            Bug ID: 105
           Summary: sv 0.6 draft support for fail-on-first condition (and
                    trap)
           Product: Libre Shakti M-Class
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: CONFIRMED
          Severity: enhancement
          Priority: ---
         Component: Source Code
          Assignee: lkcl at lkcl.net
          Reporter: lkcl at lkcl.net
                CC: libre-riscv-dev at lists.libre-riscv.org
   NLnet milestone: ---

need fail-on-first support and unit tests for:

* branch (actually, now branch-with-vector-compares)
* standard integer arithmetic (if zero, "fail")
* floating-point arithmetic (if zero or non-zero)
* FP compare (FEQ/FLT etc.) which is a variant of standard int
* LD/ST at end of memory page

good unit test examples: strncpy and strlen
