Hi all,
I have recently started to study the MIPS architecture. For instance, I wanted to have GCC compile C code into MIPS assembly and run it in SPIM. (I have an Intel machine running Linux).
So I want to try something like this:
gcc -Wall -pedantic -S --march=mips1 test.c
in order to have it generate MIPS assembly.
It does not work. All I get is:
cc1: error: bad value (mips32) for -march= switch cc1: error: bad value (mips32) for -mcpu= switch
Clearly, I need to recompile GCC so it has MIPS in its available architectures. Remark, this is not cross-compiling, because I want GCC to run on an i686 machine, it just generates MIPS code.
Can any one help me do this ?
Thank you Leonel
Cross compiling is the (black) art of building a compiler that runs on Arch X, but generates code for Arch Y. You definitely do not want to replace your system compiler (that is, i686-pc-linux-gnu-gcc) with a mips one, cause then you won't be able to rebuild i686 packages. You want a second compiler to be available capable of handling mips-unknown-linux-gnu.
