Version and Platform (required):

  • Binary Ninja Version: 4.2.6025-dev Enterprise

Bug Description:
In C-SKY, the fuitos and fuitod instructions treat the integer as signed, rather than unsigned. I couldn't find a way to do this otherwise. But, I'm not sure if this is a limitation of the core, the Rust API, or my brain.
