In src/hotspot/cpu/aarch64/interp_masm_aarch64.hpp I see this for JDK 11 and below:

class InterpreterMacroAssembler: public MacroAssembler {
 protected:

 protected:
  using MacroAssembler::call_VM_leaf_base;

  // Interpreter specific version of call_VM_base
  using MacroAssembler::call_VM_leaf_base;


This redeclaration of 'using MacroAssembler::call_VM_leaf_base' causes build failures with GCC 10. For example:
