* Definition files can now ascribe indexers to class types. (https://github.com/Roblox/luau/pull/949) * Remove --compile support from the REPL. You can just use luau-compile instead. * When an exception is thrown during parallel typechecking (usually an ICE), we now gracefully stop typechecking and drain active workers before rethrowing the exception. New solver * Include more source location information when we hit an internal compiler error * Improve the logic that simplifies intersections of tables JIT * Save testable type annotations to bytecode * Improve block placement for linearized blocks * Add support for lea reg, [rip+offset] for labels * Unify X64 and A64 codegen for RETURN * Outline interrupt handlers for X64 * Remove global rArgN in favor of build.abi * Change A64 INTERRUPT lowering to match X64 --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>
