Hello,
What about using -x options ?
I red in the GCC 4.4.2 manual that " If you only want some of the stages of compilation, you can use ‘-x’ (or filename suffixes)
to tell gcc where to start, and one of the options ‘-c’, ‘-S’, or ‘-E’ to say where gcc is to stop "
but -x accept only this list of langauge:
Possible values for language
are:
c c-header c-cpp-output
c++ c++-header c++-cpp-output
objective-c objective-c-header objective-c-cpp-output
objective-c++ objective-c++-header objective-c++-cpp-output
assembler assembler-with-cpp
ada
f77 f77-cpp-input f95 f95-cpp-input
java
I guess that if assembler language is one element of the list above, we can tell compiler to start from linking pass: do not run "as" (assembler) nor "cpp" (preprocessor).
So (as an alternative) can we add Gimple to this list of languages and telling compiler to not run cpp (preprocessor) ? Am I right ?
another alternative is to proceed just like we want to add a Gimple GCC front. end. I red that building a GCC front end for any langauge we choose is not a tricky task.
>From your experience handling those forms, can you tell me, are those alternatives feasible or I am trying to invent sth wrong and not interesting at all (cause I think it is a good idea if gcc users can chose the input file they want and tell compiler where to start:. just like -E -s and -c that tell compiler where to stop).
Thank you very much.
Asma.

Ah, no. Nothing of the sort. I've had thought of creating a text
representation for gimple that could be used as input to the compiler,
but so far is just a glimmer of thought, no concrete plans nor time to
implement them.
