* target/*/cpu.h: remove softfloat.hAlex Bennée2018-02-215-2/+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.

* m68k: implement movep instructionPavel Dovgalyuk2018-02-143-0/+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.

* accel/tcg: add size paremeter in tlb_fill()Laurent Vivier2018-01-253-6/+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).

* | tcg: Initialize cpu_env genericallyRichard Henderson2017-10-241-5/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | This is identical for each target. So, move the initialization to common code. Move the variable itself out of tcg_ctx and name it cpu_env to minimize changes within targets. This also means we can remove tcg_global_reg_new_{ptr,i32,i64}, since there are no longer global-register temps created by targets. Reviewed-by: Emilio G.

The core of this patch is this change to tcg/tcg.h: > -extern TCGContext tcg_ctx; > +extern TCGContext tcg_init_ctx; > +extern TCGContext *tcg_ctx; Note that for now we set *tcg_ctx to whatever TCGContext is passed to tcg_context_init -- in this case &tcg_init_ctx.

* | tcg: convert tb->cflags reads to tb_cflags(tb)Emilio G. Cota2017-10-241-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
