[GSoC2016] Weekly Report of Porting musl to RISC-V Project #1

[Masanori Ogino <masanori.ogino@gmail.com>]

Hello,

The coding period of GSoC 2016 began in Monday. Now it's Friday
midnight (in Japan) so I'd like to report the progress on the project.

I forked lluixhi's RISC-V port of musl [1] as written in my proposal,
and applied some patches to catch up with the bleeding edge of the
library. My WIP branch [2] has no significant differences from the
origin in the arch-dependent part for now.

The riscv-gnu-toolchain has been changed to build musl-based
toolchains. Since the master branch of the toolchain has migrated to
GCC 6.1 containing musl support, the integration is straightforward.
If you want to try it, please execute `make musl` after configuration
with my WIP branch [3].

Now I'm working on building a root filesystem with the musl-based
toolchain to test the port and preparing patches to address some
problems I've found. I hope we will be able to launch a Linux system
based on musl on Spike next week.

Any comments would be appreciated. Please tell me your opinion!

Have a nice weekend!
