gcc for MRISC32

This is a fork of gcc with support for MRISC32.

Status

The MRISC32 back end for gcc is still in early development. Currently you can only compile very simple C programs (no C++, no libc).

Prerequisites

Ubuntu:

sudo apt install flex bison libbison-dev libgmp-dev libmpfr-dev libmpc-dev

You also have to have an installation of MRISC32 binutils in your PATH.

Building

Build the bootstrap version of GCC

Configure and build:

$ mkdir build
$ cd build
$ ../configure --target=mrisc32-elf --enable-languages=c --without-headers --with-newlib --with-gnu-as --with-gnu-ld
$ make all-gcc

Install:

$ sudo make install-gcc
