What are js instructions and what does javascript(?) have to do with ISA?
- Gaelan 6y agoIIRC, the standard ARM instruction set does include some instructions with "javascript" in the end. I think they're floating point instructions that handle some edge case (NaNs?) in the same way that x86, and therefore the JS spec, do.
