GCC Dump

[Daqing Hou]

Hi, all

We are doing a research project on dumping the tree into an intermediate
format. Ideally, we hope to reuse the options of the front end of gcc.
Previously, the option to switch on the dump function is
``--fdump-translation-unit-the_dump_file_name'' but we found that gcc
3.0.1 has removed this option. Instead, a new option --``dumpbase
<file>'' seemingly works for the purpose, is it? Could you please
explain to us how the options are managed; what is the relation between
gcc.c and toplev.c etc so that we can do the right `surgery'?

Best Regards
