Fwd: Re: [hatari-devel] 68030 MMU work

[Laurent Sallafranque <laurent.sallafranque@xxxxxxx>]

Hi again,

While reading all the changes (very good work !), I noticed the following (in newcpu.c) :

 		set_x_funcs ();

 		if (mmu_enabled && !currprefs.cachesize) {

 			run_func = m68k_run_mmu;

 		} else {

 			run_func = currprefs.cpu_cycle_exact && currprefs.cpu_model == 68000 ? m68k_run_1_ce :

 				currprefs.cpu_compatible && currprefs.cpu_model == 68000 ? m68k_run_1 :

 #ifdef JIT

 				currprefs.cpu_model >= 68020 && currprefs.cachesize ? m68k_run_jit :

 #endif

 				currprefs.cpu_model >= 68020 && currprefs.mmu_model ? m68k_run_mmu040 :

 				currprefs.cpu_model >= 68020 && currprefs.cpu_cycle_exact ? m68k_run_2ce :

 				currprefs.cpu_compatible ? m68k_run_2p : m68k_run_2;

 		}

 		run_func ();



I thought the 68020 was a 68030 without MMU, was I wrong ? (see line 3666)


Just for info, I've got the following warning :
