we can reuse 
for the GCC plugins (we are naturally interested to test and extend this branch
to simplify further ICI developments). I am working with Zbigniew Chamski and 
Cupertino Miranda to extend ICI so I put them in CC.

The current version of ICI is actually synchronized with the latest GCC trunk,
has a very small code-base and touches minimal parts of the compiler - 
it have been used in various projects
within last 5-6 months to select optimization passes or change their orders
per function to optimize performance/code-size for programs and Linux libraries
at ARC, IBM and STMicro or test the new local releases of a compiler and instrument
program for further analysis. I need to look through all the feedback we got 
from our users to update the Plugins Wiki with the practical 
usage scenarios and different plugins we developed - I will try to 
do it within next few days and will check the proposed GCC plugins API 
to sync with ICI...

Take care and have a good week,
Grigori
