Hey Asma,
my question is : should I also care about how to translate those tree code al
over the compiler chain: gimple --> ssa --> unssa --> rtl --> ass ...
The idea of GCC's modularization is that a front-end should maximally
care about GIMPLE. All the other transformations are done by the
middle-end.
did you suggest to follow an example of an existing front end that adds some
tree code cause the C++ one seems to be mature and complete.
Yes, the C++ front-end uses quite a lot of own TREE codes, but I would
then start with a very simple one and check how it "translates" the TREE
codes into a GIMPLE sequence, e.g. by looking at the 'gimplify_expr'
language hook which is 'cp_gimplify_expr' for C++.
I hope that helps. If you have any further question about the specific
transformation from TREE codes to GIMPLE, just let us know ...
Andi
