2017-10-25disas: Remove unused flags argumentsRichard Henderson1-1/+1
Now that every target is using the disas_set_info hook, the flags argument is unused. Remove it.

2017-10-24tcg: Initialize cpu_env genericallyRichard Henderson1-4/+0
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.

2017-10-24tcg: define tcg_init_ctx and make tcg_ctx a pointerEmilio G. Cota1-1/+1
Groundwork for supporting multiple TCG contexts. 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.

2017-10-24tcg: convert tb->cflags reads to tb_cflags(tb)Emilio G. Cota1-1/+1
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.

2017-10-10tcg: remove addr argument from lookup_tb_ptrEmilio G. Cota1-3/+3
It is unlikely that we will ever want to call this helper passing an argument other than the current PC. So just remove the argument, and use the pc we already get from cpu_get_tb_cpu_state. This change paves the way to having a common "tb_lookup" function. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Emilio G.

2017-01-23target-hppa: Implement linux-user gateway pageRichard Henderson1-4/+81
For linux, page 0 is mapped as an execute-only gateway. A gateway page is a special bit in the page table that allows a B,GATE insn within that page to raise processor permissions. This is how system calls are implemented for HPPA. Rather than actually map anything here, or handle permissions at all, implement the semantics of the actual linux syscall entry points.

2017-01-23target-hppa: Add nullification frameworkRichard Henderson1-4/+224
The HPPA cpu has a unique form of predicated execution in which almost any instruction can set the PSW[N] (or "nullify") bit, which suppresses execution (and even decoding) of the following instruction. Execution of a nullified insn clears the PSW[N] bit. This adds a generic framework for branching over nullified insns, or for sufficiently simple insns, transforming the writeback of the result to a conditional move. In the process, we want to be able to represent PSW[N] as a TCG condition, which implies management of the related tcg temps. Signed-off-by: Richard Henderson <rth@twiddle.net>
2017-01-23target-hppa: Add framework and enable compilationRichard Henderson9-0/+1106
This is just about the minimum required to enable compilation without actually executing any instructions. This contains the HPPACPU structure and the required callbacks, the gdbstub, the basic translation loop, and a translate_one function that always results in an illegal instruction.
