[PATCH RFC 0/3] target/arm: Implement SVE2 fp conversion

Posted by Stephen Long 4 years ago

The only insn left in this category is BFCVTNT. I couldn't find any
helper functions for bfloats so I'm not sure how to approach this insn.

Also, for insn FCVTXNT, I'm not sure if it is ok to set the status rounding
mode to odd like that.
