Nguyen Anh Quynh cd072b4e20 Merge pull request #22 from JonathonReinhart/supported-arch-api
clean-up uc_support() API
2015-08-24 09:32:22 +08:00
Jonathon Reinhart 11cc9ec9ba clean-up uc_support() API
- rename to more obviously-named uc_arch_supported()
- remove UC_ARCH_ALL and associated test -- There's no point in having this
  API, and it was improperly implemented anyway.
- remove now unneeded archs_enable() and all_arch
- add UNICORN_HAS_PPC test -- This seems to be only partially implemented
