The V8 7.6 update requires the following adjustments to the postmortem debugging metadata constants:

  • v8dbg_class_FixedTypedArrayBase__base_pointer__Object

    • Field moved from FixedTypedArrayBase to JSTypedArray.
    • Postmortem tools should use v8dbg_class_JSTypedArray__base_pointer__Object.
    • Refs: v8/v8@70bd7cf

  • v8dbg_class_FixedTypedArrayBase__external_pointer__uintptr_t

    • Field moved from FixedTypedArrayBase to JSTypedArray.
    • Add new constant: v8dbg_class_JSTypedArray__external_pointer__uintptr_t
    • Refs: v8/v8@70bd7cf

  • v8dbg_class_Map__instance_descriptors_offset

    • Underlying constant was renamed to kInstanceDescriptorsOffset.
    • Postmortem tools should not need to update anything for this constant.
    • Refs: v8/v8@15a7e04

Refs: nodejs/node#28016
