2017-10-10tcg: remove addr argument from lookup_tb_ptrEmilio G. Cota
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.

2017-09-01hppa: replace cpu_hppa_init() with cpu_generic_init()Igor Mammedov
drop custom cpu_hppa_init() in favor of cpu_generic_init(), to make cpu_generic_init() work all we need is to provide cc->class_by_name callback that would resolve any cpu_model to the sole TYPE_HPPA_CPU to match current behaviour.

2017-01-23target-hppa: Implement linux-user gateway pageRichard Henderson
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 Henderson
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 Henderson
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.
