            Bug ID: 66546
           Summary: No way to disable check for unreachable blocks
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: jit
          Assignee: dmalcolm at gcc dot gnu.org
          Reporter: dmalcolm at gcc dot gnu.org
  Target Milestone: ---

Currently libgccjit always issues a hard error about unconditional blocks.

Some interpreters (e.g. Lua) generate bytecode that may have unreachable
instructions, so it should make it easier for client code if they can have a
way to turn off this check.
