7521d35c06 Silence compiler warnings when compiling with GCC's -Wsign-compare 
When compiling the CPU files with the -Wsign-compare compiler flag, there
are a couple of harmless warnings, e.g.:

cpummu030.c: In function 'm68k_do_rte_mmu030':
cpummu030.c:2745:48: warning: operand of ?: changes signedness from 'int' to 'uae_u32' {aka 'unsigned int'} due to unsignedness of other operand [-Wsign-compare]
  uae_u32 mmu030_opcode_v = (ps & 0x80000000) ? -1 : (oc & 0xffff);
                                                ^~
cpummu030.c:2792:24: warning: comparison of integer expressions of different signedness: 'uae_u32' {aka 'unsigned int'} and 'int' [-Wsign-compare]
    if (mmu030_opcode_v == -1) {
                        ^~
cpummu030.c: In function 'm68k_do_rte_mmu030c':
cpummu030.c:3133:48: warning: operand of ?: changes signedness from 'int' to 'uae_u32' {aka 'unsigned int'} due to unsignedness of other operand [-Wsign-compare]
  uae_u32 mmu030_opcode_v = (ps & 0x80000000) ? -1 : (oc & 0xffff);
                                                ^~
cpummu030.c:3185:50: warning: operand of ?: changes signedness from 'int' to 'uae_u32' {aka 'unsigned int'} due to unsignedness of other operand [-Wsign-compare]
   regs.pipeline_stop = ((ps >> 20) & 15) == 15 ? -1 : (ps >> 20) & 15;
                                                  ^~
fpp.c: In function 'fp_unimp_datatype':
fpp.c:998:54: warning: operand of ?: changes signedness from 'int' to 'uae_u32' {aka 'unsigned int'} due to unsignedness of other operand [-Wsign-compare]
     fsave_data.stag = get_ftag(src, (opclass == 0) ? -1 : size);
                                                      ^~

Let's make sure to use the correct signedness of the target variable to
silence these warnings.

393092b424 68030 MMU update. Unaligned accesses are now new exception handler emulation compatible and retry correctly. Use mmu030_data_buffer_out buffer everywhere instead of special casing MOVEM vs other instructions. 2018-11-23 22:14:39 +02:00

c0efce8232 Another 68030 MMU FPU FSAVE/FRESTORE fix. Use normal state save, 6888x frame (when not including undocumented fields) is small enough to fit in normal state structure. FMOVEM uses different method and should not use x_cp functions. 2018-10-21 21:06:15 +03:00
