[11u] RFR: 8247350: [aarch64] assert(false) failed: wrong size of mach node

[Vladimir Kozlov]

Hi Goetz,

11u needs additional fix in macroAssembler_aarch64.cpp:

   void MacroAssembler::stop(const char* msg) {
     address ip = pc();
     pusha();
!   mov(c_rarg0, (address)msg);
!   mov(c_rarg1, (address)ip);
     mov(c_rarg2, sp);
     mov(c_rarg3, CAST_FROM_FN_PTR(address, MacroAssembler::debug64));
     // call(c_rarg3);
     blrt(c_rarg3, 3, 0, 1);
     hlt(0);
--- 2141,2152 ----
   }

   void MacroAssembler::stop(const char* msg) {
     address ip = pc();
     pusha();
!   movptr(c_rarg0, (uintptr_t)(address)msg);
!   movptr(c_rarg1, (uintptr_t)(address)ip);
     mov(c_rarg2, sp);
     mov(c_rarg3, CAST_FROM_FN_PTR(address, MacroAssembler::debug64));
     // call(c_rarg3);
     blrt(c_rarg3, 3, 0, 1);
     hlt(0);

Thanks,
Vladimir
