gcc front end help

gcc front end help

[HAN,GUOLING]

Hi,
We are going to use gcc as our SystemC synthesizer front end.
It will parse the SystemC (actually a C++) program, construct the
net-list, and build the RTL for each function.
For synthesis purpose, some features in C++ will be interpreted
differently in our system. We don't want the some methods to be
inlined; we don't need the virtual function calls to be expanded into a
series of address calculation.
Could anyone tell me how to forbid function inline in GCC? I tried the
compiler options and changed some code in cp directory. It dose not work.

Could you also help us evaluate the feasibilty of using GCC as our
frontend?

Thanks.

-fno-inline would be the first that comes to mind.

Would be nice if you said what options, and an example of the code.

Sounds interesting.

I suspect this question is best answered in a hardware list, not this 
list.  Also depends upon just what you want gcc to do for you.  The 
more you want it to do (optimizations for example), the less well it 
will do it.  Would be interesting to enhance the edge cases in the 
optimizer and add custom optimization passes to deal well in that 
domain...
