meson: Introduce target-specific Kconfig Add a target-specific Kconfig. We need the definitions in Kconfig so the minikconf tool can verify they exits. However CONFIG_FOO is only enabled for target foo via the meson.build rules. Two architecture have a particularity, ARM and MIPS. As their translators have been split you can potentially build a plain 32 bit build along with a 64-bit version including the 32-bit subset.

target: Move ArchCPUClass definition to 'cpu.h' The OBJECT_DECLARE_CPU_TYPE() macro forward-declares each ArchCPUClass type. These forward declarations are sufficient for code in hw/ to use the QOM definitions. No need to expose these structure definitions. Keep each local to their target/ by moving them to the corresponding "cpu.h" header.

cpu: Call object_class_dynamic_cast() once in cpu_class_by_name() For all targets, the CPU class returned from CPUClass::class_by_name() and object_class_dynamic_cast(oc, CPU_RESOLVING_TYPE) need to be compatible. Lets apply the check in cpu_class_by_name() for once, instead of having the check in CPUClass::class_by_name() for individual target.

gdbstub: move register helpers into standalone include These inline helpers are all used by target specific code so move them out of the general header so we don't needlessly pollute the rest of the API with target specific stuff. Note we have to include cpu.h in semihosting as it was relying on a side effect before.

hmp: Pass monitor to mon_get_cpu_env() mon_get_cpu_env() is indirectly called monitor_parse_arguments() where the current monitor isn't set yet. Instead of using monitor_cur_env(), explicitly pass the Monitor pointer to the function. Without this fix, an HMP command like "x $pc" crashes like this: #0 0x0000555555caa01f in mon_get_cpu_sync (mon=0x0, synchronize=true) at ../monitor/misc.c:270 #1 0x0000555555caa141 in mon_get_cpu (mon=0x0) at ../monitor/misc.c:294 #2 0x0000555555caa158 in mon_get_cpu_env () at ../monitor/misc.c:299 #3 0x0000555555b19739 in monitor_get_pc (mon=0x555556ad2de0, md=0x5555565d2d40 <monitor_defs+1152>, val=0) at ../target/i386/monitor.c:607 #4 0x0000555555cadbec in get_monitor_def (mon=0x555556ad2de0, pval=0x7fffffffc208, name=0x7fffffffc220 "pc") at ../monitor/misc.c:1681 #5 0x000055555582ec4f in expr_unary (mon=0x555556ad2de0) at ../monitor/hmp.c:387 #6 0x000055555582edbb in expr_prod (mon=0x555556ad2de0) at ../monitor/hmp.c:421 #7 0x000055555582ee79 in expr_logic (mon=0x555556ad2de0) at ../monitor/hmp.c:455 #8 0x000055555582eefe in expr_sum (mon=0x555556ad2de0) at ../monitor/hmp.c:484 #9 0x000055555582efe8 in get_expr (mon=0x555556ad2de0, pval=0x7fffffffc418, pp=0x7fffffffc408) at ../monitor/hmp.c:511 #10 0x000055555582fcd4 in monitor_parse_arguments (mon=0x555556ad2de0, endp=0x7fffffffc890, cmd=0x555556675b50 <hmp_cmds+7920>) at ../monitor/hmp.c:876 #11 0x00005555558306a8 in handle_hmp_command (mon=0x555556ad2de0, cmdline=0x555556ada452 "$pc") at ../monitor/hmp.c:1087 #12 0x000055555582df14 in monitor_command_cb (opaque=0x555556ad2de0, cmdline=0x555556ada450 "x $pc", readline_opaque=0x0) at ../monitor/hmp.c:47 After this fix, nothing is left in monitor_parse_arguments() that can indirectly call monitor_cur(), so the fix is complete.

softfloat: merge floatx80_mod and floatx80_rem The m68k-specific softfloat code includes a function floatx80_mod that is extremely similar to floatx80_rem, but computing the remainder based on truncating the quotient toward zero rather than rounding it to nearest integer. This is also useful for emulating the x87 fprem and fprem1 instructions. Change the floatx80_rem implementation into floatx80_modrem that can perform either operation, with both floatx80_rem and floatx80_mod as thin wrappers available for all targets. There does not appear to be any use for the _mod operation for other floating-point formats in QEMU (the only other architectures using _rem at all are linux-user/arm/nwfpe, for FPA emulation, and openrisc, for instructions that have been removed in the latest version of the architecture), so no change is made to the code for other formats.
