Dear:
I want to get the intermedia represeative of the code of language C
for my later static analysis. I want to build the front and middle end
separately from the whole so that the function is embeded into my
application. I want to retain the structure of passes of GCC(4.3) but
SSA,RTL and related optimization passes. I have read some documents of
Gcc internals but nor understand all. I am novice to programming tools
of GNU. Could you please give me some guidance?
*Maybe there are some flags to set to sovle the problem, but I
simply don't konw, please tell me.
*Maybe I should rewrite the Makefile.in in $(GCCSource)/gcc/, but I
am fuzzy at the detailed files corresponding to the front end and the
specific middle end only including the pass manager but the related
RTL or optimization passes.
There are something obscure to me:
How is the $(GCCSource)/gcc/Makefile.in generated? In my learning,
there should be Makefile.am but none~.
Is there some older version Gcc fittable for my need? I find the
cc1 of Gcc 3.X in Code::Block is just 31K, but the cc1 I build in GCC
4.3 is 21MB. Maybe the update of 3.X to 4.3 is useless to me, Could
please give some hints to me on how to choose a proper version? My
team has write a front end of C compiler but there are too bus to
debug, so I want to make full use of the front end and middle end
represeative of Gcc to substitute our older front end.
Yours sincerely

Thanks a lot for ur help!
