difference between cc and cc1?

[LoTeK]

hi,
I'm reading "computer systems - a programmer's perspective" at the moment and there is an explanation of the "lifetime" of a C-program (hello.c):

hello.c (source) [cpp]--> hello.i (modified source) [cc1]--> hello.s (assembly program) [as]--> hello.o (object code) [ld]--> hello (ex. binary)

so I've done:

Those are internal compiler phases invoked by the userland driver program (gcc, icc, etc) and aren't generally meant for separate use by the programmer.
(And the phases invoked vary from compiler to compiler and depend on which flags are used)

Don't know if it differs when being called as cc, but gcc by default will try to generate object files from its input. You will have to pass extra options to avoid the assembly stage being invoked automatically.
