Andrew and I maintain various GNU toolchain forks that contains a port to the RISC-V architecture <http://riscv.org>. We're finishing up the binutils upstreaming process and would like to submit patches to GCC. When I signed the copyright assignment for binutils I was told that the GCC process was different. GCC's contributing page
https://gcc.gnu.org/contribute.html suggests I send email here to get the GCC copyright assignment forms. Andrew and I would both like to sign the forms for past and future changes, and SiFive (Andrew's employer) will need the employer disclaimer if it's different than the binutils one. Thanks!
