my task is to convert the C-code into VM-Code (VM is a kind of
assembly lang developed by my collegues). for this, i'm taking the GNU
assembly code generated by GCC by compiling with '-S' option.
but the problem is that GCC is generating the GAS code based on the
architecture of the machine it is running on.
is there any way i can set the architecture info to make GCC to
generate the assembly code for a target architecture? ( i.e, running
on SPARC machine can i generate the assembly code for Intel x86 )
thank you in advance.

Sure.
You want to build a cross-compiler, one to run on a sparc, but
produce code for the x86. Look at crosstool
(www.kegel.com/crosstool/) for a great tool to build GNU cross-toolchains,
and also look at the crossgcc mailing list archives
