The following binutils patches introduce a new moxie-based target called moxiebox. Moxiebox is a VM developed by the bitcoin community to act as a secure, sandboxed execution environment for bitcoin automation.
See http://github.com/jgarzik/moxiebox for more information. I'm checking these changes in. There's a config.sub change as well that I'll submit through the regular process. Thanks, AG For gcc... 2014-07-27 Anthony Green <gr...@moxielogic.com> * config.gcc: Add moxie-*-moxiebox* configuration. * config/moxie/moxiebox.h: New file. For libgcc... 2014-07-27 Anthony Green <gr...@moxielogic.com> * config.host: Add moxiebox configuration suppport.
