2018-02-21target/*/cpu.h: remove softfloat.hAlex Bennée5-2/+5
As cpu.h is another typically widely included file which doesn't need full access to the softfloat API we can remove the includes from here as well. Where they do need types it's typically for float_status and the rounding modes so we move that to softfloat-types.h as well. As a result of not having softfloat in every cpu.h call we now need to add it to various helpers that do need the full softfloat.h definitions.

2018-02-14m68k: implement movep instructionPavel Dovgalyuk3-0/+49
This patch implements movep instruction. It moves data between a data register and alternate bytes within the address space starting at the location specified and incrementing by two. It was designed for the original 68000 and used in firmwares for interfacing the 8-bit peripherals through the 16-bit data bus. Without this patch opcode for this instruction is recognized as some bitop.

2018-01-25accel/tcg: add size paremeter in tlb_fill()Laurent Vivier3-6/+6
The MC68040 MMU provides the size of the access that triggers the page fault. This size is set in the Special Status Word which is written in the stack frame of the access fault exception. So we need the size in m68k_cpu_unassigned_access() and m68k_cpu_handle_mmu_fault(). To be able to do that, this patch modifies the prototype of handle_mmu_fault handler, tlb_fill() and probe_write(). do_unassigned_access() already includes a size parameter. This patch also updates handle_mmu_fault handlers and tlb_fill() of all targets (only parameter, no code change).

Convert all existing readers of tb->cflags to tb_cflags, so that we use atomic_read and therefore avoid undefined behaviour in C11. Note that the remaining setters/getters of the field are protected by tb_lock, and therefore do not need conversion. Luckily all readers access the field via 'tb->cflags' (so no foo.cflags, bar->cflags in the code base), which makes the conversion easily scriptable: FILES=$(git grep 'tb->cflags' target include/exec/gen-icount.h \ accel/tcg/translator.c | cut -f1 -d':' | sort | uniq) perl -pi -e 's/([^.>])tb->cflags/$1tb_cflags(tb)/g' $FILES perl -pi -e 's/([a-z->.]*)(->|\.)tb->cflags/tb_cflags($1$2tb)/g' $FILES Then manually fixed the few errors that checkpatch reported.

2017-09-10target/m68k: Switch fpu_rom from make_floatx80() to make_floatx80_init()Kamil Rytarowski1-22/+22
GCC 4.7.2 on SunOS reports that the values assigned to array members are not real constants: target/m68k/fpu_helper.c:32:5: error: initializer element is not constant target/m68k/fpu_helper.c:32:5: error: (near initialization for 'fpu_rom[0]') rules.mak:66: recipe for target 'target/m68k/fpu_helper.o' failed Convert the array to make_floatx80_init() to fix it. Replace floatx80_pi-like constants with make_floatx80_init() as they are defined as make_floatx80(). This fixes build on SmartOS (Joyent).

call register_m68k_insns() at realize time which makes cpu_m68k_init() typical object creation function. As result we can replace it with cpu_generic_init() which does the same job, reducing code duplication a bit.
