Compiling for rx600 with gcc
I have a project that compiles for an RX600 with renasas' gcc compiler (from now on rx-elf-gcc). But I was wondering, shouldn't I be able to compile it with standard gcc? And if, how?
I'm making a docker container for the project, and I would prefere if I did not have to install renesas' compiler, installing it and supplying the activation code, etc.
I have found this piece of documentation, that got me started
https://gcc.gnu.org/onlinedocs/gcc-7.3.0/gcc/RX-Options.html
I then expected to be able to do something like:
$ gcc -mcpu=rx600 -mlittle-endian-data dummy.c
But it gives the error:
gcc: warning: ‘-mcpu=’ is deprecated; use ‘-mtune=’ or ‘-march=’ instead
gcc: error: unrecognized command line option ‘-mlittle-endian-data’
I have tried using -mtune instead, but it seems rx is not a valid option
$ gcc -mtune=rx600 dummy.c
cc1: error: bad value (‘rx600’) for ‘-mtune=’ switch
cc1: note: valid arguments to ‘-mtune=’ switch are: nocona core2 nehalem corei7 westmere sandybridge corei7-avx ivybridge core-avx-i haswell core-avx2 broadwell skylake skylake-avx512 bonnell atom silvermont slm knl intel x86-64 eden-x2 nano nano-1000 nano-2000 nano-3000 nano-x2 eden-x4 nano-x4 k8 k8-sse3 opteron opteron-sse3 athlon64 athlon64-sse3 athlon-fx amdfam10 barcelona bdver1 bdver2 bdver3 bdver4 znver1 btver1 btver2 generic
So, can I add a new hardware model to my installation? Or will these models just simply redirect my to rx-elf-gcc?
As a side note:
$ gcc --version

And the following works:
$ rx-elf-gcc -mcpu=rx600 -mlittle-endian-data -c dummy.c
c gcc cross-compiling

gccis the native compiler frontend program, which targets your local host system. GCC cross-compilers should always be prefixed with target information (like therx-elf-prefix).

You should be able to download the sources, rip out any silly activation stuff from the open source parts (optlib is Renesas' own proprietary stuff), and compile your own GCC for the Renesas RX targets.

Thanks you both for the inputs. My colleague took over the task and compiled the compiler. Nominal Animal, can you post you comment as an answer?
